No error occurred when I created a new sketch and compiled as you recommended. I did find where I had removed the previous void loop (because there was no code). I re-entered the void loop command to address that issue. I attempted to compile the updated code an received the following error:

Is 0xae referring to the local or destination that I used for the LoRa addresses in my sketch?
