### Creating a bug report/issue
I have searched the existing open and closed issues
#### Required Information
- DietPi version | G\_DIETPI\_VERSION\_CORE=9
G\_DIETPI\_VERSION\_SUB=11
G\_DIETPI\_VERSION\_RC=2
G\_GITBRANCH=‘master’
G\_GITOWNER=‘MichaIng’
- Distro version | bookworm
- Kernel version | Linux Opi5 6.1.84-vendor-rk35xx #1 SMP Sun Jan 5 09:09:31 UTC 2025 aarch64 GNU/Linux
- Architecture | arm64
- SBC model | Orange Pi 5 Max (aarch64)
- Power supply used | 5V 4A
- SD card used | Crucial P5 Plus NVME
#### Steps to reproduce
dietpi-config → Advanced options → Bluetooth [ON]
sudo bluetoothctl
show
#### Expected behaviour
Display BT controller info
#### Actual behaviour
Was seeing “no default controller”
Tried various tweaks found by searching for similar reports, now am seeing:
Waiting to connect to bluetoothd…
#### Extra details
Originally had serial ports disabled, then enabled (ttyS7)
And changed /dev/ttyBT0 to /dev/ttyS7 in sprd-bluetooth.service
since `ls /dev/tty*` did not list ttyBT0
So the missing ttyBT0 is probably root cause, but not sure why it’s not there.
Any help greatly appreciated

kernel patch maybe?

The chipset is the ap6611

so who knows if the stock kernel has the drivers for that particular chipset…or if they need to be built and then modprobed in at boot

Maybe build a DKMS automatic module build when kernels get upgraded
Lol…I used duck.ai to generate a convoluted “howto”
Do not follow this simple and incorrect…but it get’s you in the “ballpark” I guess

Thanks for info. Yes ap6611 is chip, mentioned in dmesg so something is loaded – wifi is working.
BT is not critical for my needs, but would like to get it working. Not sure if I am ready to patch the kernel, the board+dietpi is working really well 😛
Thanks for your advise, I may pursue that if I get more adventurous.
