MESHCORE v1.10 firmware
meshcore_py v2.2.1

I have installed meshcore-py on rpi4 and fedora desktop. When trying to connect via bluetooth. The first connection starts fine pairing finishes, then bluez disconnects. using exemple ble_infos script:

First attempt on rpi4 pairing fine and connection started comes back with looping :

EBUG:bleak.backends.bluezdbus.manager:received D-Bus signal: org.freedesktop.DBus.Properties.PropertiesChanged (/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX): ['org.bluez.Device1', {'Paired': <dbus_fast.signature.Variant ('b', True)>}, []] INFO:meshcore:BLE pairing successful DEBUG:bleak.backends.bluezdbus.manager:received D-Bus signal: org.freedesktop.DBus.Properties.PropertiesChanged (/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/service0028/char0029): ['org.bluez.GattCharacteristic1', {'Notifying': <dbus_fast.signature.Variant ('b', True)>}, []] INFO:meshcore:BLE Connection started DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress DEBUG:bleak.backends.bluezdbus.client:retrying characteristic WriteValue due to InProgress

on fedora it comes back with:

On the second attempt when device is already paired this is the output of the example ble infos script with debugging enabled:
