⚠️ Caution: After upgrading to 0.5.1, DO NOT downgrade system firmware via OTA remotely

This will cause Wi-Fi credentials to be erased on the Photon and P1. This does not affect the Core or Electron. Feel free to downgrade locally with the understanding that you will have to re-enter Wi-Fi credentials. Also note that 0.5.1 fixes several important bugs, so there should be no reason you'd normally want to downgrade. ⚠️

v0.5.1 Changelog


  • [Electron] Added support in HAL for a SMS received callback handler.
  • Wi-Fi Country Code can be set to configure the available channels and power transmission. #942


  • ARM GCC 5.3.1 compiler support


  • [Photon/P1] Fix a timing-critical bug in WICED that causes system freeze. #877
  • Tone not available on A7 after stop-mode sleep. #938
  • Regression in EEPROM emulation size. #983
  • [Electron] Wrong bitmask is provided for 4208 setting in power management #987
