hci0 needs occasioanal reset about bt-mqtt-gateway

[cybe]

This is usually caused by:

• Parallel access to the Bluetooth interface from another process
• Using the RPi Wifi interface in parallel
• Another Bluetooth client accessing the target device, like your smartphone

What bluez version are you using ? For me default version for raspbian was unstable. After updating it works great. I think minimum stable version was 5.49 ( for rpi0 ).

pi@ivanka:~ $ bluetoothd -v 
5.43

followed https://scribles.net/updating-bluez-on-raspberry-pi-5-43-to-5-48/ to upgrade bluez to 5.49.

pi@ivanka:~ $ bluetoothctl -v
bluetoothctl: 5.49

i disabled my reset-cron and will see what happens …

had another bt lock, couldn’t even hciconfig hci0 reset, had unplug-reboot the pi. which bluez version do you use, @zewelor ? sure it’s 5.49?

[zewelor]

Currently I'm using 5.50. Before for many months 5.49.

downgraded back to the built-in raspbian bluez version, which handles sudo hciconfig hci0 reset more gracefully and overall runs more or less stable if i occasionally run the reset command.

@diplix I have the same problems, can you please share the crone job script/config?

i moved bt-gateway to a nuc where it is working reliably. this is what i did on the pi:

sudo crontab -e

20 4 * * * hciconfig hci0 reset
20 10 * * * hciconfig hci0 reset
20 16 * * * hciconfig hci0 reset
20 22 * * * hciconfig hci0 reset

Thanks, I am also on nuc
