Raspberry pi does not discover devices

[nigeldun]

Using .Net8. Raspberry Pi running stellarmate. Latest bluez and bluez-firmware installed.

Code that runs fine on Windows 11 finding my device doesn’t discover device when run on the Pi.

Running bluetoothctl on the Pi and doing scan on does report my device along with a number of others. However neither discoverdevice nor discoverdeviceasync report the device though bluetoothctl running at the same time shows the scan.

This is bluetooth classic and the device doesn’t require a pin.

I’ve noticed the bluetoothctl scan can take a while to pickup my device, while a quick look at what i think is the code makes me think that it only allows 5 secs for scan. I have tried running a scan multiple times in the hope it shows up but no luck.
