How to make pairings persistent?

[mkj-stonehill]

I'm using Linux.Bluetooth in a C# program running on a Raspberry Pi 4 (bullseye). I can scan for devices, pair to them, and everything works great...until I reboot; after a reboot, none of my paired devices remain.

If I use bluetoothctl (and scan and pair), the pairings are retained after a reboot.

Is there something I need to do to make pairings persist (i.e. to get restored after a reboot)?

TIA,

Closing, this is not an issue. Please post questions in the discussion board

It looks like you moved it to the Q&A discussion board, which is fine; however, I still have this problem I have to solve. As it stands now, users have to re-scan and pair with the Bluetooth printer after every reboot. Is there any way to make the pairing persistent?

If, from the command line, I run bluetoothctl, and do the following:

scan on
<wait for the printer device to appear>
pair <device address>
trust <device address>
connect <device address>
scan off
exit

Then the device remains paired, even after a reboot. Is there any way to achieve the same from from C# program (using the Linux.Bluetooth package)?

I'm running bullseye (32-bit) on a Raspberry Pi 4.
