#25

Firmware 0.5.2-rc.1 Pre-release is out on the Build IDE for Core/Photon/P1/Electron :particle: :particle:

Note: This is a pre-release and is not intended for production yet. We’ve tested this pre-release to the best of our ability and we want to know what you think now! Please understand that some care and attention is necessary when testing this pre-release, and be sure to upgrade to the final release when it’s available. It will not be available by default. To use you must select the version dropdown from the devices drawer. Downgrading back to the current release info is at the bottom of this post.


System Binaries (all devices) & Device Upgrader (Photon & Electron)


v0.5.2-rc.1 Changelog

ENHANCEMENTS

  • [Photon/P1] Restores the default WICED country to Japan #1014

:white_check_mark: Upgrading to this version will now allow you to downgrade remotely OTA to v0.5.0 or earlier without erasing Wi-Fi credentials. There are still some cases where a downgrade will erase credentials, but only if you have explicitly set the country code to something other than the default or JP2. For example, if you set the country code to GB0 or US4, if you downgrade to v0.5.0 your Wi-Fi credentials will be erased. Leaving the country code at default or set to JP2 will not erase credentials when downgrading to v0.5.0. Do not downgrade to v0.5.1 first, and then v0.5.0… this will erase credentials in all cases.

BUGFIXES

  • .syncTime() and .unsubscribe() called on the system thread. Prevents issues when multiple threads try to send messages through the cloud connection or manage the network state shared memory. #1041

Updating System Firmware (and optionally adding Tinker)

To update your device, compile and flash your application in the Build IDE, selecting version 0.5.2-rc.1 (prerelease) in the devices drawer. Update instructions for Core, Photon, P1 and Electron below.

The OTA method using Particle CLI

For devices already online and connected to the cloud, the system firmware can be updated OTA using these commands:

If your device is online, you can attempt to OTA (Over The Air) update these system parts as well with the particle-cli:

Note: You must download system binaries to a local directory on your machine for this to work.

Core:

particle flash YOUR_DEVICE_NAME tinker-0.5.2-rc.1-core.bin

Photon:

particle flash YOUR_DEVICE_NAME system-part1-0.5.2-rc.1-photon.bin
particle flash YOUR_DEVICE_NAME system-part2-0.5.2-rc.1-photon.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

P1:

particle flash YOUR_DEVICE_NAME system-part1-0.5.2-rc.1-p1.bin
particle flash YOUR_DEVICE_NAME system-part2-0.5.2-rc.1-p1.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

Electron:

particle flash YOUR_DEVICE_NAME system-part1-0.5.2-rc.1-electron.bin
particle flash YOUR_DEVICE_NAME system-part2-0.5.2-rc.1-electron.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

The local method over USB using Particle CLI

This requires CLI version 1.12.0 or newer. You can check with particle --version.

If you have the Particle CLI installed already, make sure it is updated with the following command. Make sure the device is in DFU mode and run:
sudo npm update -g particle-cli (note: you can try without sudo first if you wish)

Core:

particle flash --usb tinker-0.5.2-rc.1-core.bin

Photon:

particle flash --usb system-part1-0.5.2-rc.1-photon.bin
particle flash --usb system-part2-0.5.2-rc.1-photon.bin
particle flash --usb tinker (optional)

P1:

particle flash --usb system-part1-0.5.2-rc.1-p1.bin
particle flash --usb system-part2-0.5.2-rc.1-p1.bin
particle flash --usb tinker (optional)

Electron:

particle flash --usb system-part1-0.5.2-rc.1-electron.bin
particle flash --usb system-part2-0.5.2-rc.1-electron.bin
particle flash --usb tinker (optional)

The local DFU-UTIL method

can be applied to offline devices locally over USB using dfu-util

  • Put the device in DFU mode (flashing yellow LED)
  • open a terminal window, change to the directory where you downloaded the files above, and run these commands:

Core:

dfu-util -d 1d50:607f -a 0 -s 0x8005000:leave -D tinker-0.5.2-rc.1-core.bin

Photon:

dfu-util -d 2b04:d006 -a 0 -s 0x8020000 -D system-part1-0.5.2-rc.1-photon.bin
dfu-util -d 2b04:d006 -a 0 -s 0x8060000:leave -D system-part2-0.5.2-rc.1-photon.bin

P1:

dfu-util -d 2b04:d008 -a 0 -s 0x8020000 -D system-part1-0.5.2-rc.1-p1.bin
dfu-util -d 2b04:d008 -a 0 -s 0x8060000:leave -D system-part2-0.5.2-rc.1-p1.bin

Electron:

dfu-util -d 2b04:d00a -a 0 -s 0x8020000 -D system-part1-0.5.2-rc.1-electron.bin
dfu-util -d 2b04:d00a -a 0 -s 0x8040000 -D system-part2-0.5.2-rc.1-electron.bin

Downgrading from 0.5.2-rc.1 to current default firmware

Current defaults

Core: v0.5.1
Photon: v0.5.1
P1: v0.5.1
Electron: v0.5.1

The easiest way to downgrade from a 0.5.2-rc.1 prerelease system firmware, is to use the CLI and run these commands in order. First put the Tinker back on the device, then downgrade the System firmware. This requires CLI version 1.14.2. You can check with particle --version.

If you have the Particle CLI installed already, you can update it with the following combined command. Make sure the device is in DFU mode and run:
sudo npm update -g particle-cli (note: you can try without sudo first if you wish)

  1. Make sure Tinker is installed, instead of a 0.5.2-rc.1 app that you may currently have running on your device. Have the device in DFU mode and run:
particle flash --usb tinker
  1. Make sure the device is in DFU mode and run:
particle update

This works for downgrading without specifying --target X.Y.Z because the 0.5.2-rc.1 pre-release firmware is not the default, and therefor particle update effectively downgrades your firmware.

#26

Note: This is a Release and may be used for production. Any known issues are likely slated for 0.5.3-rc.1 and 0.6.0-rc.1 releases (check Github issues). It is available by default for all devices. To use, select the 0.5.2 version dropdown from the devices drawer. Please read the note below about downgrading.

Note: Some users previously had last used 0.5.2-rc.1 on Core/Photon/P1 devices. Since this target is no longer available for those devices, please re-flash them with 0.5.2. Pre-release 0.5.2-rc.1 is still available for the Electron since it may be more difficult or costly to upgrade these remote devices. Please do upgrade when you can to 0.5.2, however this is technically the same firmware as 0.5.2-rc.1. As usual, you will have to locally upgrade the Electron system firmware to 0.5.2 first. Electron system version identification has been improved. You should only need to refresh/reload the Build IDE to see the new version.

#29

More info on the digitalRead() interfering with analogRead() fix from changelog:

Updated notes in analogRead(), will be live in docs shortly.
https://docs.particle.io/reference/firmware/photon/#analogread-adc-

Before 0.5.3 Note: do not set the pinMode() with analogRead(). The pinMode() is automatically set to AN_INPUT the first time analogRead() is called for a particular analog pin. If you explicitly set a pin to INPUT or OUTPUT after that first use of analogRead(), it will not attempt to switch it back to AN_INPUT the next time you call analogRead() for the same analog pin. This will create incorrect analog readings.


Since 0.5.3 Note: you do not need to set the pinMode() with analogRead(). The pinMode() is automatically set to AN_INPUT any time analogRead() is called for a particular analog pin, if that pin is set to a pinMode other than AN_INPUT. If you explicitly set a pin to INPUT, INPUT_PULLUP, INPUT_PULLDOWN or OUTPUT before using analogRead(), it will switch it back to AN_INPUT before taking the reading. If you use digitalRead() afterwards, it will automatically switch the pinMode back to whatever you originally explicitly set it to.

Firmware 0.6.0-rc.1 Pre-release is out on the Build IDE for Core/Photon/P1/Electron

This is a big one!

  • The majority of Docs updates for 0.6.0 are going to roll out and be live between now and tomorrow sometime.
  • Please make sure to update your CLI to v1.16.0 for proper handling of 3 system parts for Electron.
  • You must update your Electron to v0.5.3-rc.2 first before attempting to use OTA or YModem transfer to update to v0.6.0-rc.1. If you use DFU over USB, you can update to v0.6.0-rc.1 directly, but make sure you have installed v1.16.0 of the CLI first.

Note: This is a pre-release and is not intended for production yet. We’ve tested this pre-release to the best of our ability and we want to know what you think now! Please understand that some care and attention is necessary when testing this pre-release, and be sure to upgrade to the final release when it’s available. It will not be available by default. To use you must select the version dropdown from the devices drawer. Downgrading back to the current release info is at the bottom of this post.

System Binaries (all devices) & Device Upgrader (Photon & Electron)


Updating System Firmware (and optionally adding Tinker)

To update your device, compile and flash your application in the Build IDE, selecting version 0.6.0-rc.1 (prerelease) in the devices drawer. Update instructions for Core, Photon, P1 and Electron below.

The OTA method using Particle CLI

For devices already online and connected to the cloud, the system firmware can be updated OTA using these commands:

If your device is online, you can attempt to OTA (Over The Air) update these system parts as well with the particle-cli:

Note: You must download system binaries to a local directory on your machine for this to work.

Core:

particle flash YOUR_DEVICE_NAME tinker-0.6.0-rc.1-core.bin

Photon:

particle flash YOUR_DEVICE_NAME system-part1-0.6.0-rc.1-photon.bin
particle flash YOUR_DEVICE_NAME system-part2-0.6.0-rc.1-photon.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

P1:

particle flash YOUR_DEVICE_NAME system-part1-0.6.0-rc.1-p1.bin
particle flash YOUR_DEVICE_NAME system-part2-0.6.0-rc.1-p1.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

Electron:

particle flash YOUR_DEVICE_NAME system-part1-0.6.0-rc.1-electron.bin
particle flash YOUR_DEVICE_NAME system-part2-0.6.0-rc.1-electron.bin
particle flash YOUR_DEVICE_NAME system-part3-0.6.0-rc.1-electron.bin
particle flash YOUR_DEVICE_NAME tinker (optional)

The local method over USB using Particle CLI

This requires CLI version 1.16.0 or newer. You can check with particle --version.

If you have the Particle CLI installed already, make sure it is updated with the following command. Make sure the device is in DFU mode and run:
sudo npm update -g particle-cli (note: you can try without sudo first if you wish)

Core:

particle flash --usb tinker-0.6.0-rc.1-core.bin

Photon:

particle flash --usb system-part1-0.6.0-rc.1-photon.bin
particle flash --usb system-part2-0.6.0-rc.1-photon.bin
particle flash --usb tinker (optional)

P1:

particle flash --usb system-part1-0.6.0-rc.1-p1.bin
particle flash --usb system-part2-0.6.0-rc.1-p1.bin
particle flash --usb tinker (optional)

Electron:

particle flash --usb system-part1-0.6.0-rc.1-electron.bin
particle flash --usb system-part2-0.6.0-rc.1-electron.bin
particle flash --usb system-part3-0.6.0-rc.1-electron.bin
particle flash --usb tinker (optional)

The local DFU-UTIL method

can be applied to offline devices locally over USB using dfu-util

  • Put the device in DFU mode (flashing yellow LED)
  • open a terminal window, change to the directory where you downloaded the files above, and run these commands:

Core:

dfu-util -d 1d50:607f -a 0 -s 0x8005000:leave -D tinker-0.6.0-rc.1-core.bin

Photon:

dfu-util -d 2b04:d006 -a 0 -s 0x8020000 -D system-part1-0.6.0-rc.1-photon.bin
dfu-util -d 2b04:d006 -a 0 -s 0x8060000:leave -D system-part2-0.6.0-rc.1-photon.bin

P1:

dfu-util -d 2b04:d008 -a 0 -s 0x8020000 -D system-part1-0.6.0-rc.1-p1.bin
dfu-util -d 2b04:d008 -a 0 -s 0x8060000:leave -D system-part2-0.6.0-rc.1-p1.bin

Electron:

dfu-util -d 2b04:d00a -a 0 -s 0x8060000 -D system-part1-0.6.0-rc.1-electron.bin
dfu-util -d 2b04:d00a -a 0 -s 0x8020000 -D system-part2-0.6.0-rc.1-electron.bin
dfu-util -d 2b04:d00a -a 0 -s 0x8040000 -D system-part3-0.6.0-rc.1-electron.bin

Downgrading from 0.6.0-rc.1 to current default firmware

Current defaults

Core: v0.5.2
Photon: v0.5.2
P1: v0.5.2
Electron: v0.5.2

The easiest way to downgrade from a 0.6.0-rc.1 prerelease system firmware, is to use the CLI and run these commands in order. First put the Tinker back on the device, then downgrade the System firmware. This requires CLI version 1.15.0. You can check with particle --version.

If you have the Particle CLI installed already, you can update it with the following combined command. Make sure the device is in DFU mode and run:
sudo npm update -g particle-cli (note: you can try without sudo first if you wish)

  1. Make sure Tinker is installed, instead of a 0.6.0-rc.1 app that you may currently have running on your device. Have the device in DFU mode and run:
particle flash --usb tinker
  1. Make sure the device is in DFU mode and run:
particle update

This works for downgrading without specifying --target X.Y.Z because the 0.6.0-rc.1 pre-release firmware is not the default, and therefor particle update effectively downgrades your firmware.

Electron Firmware and Dev
PHOTON HARD FAULT - not recover
Particle update command
#35

Hey all!

We just updated latest and master branches of the firmware repo to be current with release/v0.5.3.

Because we had to force push these changes, you’ll likely have merge conflicts if you git pull the latest changes for those branches. Because of this you will need to hard reset your local copy of each branch to match the remote.

:warning: Before doing this, make sure you save any changes you have been making in your local copy of latest or master (hopefully you are not doing that though and using a feature/branch based on these ;-))

Hard Reset Lastest

git checkout latest && git fetch origin && git reset --hard origin/latest

Hard Reset Master

git checkout master && git fetch origin && git reset --hard origin/master

You should now be sync’d up again with the most recent latest and master


Also, some changes to note:

The latest branch is being depreciated, and release/stable is taking it’s place. We will reiterate this during the 0.6.0 release which is coming.

We also have release/stable-0.5.x which is the latest 0.5.x default release (as of this post it’s 0.5.3)

Firmware 0.6.0 is out on the Web IDE for Core/Photon/P1/Electron - and the Particle CLI has been updated to 1.18.0

Note: This is a Release and may be used for production. Any known issues are likely slated for 0.7.0-rc.1 (check Github issues). It is available by default for all devices. To use, select the 0.6.0 version dropdown from the devices drawer.

Note: If you have previously last used one of the prerelease versions of 0.6.0 on a Core/Photon/P1 device, please re-flash it with 0.6.0. You must upgrade (locally preferred) the Electron system firmware to 0.6.0 first before you can OTA new user apps.

Note: You must update your Electron to (v0.5.3, v0.5.3-rc.2, or v0.5.3-rc.3) first before attempting to use OTA or YModem transfer to update to v0.6.0. If you use DFU over USB, you can update to v0.6.0 directly, but make sure you have installed v1.18.0 of the CLI first.

Hey all!

We updated release/stable and master branches of the firmware repo to be current with release/v0.6.0.

:exclamation: release/stable is taking the place of latest which will be deleted :no_entry_sign:

Because we had to force push these changes, you’ll likely have merge conflicts if you git pull the latest changes for those branches. Because of this you will need to hard reset your local copy of each branch to match the remote.

:warning: Before doing this, make sure you save any changes you have been making in your local copy of release/stable or master (hopefully you are not doing that though and using a feature/branch based on these ;-))

Hard Reset release/stable

git checkout release/stable && git fetch origin && git reset --hard origin/release/stable

Hard Reset master

git checkout master && git fetch origin && git reset --hard origin/master

You should now be sync’d up again with the most recent release/stable and master, you will see:

HEAD is now at d17554a automate the Core build and binary collection

Just to reiterate from last time:

We also have release/stable-0.5.x which is the latest 0.5.x default release (as of this post it’s 0.5.3)

Firmware 0.6.1-rc.1 Pre-release is out on the Web IDE for Core/Photon/P1/Electron

Note: This is a pre-release and is not intended for production yet. We’ve tested this pre-release to the best of our ability and we want to know what you think now! Please understand that some care and attention is necessary when testing this pre-release, and be sure to upgrade to the final release when it’s available. It will not be available by default. To use you must select the version dropdown from the devices drawer. Downgrading back to the current release info is at the bottom of this post.

0.6.1-rc.1 Changelog

FEATURES

  • [PR #1190] [Implements #1114] Added ability to mirror MODE/SETUP button to any GPIO, available from time of boot, active high or low.
  • [PR #1182] [Fixes #687] [Docs] Added WiFi.set|getListenTimeout() | Cellular.set|getListenTimeout() to override the automatic new Listening Mode timeout (Wi-Fi = no timeout by default, Cellular = 5 minute timeout by default).
  • [PR #1154] Added low_battery system event, which is generated when low battery condition is detected. This is when the battery falls below the SoC threshold (default 10%, max settable 32%). The event can only be generated again if the system goes from a non-charging to charing state after the event is generated. The event doesn’t carry any data.
  • [PR #1144] Added tracking of ACKs for published events (see WITH_ACK flag for Particle.publish())
  • [PR #1135] [Fixes #1116] [Fixes #965] New Time API’s! Time.isValid() | Particle.syncTimePending() | Particle.syncTimeDone() | Particle.timeSyncedLast()
  • [PR #1127] [PR #1213] Added support for runtime logging configuration, which allows to enable logging on already running system via USB control requests. Disabled by default to save flash memory space. (note: this feature is not fully baked with tool support)
  • [PR #1120] [Implements #1059] [P1] Added extra spare pin to P1 (P1S6) with GPIO and PWM support.
  • [PR #1204] [Implements #1113] RGB LED pins can be mirrored to other PWM capable pins via RGB.mirrorTo(). Common Anode/Cathode LED and Bootloader compatible. See PR for usage.
  • [PR #1205] [Closes #569] [Closes #976] [Closes #1111] By implementing a centralized LED service and theme “engine” for system LED signaling, giving users the ability to apply custom LED colors and patterns for system events.

ENHANCEMENTS

  • [PR #1191] Added more Arduino Library compatibility
  • [PR #1188] [Implements #1152] Added SPI API’s: SPISettings | SPI.beginTransaction() | SPI.endTransaction()
  • [PR #1169] Updated system communication logging with new logging API
  • [PR #1160] [Electron] Modem USART paused via HW_FLOW_CONTROL (RTS) before going into sleep with SLEEP_NETWORK_STANDBY. Receives and buffers small messages while system sleeping.
  • [PR #1159] [Closes #1085] [Closes #1054] Added support for GCC 5.4.x
  • [PR #1151] [Closes #977] Added System events for cloud/network connection state changes
  • [PR #1122] Attach to host even if Serial, USBSerial1 and Keyboard/Mouse are disabled, so that “Control Interface” that receives vendor requests is still accessible.
  • [PR #1097] [Implements #1032] When flashing (OTA/YModem) an invalid firmware binary (that the device ignores) it will post an event describing why the binary was not applied.
  • [PR #1203] [PR #1212] Automatic bootloader updates have returned to the Electron. v9 bootloader has been added to firmware release >=0.6.1-rc.1 for Photon/P1/Electron. After updating your system firmware, a new v9 bootloader will be applied to your device if required. v9 includes support for SETUP/MODE button and RGB LED mirroring at the bootloader level of operation. Also included are updates to USB DFU mode so that Windows users do not need to install separate drivers via Zadig. Bootloader GREEN and WHITE LED flashing speeds (Firmware Reset modes) are faster now as well (you won’t see these unless you have loaded user firmware to the Backup location).
  • [PR #1125] Breaks on-going network connection when Sleep stop mode is called, thereby speeding up the time to entering sleep when using SYSTEM_THREAD(ENABLED).

BUGFIX

  • [PR #1186] Fixed issue where USB Serial might deadlock when interrupts are disabled while using DEBUG_BUILD=y
  • [PR #1179] [Fixes #1178] [Fixes #1060] [Electron] Bootloader build was failing, fixed and added to CI.
  • [PR #1158] [Fixes #1133] [Electron] Before sleeping, now waits for server sent confirmable messages to be acknowledged, in addition to previous behavior of device generated confirmable messages being acknowledged. Reduces data usage.
  • [PR #1156] [Fixes #1155] System.sleep(30) wasn’t reapplying power to the network device after set time.
  • [PR #1147] [Electron] Fixed approx. -0.1V offset on FuelGauge().getVCell() readings
  • [PR #1145] [Fixes #973] Particle.connect() now blocks loop() from running until Particle.connected() is true in single threaded SEMI_AUTOMATIC mode.
  • [PR #1140] [Fixes #1138] [Fixes #1104] [Electron] Fixed modem USART and buffer handling
  • [PR #1130] Particle.subscribe() used with same events but changing scope between PUBLIC and PRIVATE or vice versa would potentially result in non-registered subscriptions. This was also crashing the GCC virtual device with a segfault when subscription checksums were calculated.

INTERNAL

  • [PR #1196] Re-enable GNU extensions for libc globally. Fixes build with ARM GCC 4.9.3 Q1.
  • [PR #1189] Typo caused a warning during compilation in wiring/no_fixture Cellular tests.
  • [PR #1184] [Electron] moved cellular HAL and its direct dependencies from module 2 to module 3 to free up space (this is system-part3 was reduced in size, while system-part1 was increased)
  • [PR #1167] [Fixes #1036] [GCC Virtual Device] workaround for 100% CPU usage problem.
  • [PR #1146] [Closes #1040] Added asserts for checking that network calls are run on system thread.
  • [PR #1134] [GCC Virtual Device] Error in socket_hal’s socket_receive() logic caused random cloud connection errors.

Hey all!

I’m working on releasing 0.6.1-rc.1 firmware docs to the prerelease-docs site, and I had some troubles with git subtrees. Maybe some of you feel my pain if you’ve used subtrees :smile:

If you use the develop branch of the firmware repo, read on… otherwise please disregard below the fold.


I just had to force push develop back to the way it was earlier today. Because of this you’ll likely have merge conflicts if you git pull the latest changes from develop. You will need to hard reset your local copy of develop to match the remote.

:warning: Before doing this, make sure you save any changes you have been making in your local copy of develop (hopefully you are not doing that though and using a feature/branch based on these ;-))

Hard Reset develop

git checkout develop && git fetch origin && git reset --hard origin/develop

You should now be sync’d up again with the most recent develop, you will see:

HEAD is now at b82c352 added LED Themes to 0.6.1-rc.1 Changelog [ci skip]

Firmware 0.6.1-rc.2 Pre-release is out on the Web IDE for Core/Photon/P1/Electron

released on production servers January 23, 2017

:warning: Please Note: The bootloader on Electron/Photon/P1 will update to v11 automatically with this update. Make sure your device is connected to a stable power source and do not remove power until after the device reboots and is running. It happens so quickly right after the device resets and boots that you won’t notice any special RGB LED signaling for this.


Note: This is a pre-release and is not intended for production yet. We’ve tested this pre-release to the best of our ability and we want to know what you think now! Please understand that some care and attention is necessary when testing this pre-release, and be sure to upgrade to the final release when it’s available. It will not be available by default. To use you must select the version dropdown from the devices drawer. Downgrading back to the current release info is at the bottom of this post.

Note: You must update your Electron to v0.5.3 first before attempting to use OTA or YModem transfer to update to >= v0.6.0. If you use DFU over USB, you can update to >= v0.6.0 directly, but make sure you have installed v1.18.0 of the CLI first.

ENHANCEMENTS

  • [PR #1216] Improved Arduino Compatibility (now supported by default, added PARTICLE_NO_ARDUINO_COMPATIBILITY=y command line option for disabling)
  • [PR #1217] Added Windows, Mac command, & Unix/Linux meta USB keyboard scancode definitions.
  • [PR #1224] Allow the compiler to garbage collect USBKeyboard and USBMouse implementations if they are not used in user code, saving flash space.
  • [PR #1225] [Photon/P1/Electron] Combined LEDStatus and LEDCustomStatus into a single class -> LEDStatus

BUG FIXES

  • [PR #1221] [Fixes #1220] [Electron] TIM8 PWM pins (B0, B1) did not work correctly in bootloader with RGB.mirrorTo()
  • [PR #1222] Fixed bug in String(const char* str, int len) constructor when the string is longer than the specified length.
  • [PR #1225] [Photon/P1/Electron] Fixed LED indication shown during device key generation (blinking white) introduced in 0.6.1-rc.1
  • [PR #1226] [Fixes #1181] [Photon/P1/Core] Process TCP DESCRIBE properly and return only one response, SYSTEM, APPLICATION, or COMBINED (ALL) describe message. Was sending separate SYSTEM and APPLICATION previously.
  • [PR #1230] Safe Mode event was being published unconditionally introduced in 0.6.1-rc.1

Firmware 0.6.1 release is out on the Web IDE for Core/Photon/P1/Electron

released on production servers March 1, 2017

:warning: Please Note: The bootloader on Electron/Photon/P1 will update to v11 automatically with this update. Make sure your device is connected to a stable power source and do not remove power until after the device reboots and is running. It happens so quickly right after the device resets and boots that you won’t notice any special RGB LED signaling for this.

Note: This is a Release and may be used for production. Any known issues are likely slated for 0.7.0-rc.1 (check Github issues). It is available by default for all devices. To use, select the 0.6.1 version dropdown from the devices drawer.

Note: If you have previously last used one of the prerelease versions of 0.6.1 on a Core/Photon/P1 device, please re-flash it with 0.6.1. You must upgrade (locally preferred) the Electron system firmware to 0.6.1 first before you can OTA new user apps.

Note: You must update your Electron to (v0.5.3, v0.5.3-rc.2, or v0.5.3-rc.3) first before attempting to use OTA or YModem transfer to update to v0.6.0. If you use DFU over USB, you can update to v0.6.1 directly, but make sure you have installed v1.20.1 of the CLI first.

Note: As a Product in the Console, when flashing a >= 0.6.0 user app, Electrons can now Safe Mode Heal from < 0.5.3 to >= 0.6.0 firmware. This will consume about 500KB of data as it has to transfer two 0.5.3 system parts and three >= 0.6.0 system parts. Devices will not automatically update system firmware if not added as a Product in Console.
