Support Request: The Bot does not get triggered despite being connected to BLE

[Lazza]

Describe Your Problem

I am trying to activate a SwitchBot Bot via Homebridge. The device is connected correctly via BLE and shows the battery level (it seems). Nevertheless, when triggering the Bot, nothing is performed.

Relevant log output

Finally, after days of trying I solved the issue.

This is due to the configuration of the host system (not the Docker container).

According to this Stack Overflow answer, one has to disable a plugin called pnat. This is done by adding the following line at the bottom of /etc/bluetooth/main.conf:

DisablePlugins=pnat

After doing this and restarting the bluetooth service, everything is working perfectly.

how can we edit the file? with filezilla i can't. it says i have no root access

You can connect via SSH and use sudo to gain root access, then edit the file with nano.
