Bluetooth problem in Trixie 6.12

Hi. I have a problem with image (*.jpg) transfer via bluetooth, on Rex Trixie 6.12 system.

I can pair uConsole with the Android phone (Samsung Galaxy XCover 7 Pro), but phone recognizes uConsole as a headset. I can’t share image via bluetooth.

If I install blueman - I can transfer images from uConsole to phone. But not in other direction…
P.S.: there is some problems to pair phone via blueman, so I paired it with applet that was preinstalled in Trixie.

Can someone help me with that issue?
