I want to use OTA (or least try to) on my ESP32. I use a SIM7600 to connect to the internet. I am not using TinyGSM for reasons that aren't germaine. I use direct AT command and can connect nicely via HTTP Get to my website for other data and can connect to my OTA bin website successfully. I can see the header contains the correct information about my bin file. I am ready to take the next step to update my ESP32.
All of the libraries I have found so far want a client reference to use and process the gathering of the data in their library (from what I can tell).
How can I supply my response from the bin website and finish the OTA process?
