I am using Hassbian which is a version of Raspbian with Home Assistant installed. I hope posting here is still okay.
I had my Bluetooth radiator thermostat connected to my Pi and everything worked fine. Yeserday I used my Pi to flash a Shelly 1 device over UART. To do that I followed this tutorial. Linked in that article is another older version of the same article.
It tells you to stop and disable the serial-getty@ttyS0.service. I had some trouble because serial0 was not visible for me (solution to that found in this forum: viewtopic.php?t=148713). That is why I tried to follow the old tutorial as well, which tells you to disable a different service.
At this point I had stopped and disabled serial-getty@ttyS0.service and serial-getty@ttyAMA0.service. After applying the aforementioned solution I was able to flash the device and everything worked perfectly fine. But now I am not able to use my bluetooth anymore
I already enabled and started both serial-getty services and reverted both the /boot/cmdline.txt and the /boot/config.txt to their original states but bluetooth just does not seem to work.
In pstree I can see that bluetoothd is running. Restarting it has no effect. Running
Just tells me that no default controller is available. Running
Code: Select all
$ bluetoothctl [bluetooth]# power on bluetoothd... No default controller available
Shows this error message. I am not sure what to do about it because I have already changed the config.txt back to its original state.
Code: Select all
$ bluetoothd D-Bus setup failed: Connection ":1.32" is not allowed to own the service "org.bl uez" due to security policies in the configuration file
I would appreciate every hint and every bit of information
Thank you in advance
PS: This is my complete /boot/config.txt
Code: Select all
