Firmware 0.8.0-rc.2 Pre-release is out on the Web IDE for Core/Photon/P1/Electron

image

:pencil: Please read all notes in the Notes Festival :tada: below

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.

Upgrading via particle flash --usb or Web IDE (OTA)

No special steps are necessary to upgrade to this release. When using the command-line, simply run the update commands in the correct order, updating system-part1, then system-part2 etc.

From the WebIDE, select the version of system firmware in the devices drawer for your selected device and flash an app to the device. The system firmware will be updated automatically.

Note: P1/Photon: the bootloader must be upgraded using either Serial or OTA update.

Upgrading via particle flash --serial or particle flash <device-id>

When you use YModem or OTA updates to update the device by hand, it’s necessary to follow an upgrade sequence so that the upgrade is successful. If the sequence is not followed, the upgrade will not happen and the version of system firmware will remain unchanged.

Electron

  • first, update to 0.5.3 (if the current version is less than that)
  • then update to 0.6.4 if the current version is less than that)
  • then update to this release, 0.8.0-rc.1.

Photon/P1

  • first, update to 0.7.0-rc.6 first
  • then update to this release, 0.8.0-rc.1

Note about Downgrading [Electron/Photon/P1] OTA or YModem transfer: You should downgrade to 0.6.4 to ensure that the bootloader downgrades automatically. When downgrading to other versions, you will have to manually downgrade the bootloader as well (see release notes in previous 0.7.0-rc.3 release)

Firmware 0.7.0 release is out on the Web IDE for Core/Photon/P1/Electron

released on production servers March 26th, 2018

Note: This is a Release and may be used for production. Any known issues are likely slated for 0.8.0-rc.3 (check Github issues). It is available by default for all devices. To use, select the 0.7.0 version dropdown from the devices drawer. Downgrading back to a previous release info is at the bottom of this post.

Note: If you have previously last used one of the prerelease versions of 0.7.0 on a Core/Photon/P1 device, please re-flash it with 0.7.0. You must upgrade (locally preferred) the Electron system firmware to 0.7.0 first before you can OTA new user apps.

Note: OTA or YModem transfer on Electron (sequence required)

  1. First Update to 0.5.3 (if the current version is less than that)
  2. Then update to 0.6.4 (if the current version is less than that)
  3. Then update to 0.7.0.

Note: DFU over USB on Electron/Photon/P1 (sequence not required)

  • You may update to 0.7.0 directly, but make sure you have installed v1.30.0 of the CLI (check with particle --version) then run particle update.

Note: P1/Photon Bootloader
The cloud will automatically update the bootloader on P1/Photon devices. If your device does not connect to the cloud, you should flash the bootloader to the device using particle flash --serial. This should be done after upgrading system firmware.

Note: Downgrading [Electron/Photon/P1] OTA or YModem transfer:
If you need to downgrade, you must downgrade to 0.6.3(Photon/P1), 0.6.4(Electron) to ensure that the bootloader downgrades automatically. When downgrading to older versions, downgrade to 0.6.3(Photon/P1), 0.6.4(Electron) first, then to an older version such as 0.5.3. You will have to manually downgrade the bootloader as well (see release notes in previous 0.7.0-rc.3 release)

0.8.0-rc.4

ENHANCEMENTS

  • [Electron/Photon/P1] Increase Device OS API argument lengths. More data in Functions, Variables, Publish, Subscribe… oh my! #1537

BUGFIXES

  • [Electron] Particle.keepAlive() API was broken since v0.6.2-rc.2 firmware on Electron where the System would override an early set User ping interval. This required a workaround of updating the keepAlive after the System made a connection to the Cloud. See issue #1482 for workaround. #1536
  • [Electron] Fixes missing URCs for received data during TX or RX socket operations. This caused the modem not to be able to receive further data properly until it re-connected to the Cloud which it would do automatically but usually after a short or longer period of time. #1530

Firmware 0.8.0-rc.14 Pre-release for Core/Photon/P1/Electron

released on January 4th, 2019

:pencil: Please read all notes in the Notes Festival :tada: below

Note: This is a release candidate for 0.8.0 default so please do test on your systems.

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: OTA or YModem transfer on Electron (sequence required)

  1. First Update to 0.5.5 (if the current version is less than that)
  2. Then update to 0.6.4 (if the current version is less than that)
  3. Then update to 0.7.0 (if the current version is less than that)
  4. Then update to 0.8.0-rc.14

Note: DFU over USB on Electron/Photon/P1 (sequence not required)

  • You may update to 0.8.0-rc.14 directly first, flash the system firmware (attached above) in order 1,2(,3) to the device using particle flash --usb <system-part.bin>. See the next note about the bootloader if you are offline!

Note: P1/Photon Bootloader
The Cloud will automatically update the bootloader on P1/Photon devices if your device is online. If your device does not connect to the cloud and it is offline, you should flash the bootloader to the device using particle flash --serial <bootloader.bin>. This should be done after upgrading system firmware. The Electron bootloader is applied automatically from it’s own system parts.

Note: Downgrading [Electron/Photon/P1] OTA or YModem transfer:
If you need to downgrade, you must downgrade to 0.7.0 and then 0.6.3(Photon/P1), 0.6.4(Electron) to ensure that the bootloader downgrades automatically. When downgrading to older versions, downgrade to 0.7.0 first, then 0.6.3(Photon/P1), 0.6.4(Electron), then to an older version such as 0.5.5.

BREAKING CHANGES

  • Beginning with 1.0.0 release, Particle.publish() and Particle.subscribe() methods will require event scope to be specified explicitly. This means using PRIVATE or PUBLIC for Particle.publish() and MY_DEVICES or ALL_DEVICES for Particle.subscribe().

Hi friends!

We just updated release/stable and master branches of the device-os repo to be current with release/v1.0.0.

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 :wink: )

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

Rename the repo to device-os

We also renamed the repo from firmware to device-os and you may update your local clone as follows:

git remote set-url origin git@github.com:particle-iot/device-os.git

Device OS 1.1.0-rc.2 Release Candidate is out on the Web IDE for (Core/Photon/P1/Electron/Argon/Boron/Xenon/Argon-SoM/Boron-SoM/Xenon-SoM)

released on April 30th, 2019


:white_check_mark: This 1.1.0-rc.2 Release Candidate will be defaulted to 1.1.0 on May 14th, 2019 unless there are regressions found that require further patches. :pencil2: Testing on your applications is encouraged and appreciated, thank you! :bowing_man:


Note: This is a Release Candidate (RC) and is not intended for production yet. We’ve tested this RC 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 RC, and be sure to upgrade to the final release when it’s available. This RC 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: OTA or YModem transfer on Electron (sequence required)

  1. First Update to 0.5.5 (if the current version is less than that)
  2. Then update to 0.6.4 (if the current version is less than that)
  3. Then update to 0.7.0 (if the current version is less than that)
  4. Then update to 1.1.0-rc.2

Note: DFU over USB on Electron/Photon/P1 (sequence not required)

  • You may update to 1.1.0-rc.2 directly first, flash the system firmware (attached above) in order 1,2(,3) to the device using particle flash --usb <system-part.bin>. See the next note about the bootloader if you are offline!

Note: P1/Photon Bootloader
The Cloud will automatically update the bootloader on P1/Photon devices if your device is online. If your device does not connect to the cloud and it is offline, you should flash the bootloader to the device using particle flash --serial <bootloader.bin>. This should be done after upgrading system firmware. The Electron bootloader is applied automatically from it’s own system parts.

Note: Argon-SoM/Boron-SoM/Xenon-SoM Bootloader
The bootloader must be manually updated using particle flash --serial <bootloader.bin>. This should be done after upgrading system firmware. Argon/Boron/Xenon bootloader is applied automatically from it’s own system part.

Note: Downgrading [Electron/Photon/P1] OTA or YModem transfer:
If you need to downgrade, you must downgrade to 0.7.0 and then 0.6.3(Photon/P1), 0.6.4(Electron) to ensure that the bootloader downgrades automatically. When downgrading to older versions, downgrade to 0.7.0 first, then 0.6.3(Photon/P1), 0.6.4(Electron), then to an older version such as 0.5.5.
