Error with service startup

[amaisano]

[x] I've read the Troubleshooting Wiki, my problem is not described there and I am already using the specified minimum bluez version.

Describe the bug Manually running sudo ./gateway.py -d works fine and I can see correct output. This is when I try to start the service:

A couple issues here. Looks like the logger cannot load the yaml module. It also says something about start request repeated too quickly.

Probably you don't have required packages installed as root user, or pi user ( depending if you changed service file to run as user )

[harristom]

I have the same issue, also on a Pi Zero. I installed the required packages within the virtual environment following the instructions. I see that service.sh adds the venv to path so theoretically it should work but I suspect the problem lies here somewhere.

[shaaati]

I had the same issue and at least for me, the solution in #194 solved it. Seems like there is a minor mistake in the readme file.

I haven't checked it extensively so far, but at least the service now starts.

[h4de5]

similar problem on rpi0w but starting it within docker. up until now i was not able to get out any logs from the container as it keeps restarting.

[mike0xt]

I had issues getting the service.sh started as well. I had to do #194 by comment out lines 3-9. Before doing that, when executing ./gateway.sh, I ran into btle.py errors, which was fixed with setcap...probably not very secure.

sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/local/lib/python3.7/dist-packages/bluepy/bluepy-helper

I also had to modify the bt-mqtt-gateway.service to add ExecStartPre=/bin/sleep 30 because the service failed to start when system was reboot. Probably needs some python service started first.
