Issue: No Join possible with Antenna Gain 5 setting in global_json.conf
Setup: RAK7243 connected to 5db RAK fiberglass antenna
Packet forwarder 4.0.1 Lora Concentrator HAL 5.0.1
Details: After I lost somehow the connection to my RAK7204 I did a FW upgrade to 22.214.171.124.H.T and tiggered an at+join. Join requests were never accepted. Checking log in TTN I see that the Join request is accepted. Checking the RAK7243 gateway log I see
As I have a 5dB RAK fiberglass antenna connected I changed the value antenna_gain in global_conf.json to 5. Changing the configuration back to 0 the join accept message was after that modification send to the node and the node is now working as before.
Any idea about this error message? Why is a lower RF power not accepted. Is the RAK7243 FW able to handle only certain antenna gain values?
