Deadlines on new to Arduino & LoRaWAN - rock & roll!
I’ve edited the code block to format it as per guidelines - please use the </> and never ever post text as an image.
The good news is that the original problem has been solved and your device is now transmitting but is not hearing a response to its Join message. If you’re not clear what that is, read all of this: https://www.thethingsnetwork.org/docs/lorawan/. If you haven’t read all of it already, it’s the fundamentals that you should know and if you don’t, you will find the going very difficult as well as many requests for you to read it.
Do you have a gateway? If not, ouch, where is the nearest one to you? (https://www.thethingsnetwork.org/map/)
If you do have a gateway, what appears in the console when the device tries to Join?
