Note that the channel numbers should sequentially match the freqs array in loraModem.h -- e.g. channel 0 should be 903.9MHz (again, assuming US frequencies). If messages are getting to your gateway, but not showing up on your TTN device console, consider changing the _TTNSERVER variable ...
Here is the hookup diagram for connecting the FTDI adapter to the ESP32-CAM module: It is important to note that the FTDI adapter must be set for a 3.3-volt VCC output, not 5-volts, as we are powering the ESP32-CAM using the 3.3-volt power pin. You could also keep the FTDI adap...
