I use the glib D-Bus interface to connect to a BLE button. This works
great some times but I regularly get this connection error:
GDBus.Error:org.bluez.Error.Failed: Software caused connection abort,
36
The debug output in bluetoothd is:
bluetoothd[17071]: src/device.c:device_set_auto_connect()
80:E4:DA:70:07:A7 auto connect: 1

What worries me is the connect error: Function not implemented (38) line.
I'm on commit 1b9e48f4c2b98ea88e43bd493c098dcca822a1d0
Is this a potential bluez bug?
When I manage to connect to a button, the output is as follows:
bluetoothd[17071]: src/device.c:device_connect_le() Connection attempt

This is coming from bt_io_connect callback so it is very likely this
is from the kernel, check the HCI trace.

This is a different device, are you sure you are testing this
correctly or perhaps only the device 80:E4:DA:70:08:9E is a BLE
peripheral?
