HTCC-AB02S not joining

#1

Hi there,

I have an HTCC-AB02S running the LoRaWan_OnBoardGPS_Air530 software programmed via Arduino.

I have it configured for OTAA to TTN v3. It is sending join requests, these can be seen on the TTN application dashboard and are being responded to, but the response is not received by the HTCC-AB02S. It just shows “JOINING”

i.e.

TTN seems OK and responding…

What’s really strange is if I use LoRaWAN_OLED it works !!!

Hmm - the serial output still doesn’t look right though

You can check whether it is 530 or 530Z, so that you can choose the correct program to download.
