I’m working through the LoRaWAN Academy using the SODAQ ExpLoRer Board, and I’m having an issue activating the device via OTAA on TTN.
I followed the steps one-by-one and I can’t seem to get the device to join the network. I’ve added the required libraries and uploaded the TTN DeviceInfo sketch to obtain the DevEUI. I then created an application in the TTN Console and I used the DevEUI to register the device to the network.
Then, I uploaded the SendOTAA sketch from the TTN library, ensuring that I changed the loraSerial, debugSerial, and freqPlan parameters to their required values. Prior to uploading the sketch, I then copied the AppEUI and AppKey from the TTN Console and pasted these in the correct area of the sketch.
When I uploaded the sketch, the serial console states:
“Join not accepted: denied Check your coverage, keys and backend status”
I ran the DeviceInfo sketch again and noticed that the AppEUI value had been updated to match the AppEUI from TTN Console.
Any ideas why I am not able to authenticate this device with TTN? Thanks in advance for any help you can provide!
