When you talk about an error, I guess you mean those lines:

<pre>
Sep 25 14:32:25 kalistro bluetoothd[1444]: profiles/sap/server.c:sap_server_register() Sap driver initialization failed.
Sep 25 14:32:25 kalistro bluetoothd[1444]: sap-server: Operation not permitted (1)
</pre>

It seem that this error is harmless. I also have this error on my machine. This is not what's causing your problem.

Apart from those two lines, there's no error in your logs.

Did you try to forget/reset the connection with this device, then retry? Bluetooth is a capricious technology.

From your report, there's nothing we can do to help, sorry.

As arnaudr said, that error is harmless. If you really want it to go away, you can use a systemd drop-in to start bluetoothd without the sap plugin.

This would create such a drop-in:

sudo mkdir /etc/systemd/system/bluetooth.service.d/
echo '[Service]' | sudo tee /etc/systemd/system/bluetooth.service.d/01-disable-sap-plugin.conf
echo 'ExecStart=' | sudo tee /etc/systemd/system/bluetooth.service.d/01-disable-sap-plugin.conf
echo 'ExecStart=/usr/sbin/bluetoothd --noplugin=sap' | sudo tee /etc/systemd/system/bluetooth.service.d/01-disable-sap-plugin.conf

sudo systemctl daemon-reload
sudo systemctl restart bluetooth.service

However, you haven't provided any actual error, so we can't really assist further.

Closing due to lack of response.
Please re-open when ready.
