Device OS 6.2.1 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 Dec 16, 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.

6.2.1

FEATURES

  • Expose ICCID to Modem Manager when tethering #2838
  • [Cellular] BG95-S5 support #2842
  • [BLE] BLE.setAdvertisingScheme() API #2837

ENHANCEMENTS

  • [Gen 4] Optimize QSPI flash writes (to use highest clock speed and IO mode) and erasures (use 32K and 64K blocks when possible) #2841
  • [Ethernet] Minor performance optimizations #2846
  • [Ethernet] Enable internal pull-up on interrupt line in case external one is not populated to prevent it from floating 684047d7
  • [Gen 4] WiFi: Always perform a scan before connect and use both SSID + BSSID to initiate the connection #2849
  • [Cellular] [R510] Extend EHS (Emergency Hardware Shutdown) sequence timing due to reduced clock rate while in (UPSV=1) Power Saving mode #2850

BUGFIXES
