    What sketch are you running?  The debug statements above are mentioning Digi Xbee module, but your photo shows a Simcom SIM7080 module.  The code for a Digi Xbee modem is not compatible with the Simcom module shown in the photo.

    If you’re trying to use the configuration shown in the photo, along with a Hyrdos 21 CTD sensor (as indicated in your code above) then you should be using the example sketch we wrote for this exact configuration:  https://github.com/EnviroDIY/ModularSensors/tree/master/examples/DRWI_Mayfly1
