   sudo /etc/init.d/lora-packet-forwarder-ap2 start(/stop/restart)
   

   • https://github.com/Lora-net/packet_forwarder
   • config file: /var/config/lora-packet-forwarder-ap2/global_conf.json (3/29 changed tx_power to 21)
   • log file: /var/log/lora_ap2.log
2. start chirpstack mqtt forwarder (ap2)

   sudo /etc/init.d/chirpstack-mqtt-forwarder-ap2 start(/stop/restart)
   

   • configuration: /var/config/chirpstack-mqtt-forwarder/ap2/chirpstack-mqtt-forwarder.toml
     • check udp listening on port 1700
     • check/update MQTT server IP, port 1883

        [backend]
        type="semtech_udp"
        [backend.semtech_udp]
        udp_bind = "0.0.0.0:1700"
        ...
        [integration.mqtt.auth.generic]
        # MQTT server (e.g. scheme://host:port where scheme is tcp, ssl or ws)
        server="tcp://MQTT_BROKER_IP:1883"
       

   • check port 1700 binding sudo netstat -anpu | grep 1700
   • log: tail -f -n 100 /var/log/messages |grep chirpstack-mqtt-forwarder
3. (skip: chirpstack gateway bridge)

   Shouldn’t be used on multitech gateways over mqtt forwarder
