I have an arduino and a gps module to be interfaced with RAK811. I would get the GPS coordinates with the GPS module and send it to the gateway through RAK811 wisnode. My question is, would I need to encode my GPS data into hexString payload format before giving it to the RAK811? ( as I have noticed that using the AT command, at+send=lora:1:123456, ‘123456’ is already in the hexString format)?
Moreover, when I received the node data at my RAK7249 gateway, how can I decode it, back to its original data? Btw, i am using the RAK7249 built in server and already change the Decode/Encode format to hexString.
