With the ESP32 I already have OTA working over WIFI. However, I now want to extend to OTA over internet. On my ESP32 board I also have a Quectel BG96 LTE modem and have configured it to connect to the APN of my provider. My question is how I can reconfigure the WIFI OTA to get it working with a UART port of the Quectel modem? In that way I am able to update via the internet!
From what I have seen there is only two ways to have OTA work. One is by using the WiFi access point mode (Which you already have working). The other is using IOTAppStory.
