OTA firmware upgrades over LTE?

  • Hi all,

    I've got the ESP32 Basic Core kit and the COM.LTE module. Just wondering if anyone has has any luck in getting OTA firmware upgrades working over the LTE modem, where the ESP32 pulls the upgrade from web server. All the libraries I have found are for upgrading over wifi. And I have tried various guides that never seem to work, and most others are for pushing an update from a PC to the board.

    Any help would be most appreciated!


  • Hello @aezero

    the linked example works for me. It is using TinyGSM library which supports multiple modems. I've tested it with a SIM7080 modem and CAT-M1.
