uCam III Support

[rony-vargas]

First of all I want to thank you for the hard work done, I started this as University Project, now I am doing more as research/investigation/experimentation side of things.

I am looking through the documentation and I need some guidance on the use of uCAM III library for sending data to your gateway. I see the current documentation but I can't have a clear picture on how to adapt, if you just give me some ideas it will be greatly appreciated.

Regards

I have adapted the code provided in the Arduino Section for LoRa uCamII, removing the XBee parts, and I have made it work until the point it tries to do CAD, but then packets are never sent, here is the output of one run:

Hi, some radio module do have issues with CAD when the radio module is not rebooted appropriately. After flashing the device, try to remove the USB cable, then plug again. If the error persists, try setting uint8_t carrier_sense_method=0; to bypass carrier sense.
