How do I switch BLE service off?

Hi All,

BLE does not work on my rpi5. It gives D-bus errors…
With systemctl disable it does not work… also restart=no in the .serve file does not work…

So… how doe I switch it off?

Cheers,

Maarten

Hi Riban,

I think the Bluetooth install is not as it is intended… A library is missing when I try to re-install.
After re-installing this lib and re-installing Bluetooth, Bluetooth MIDI works OK :slight_smile:
So →

Re-install bluetooth

sudo apt -y install python3-docutils
/zynthian/zynthian-sys/scripts/recipes/install_bluez.sh

Cheers,

Maarten

I also get a Bluetooth error message.

Thanks to your instructions, I could deactivate Bluetooth.

Of course it would be better if it could be repaired.

Maybe there will be an update.

root@zynthian://zynthian# sudo service bluetooth status :

Sorry, I still get the bluetooth error when I activate it.

This is recorded as issue 1214. I will take a look when I get a moment.

FYI: Bluetooth management was modified in Oram and tested against a small but varied range of devices. It is plausible that I installed or compiled dependancies on the test machine that didn’t get caught by the update mechanism. I will check with a freshly imaged machine and work through the issues. The suggested solution does not look familiar to me so maybe it installs a library or other dependancy that is required. We do not use the standard Debian Bluetooth applications as they are missing some important elements that we have added, specifically direct integration with jackd. Manually installing applications or libs may interfere with zynthian’s normal operation.
