Description

Is there an existing issue for this?

  • This is a bug in Lakka
  • I have searched the existing issues

Description

Lakka Composite builds for Raspberry Pi 3/4 ... 5?

Bluetooth does not find on-board BT controller

I was first made aware of this from the lakka discord:
https://discord.com/channels/184109094070779904/392140187548909580/1530995360431083540

User was complaining that no BT controllers would pair running pi4 build of composite 6.1

Several steps were recommended including updating pi4 firmware no change in behavior

ultimately recommended trying standard pi4 build and bt was working without issues.

I ran some tests on pi3 and pi4 (i do not have a pi5 with a/v rca jack soldered unfortunately but I suspect that the same is true for that build as well)

both devices i tried gave the same console output when trying to query the bluetooth for devices:

Lakka (official): devel-20260704043020-e6b2de7 (RPi3-Composite.aarch64)
Lakka:~ # bluetoothctl
Waiting to connect to bluetoothd...
Lakka:~ # systemctl start bluetooth
Lakka:~ # bluetoothctl
Agent registered
[bluetoothctl]> show
No default controller available
[bluetoothctl]> 

Expected behavior

when using the standard pi3/4 builds (hdmi out) and i attempt to query bluetooth i get the following output which i am used to seeing:

Lakka (official): devel-20260704042558-e6b2de7 (RPi3.aarch64)
Lakka:~ # bluetoothctl
[NEW] Media /org/bluez/hci0

[bluetoothctl]> 

Steps to reproduce the bug

  1. on fresh flash install of any of the rpi composite builds, enable the bluetooth service
  2. scan for devices
  3. scan eventually times out and shows a truncated word "available"
  4. connect to console via ssh
  5. attempt to run any of the bluetoothctl commands
