I work on a projects where 2 ESP32 communicate using ESPnow and I want to update both sides using OTA, but can’t get it working. Problem seems to be that I can not set channels in STA mode.
There is some bug/issue with using the CAN driver and OTA together...im not sure exactly what the fix was, something to do with running the CAN driver from IRAM.
edit: oh wait, did you mean "can OTA be used together" or CAN bus and OTA together...?
