I'll start with, it used to work and the channel would change properly, but as I've been fiddling with things for reasons I can't understand I've now got stuck on Channel 0 (862Mhz) where I want to use channel 41 (903MHz).

ESP32 all wiring is correct, module responds, other parameters are sent and I have equipment that can measure output so I know I've been able to change the output power from 21dbm to 30dbm, so I know there is communication with the module. Code on the PrintParameters shows the settings I have set. I have tried adjusting PIN_RECOVER to 250mS with no effect. I also note my modules return 0 for model but valid data for the other pieces.

Message is being sent, using sdr module I can see the transmission on 862 MHz (looked at first on 903MHz not found).

Lastly, I have 3 of these modules, they are all currently behaving identically when I swap them out on the perfboard.

Any pointers very welcome, thank you.
