How to install packet forwarder in chirpstack server installation (IMST iC880A concentrator board)

After installing all components following the documentation https://www.chirpstack.io/guides/debian-ubuntu/, I’ve tried to install packet forwarder. After running compile.sh after making changes, and after running the lora_pkt_fwd file, the following is the output:

pi@raspberrypi:~/Downloads $ cd packet_forwarder/
pi@raspberrypi:~/Downloads/packet_forwarder $ cd lora_pkt_fwd/
pi@raspberrypi:~/Downloads/packet_forwarder/lora_pkt_fwd $ ./lora_pkt_fwd

Before running the packet-forwarder, you must reset it (the Semtech source contains a reset script for this). Make sure the set the correct GPIO pin.

You might be interested in using the ChirpStack Gateway OS image for the Raspberry Pi. That comes with all components + a script for configuration :slight_smile:
