Hi,
I just recently managed to make an Arduino Pro Gateway LoRa (a raspberry pi based gateway) work with the Chirpstack Gateway OS. I installed the base version (with the gateway bridge and the packet forwarder) in the gateway, while the network server and the application server are installed in a Ubuntu 18.04 machine. However, the gateway bridge does not receive anything from the packet forwarder. I think it might be a configuration problem, but as I haven’t found any documentation on how to configure the gateway bridge in the gateway, I relied on the information I gathered from this forum.
My configuration files are like that:
Gateway
packet forwarder -> global_conf.json
“gateway_conf”: {
“gateway_ID”: “001bc5067010d02e”,
“server_port_up”: “1700”,
“server_port_down”: “1700”,
“server_address”: “localhost”,
“keepalive_interval”: 10,
“stat_interval”: 30,
“push_timeout_ms”: 100,
“dc_check”:false,
“forward_crc_valid”: true,
“forward_crc_error”: false,
“forward_crc_disabled”: false,
“gps”: {
“type”: “fixed”,
“fixed_alti” : 30,
“fixed_lati” : 45.411718,
“fixed_long” : 11.905840
},
“sock_failure_threshold”: 3,
“sock_auto_rest_threshold”: 3,
“timer_sync”: 30000,
“time_before_radio_write”: 150000
}
gateway bridge -> chirpstack-gateway-bridge.toml
# MQTT integration configuration.

Some useful logs:

Also, when tailing the mosquitto log right after starting the gateway bridge, I can see that the gateway can connect to mosquitto on port 1883, so, the problem is actually in the link between the bridge and the packet forwarder.
Has anyone experienced that? I think I’ve configured everything as I should, or maybe not, so, can someone please help me?
Many thanks,
Níbia
