For one of the pieces of software for one of the pieces of software we would like to ship that I’m working on containerising has to access parts of the host system using dbus to access bluetooth and wi-fi. I’ve allowed dbus access via the dockerfiles but that still didn’t work. For Raspbian the software states to copy a configuration xml to /etc/dbus-1/system.d/ which didn’t do anything when I copied it in the container. As a final resort I then remounted the host OS as write and created this XML config file on the host os and the software is now working. So it seems that this configuration file is required to be on the host, however there isn’t a recommended method of modifying the Host OS from what I can find. Is there a recommended way to possibly do this or a workaround that can be suggested? Thanks ---

Therefore, I want to edit /etc/dbus-1/system.d/org.freedesktop.NetworkManager.conf of host OS, but I can not do it because it is a read-only file system. And I want to do the editing from inside the container.

I take a look around the forum but can’t find an idea (I don’t know the Bluetooth protocol very well). From my understanding : bluetoothd communicate with the Bluetooth device and run on the BalenaOS host and them the container communicate with the daemon through dbus with an agent (bluetoothctl for example). I can pair my device but can’t connect it. I try to adapt what was done in the Bluetooth BalenaSo…
