[BUG] bluetooth MIDI controller reconnection.

[rusk911]

Pipedal does not reconnect to bluetooth MIDI controller after startup.

I have a Bluetooth MIDI controller M-VAVE Chocolate. Pipedal is recognizing it only during startup. Then if I switch off and back on bluetooth device, it appears in alsa but not in pipedal. I have to restart pipedald to recognize it again.

• OS: Raspberry Pi OS bookworm Lite
• Linux pipedal 6.12.75+rpt-rpi-v8 Create CODE_OF_CONDUCT.md #1 SMP PREEMPT Debian 1:6.12.75-1+rpt1~bookworm (2026-03-11) aarch64 GNU/Linux
• Raspberry Pi 4B
• PiPedal 1.5.99 Beta

Steps to reproduce:
Switch ON Bluetooth controller.
Switch ON Raspberry PI.
aconnect -l shows
client 128: 'FootCtrl' [type=user,pid=472]
0 'FootCtrl Bluetooth'
Connecting To: 129:0
client 129: 'PiPedal' [type=user,pid=943]
0 'PiPedal:in '
Connected From: 28:0, 14:0, 128:0
PiPedal recognizes MIDI controller and switching presets/snapshot as it should.
Switch off Bluetooth controller.
