Steps to reproduce

dietpi-config / Advanced Options / Bluetooth set from Off to On then restart
bluetoothctl

Expected behaviour

Agent registered
[bluetooth]

Actual behaviour

after bluetoothctl is showing only Waiting to connect to bluetoothd....

Extra details

everything was done under root user

journalctl -u bluetooth
It showed: configurationDirectory 'bluetooth' already exists but the mode is different. (File system: 755 ConfigurationDirectoryMode: 555)

Used:
sudo chmod 555 /etc/bluetooth
sudo systemctl restart bluetooth
it fixed the issue until next reboot now journalctl -u bluetooth showing:
Oct 06 10:51:17 DietPi systemd[1]: bluetooth.service - Bluetooth service was skipped because of an unmet
condition check (ConditionPathIsDirectory=/sys/class/bluetooth).

fixed by commenting ConditionPathIsDirectory=/sys/class/bluetooth in /etc/systemd/system/bluetooth.target.wants/bluetooth.service

2nd issue until restart and now:
scan on
No default controller available

hciconfig -a
hciconfig hci0 up
Can't get device info: No such device
hciconfig hci0 reset
Can't get device info: No such device

current status of "journalctl -u bluetooth":

Can you check the hciuart service logs?

journalctl -u hciuart

Strange, that service is forcefully started and enabled when enabling Bluetooth on RPi via dietpi-config. Does this work?

systemctl enable --now hciuart
sleep 2
journalctl -u hciuart

The required secondary serial device is missing. Can you check the following:

ls -l /dev/{ttyAMA0,ttyS0,serial0,serial1}

Rhiz3K · 2023-10-07T18:21:16Z

ls -l /dev/{ttyAMA0,ttyS0,serial0,serial1}
ls: cannot access '/dev/serial0': No such file or directory
ls: cannot access '/dev/serial1': No such file or directory
crw-rw---- 1 root dialout 204, 64 Oct 7 11:31 /dev/ttyAMA0
crw-rw---- 1 root dialout 4, 64 Oct 7 11:31 /dev/ttyS0

I can replicate the issue of the missing serial0/serial1 symlinks. Currently investigating the reason for this.

@Rhiz3K

- Raspberry Pi | Resolved an issue where the /dev/serial* symlinks were missing if binutils was not installed, which broke Bluetooth support among other things. Many thanks to @Rhiz3K for reporting this issue: #6666

MichaIng · 2023-10-08T13:57:48Z

Fixed with: 0812ad7

Please do this:

curl -fo package.deb 'https://dietpi.com/downloads/binaries/raspberrypi-sys-mods.deb'
dpkg -i --force-confdef,confold package.deb
rm package.deb
reboot
