Gateway Not Showing Online in ChirpStack Web Interface

[sparkbiit]

I have configured ChirpStack Gateway Bridge and ChirpStack, and I’m able to see MQTT messages indicating that the gateway is connected and publishing stats

Steps Taken

1. Verified the PostgreSQL database contains the necessary tables and the gateway_id is stored correctly.
2. Checked that Redis and PostgreSQL services are running without errors.
3. Confirmed that MQTT messages are being received correctly and contain the expected data.

Request for Help

I would greatly appreciate any help or guidance on why the gateway is not appearing online in the ChirpStack web interface, despite the MQTT messages indicating it is connected and sending data. Thank you in advance for your assistance!

Looks like you might want to replace the au915 with for for example au915_0 (channels 0 - 7), au915_1 (channels 8 - 15), …

Please see for example chirpstack/chirpstack/configuration/region_au915_0.toml at master · chirpstack/chirpstack · GitHub

Perfect, that was indeed the solution! Now I’m in the process of setting up a sensor.
