I have a raspberry pi 5 device, with rasbpian (debian bookworm). I bought a chinese led strip, with a bluetooth controller on it, and i would like to connect to it from the pi. Im using bluez 5.66, and with bluetoothctl i can discover the device, and can connect to it, but after a few seconds it is disconnected. With btmon, i can see the logs, and i see that my pi is trying to negotiate the mtu size, but the other device says it is not supported. After 2 tries, the remote device sends a disconnect request.
