update ESP firmware (OTA) via connected LTE modem

[zjustin]

Hi Experts

anyone has tried to perform OTA via an LTE modem (like Quectel/SIMCOMM LTE modems) ?

I can only see ways to trigger OTA via WIFI+HTTP, but not seen anything on OTA via modem+http ?

thanks in advance

Justin

Are you using TCP/IP connection through LTE? If so, it should be the same process as wifi OTA.
