Device OS 6.2.0 Release is available in the Web IDE, Particle CLI and Workbench for (Argon/Boron/B-SoM/B5-SoM/Tracker/Tracker-M/E-SoM-X/M-SoM/P2).

Released on Oct 15, 2024

See documentation about Device OS versions, their current state, upgrades and downgrades here.

Gen 3 256KB application binary support

Device OS v3.1.x and further releases bring support for 256KB application binaries to all Gen 3 platforms (at that time: Argon, Boron, B SoM, B5 SoM, Tracker). 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.

6.2.0

BREAKING CHANGES

  • make SYSTEM_THREAD(ENABLED) the default, add deprecation warning on SYSTEM_THREAD() macro use #2834
  • Removed deprecated HAL API wrappers after a set of renamings in Device OS 4.x LTS #2834

FEATURES

  • Extend Particle.publish() and `Particle.subscribe()`` APIs to support events content types #2804
  • Tether API + ModemManager support #2832
  • Supports M.2 breakout board and Muon #2809

ENHANCEMENTS

  • [gen3] make sure that extended system-part1 is compatible with older bootloaders as well as 6.1.2 #2831
  • Improves delay() behavior #2828
  • [photon2] ethernet: use 12.5MHz as the default SPI clock rate for W5500 #2835
  • [Gen 4] Adds detailed WiFi access point disconnect reason logging #2805
