Sequans LTE Modem

NOTE: To upgrade to the New Sequans Firmwares 41065 and 41019 you should use the latest Stable release v1.18.2.r4 or the latest Development release v1.20.0.rc9.

Expansion Board

Die New v3.1 Expansion Board Firmware: v0.0.11 | Pycom user forum vom Februar scheint zwar nicht unwichtige Änderungen zu enthalten.

Patch Notes

  • BugFix: Fixed an issue preventing boards from booting when powered via battery.
  • Improvement: Optimised power usage when in deepsleep. down to 32μA

Allerdings kann es hier scheinbar Obstacles geben, siehe Exit from DFU Mode | Pycom user forum. Also Obacht!

Quick how to

Wie man ein Firmware-Upgrade über die command line (Linux, macOS, Windows10) durchführt, ist auch bei [1] beschrieben.
