October 21st 2020: Device OS v2.0.0-rc.3

A new Release Candidate Device OS v2.0.0-rc.3 is available now on https://build.particle.io for Photon/P1/Electron/Argon/Boron/B SoM/B5 SoM/Tracker.


Highlights

  • A lot of cellular bugfixes/improvements
  • [Gen 3] SPI MOSI pin drive strength is now set to high by default to support higher frequencies better
  • When going into sleep without specifying network interface as a wake-up source, cloud connection will be properly terminated (allowing session resume on wake-up). When network interface is specified as a wake-up source, we’ll be sending a ping to the cloud on wake-up to make sure that the connection is still alive.
  • In certain cases LED wasn’t going back to blinking green (network connecting) from cyan when the network connection was lost during some initial cloud connection process. This is now fixed.
  • On platforms with PMIC, warm boots will no longer cause occasional modem brownouts due to current limit dropping to 100mA
  • LTE Borons / B SoMs should now be establishing cellular connection much quicker from warm boot (we’ve introduced a workaround for peculiar SARA R410 modem behavior)
  • Some standard C library functions are now exported from the system and are no longer needed to be compiled into the application saving some flash space

Dec 3rd 2020: Device OS v2.0.0 (LTS)

Particle’s first release in our new Long Term Support (LTS) branch for Device OS is now publicly available in the Web IDE, Particle Workbench, Particle CLI, and our Device OS releases page in GitHub. Long Term Support (LTS) releases for Device OS are independent branches of Device OS that are feature-frozen in time, aimed at providing increased stability and reliability for mission critical applications.

To learn more about our new LTS release line, read our latest blog post.

You can view information about Device OS versions, upgrades and downgrades here.

You can view information about Device OS versions, upgrades and downgrades here.


2.0.1

Highlights

  • This release enables a change in product firmware update process from earlier versions of Device OS: Electrons / E Series and Gen 3 devices will receive a bootloader update as a first step without triggering Safe Mode, to ensure that the rest of the update process can benefit from safety enhancements present in the LTS version of the bootloader (#2151 and #2176)
  • OTA updates of Gen 3 devices to this release from Device OS < 1.1.0 no longer require an intermediate update step through Device OS 1.1.0 #2254
  • SystemSleepNetworkFlag::INACTIVE_STANDBY can now be specified when entering HIBERNATE sleep mode to keep the network coprocessor in its current state #2248
  • Fast pin API calls should get some performance improvement compared to Device OS 2.0.0 #2251

You can view information about Device OS versions, upgrades and downgrades here.


3.1.0-rc.1

Highlights

  • [Gen 3] (Argon, Boron, B SoM, B5 SoM, Tracker) maximum application size has been increased from 128KB to 256KB #2322. A few important aspects of this change:
    1. Compatibility with 128KB applications built with < Device OS 3.1 versions is maintained. Devices can still run them even if other parts have been upgraded to Device OS 3.1+.
    2. Upgrade process OTA (including product-based upgrades) is transparent.
    3. When upgrading locally (using DFU or Serial), make sure to update the bootloader first, as it has some logic managing compatibility between 128KB and 256KB application types. See this page on steps how to perform the update.
    4. If using standalone Particle CLI installation, make sure it’s updated to >= 2.12.0 version, which includes support for 256KB applications.
  • A compiler will trigger an error when a function does not return a value, but was declared with a non-void return type #2323
  • GCC 10 support #2288
  • [Gen 3] BLE LE Secure Connections support #2262
  • [Gen 3] BLE LE Long Range/Coded PHY support #2287 #2298 #2321
  • [Boron / B SoM / Electron] SARA R410 05.12 modem firmware support #2317 #2319 #2318
  • APIs to query maximum payload size for cloud primitives #2315
  • Improvements to Argon boot-up times #2327
