Subject: Bluetooth: Unknown BR/EDR signaling command 0x16 / Wrong link type (-22) on meson-gx / Banana Pi M2 Pro

Description: When connecting modern Android (POCO F7) and Windows/Linux devices (Lenovo Legion) via Bluetooth to Banana Pi M2 Pro, the dmesg log gets flooded with BR/EDR signaling errors during connection/disconnection phases.

Steps taken: - Forced 'ControllerMode = bredr' in /etc/bluetooth/main.conf - Disabled USB autosuspend for the BT controller (set to -1)

Logs: [ 345.122975] Bluetooth: Unknown BR/EDR signaling command 0x16 [ 345.123005] Bluetooth: Wrong link type (-22)

Environment: - Board: Banana Pi M2 Pro (Amlogic S905X3) - Kernel version: 6.18.34-current-meson64

nano armbianEnv.txt

extraargs=usbcore.autosuspend=-1

The problem with Bluetooth on bananapim2pro is that I constantly have trouble connecting. My tweaks to the settings fixed it somewhat, but not 100%... Finally, if all else fails, I use this method:

sudo rmmod btusb
sudo modprobe btusb
sudo systemctl restart bluetooth
sudo systemctl restart bluealsa

But I have a question: are there any kernel/driver fixes or updates for this Bluetooth model?
