Docker instance never connects to MQTT server #6

Closed danmandle closed 3 years ago

danmandle commented 3 years ago

I have my docker run as follows:

docker run -it --name amridm2mqtt \
--privileged \
-v /dev/bus/usb:/dev/bus/usb \
-e WATCHED_METERS=60162325 \
-e READINGS_PER_HOUR=60 \
-e MQTT_HOST=10.0.0.25 \
amridm2mqtt

When running that command, the following data is shown:

14:44:17.667417 decode.go:45: CenterFreq: 912600155
14:44:17.668354 decode.go:46: SampleRate: 2359296

14:44:17.671150 main.go:119: GainCount: 29

And nothing past there. When I check my MQTT logs, this client doesn't even connect. This is running on a Raspberry Pi 3.

When I follow the run instructions from https://github.com/bemasher/rtlamr, I can see readings coming in.

Ok, some interesting findings...

Note that when running rtlamr directly, the Protocols output is SCM.

Output from rtlamr is SCM unless you specify IDM. I'm pretty sure script is running with command line flags to switch msgtype to IDM 'rtlamr -msgtype=idm -format=csv'

I didn't write settings_docker.py and I'm still running my instance with a venv, so I'm not super familiar... but I think the next thing to try is putting " quotes around the environment variable MQTT_HOST like MQTT_HOST="10.0.0.25"

The other thing is to verify that your MQTT server accepts unauthenticated connections.

danmandle commented 3 years ago

I tired with and without quotes for the MQTT server and have also confirmed that the server does not require creds. I'm going to try another approach. Thanks
