Hello list,
I (again) face problems pairing with a BLE device.
Using bluetoothctl (v5.50), I connected to the device (connect). Then
I try to pair but it fails (org.bluez.Error.AuthenticationCanceled).
The hcidump show a connection timeout.
NB:
- I have a registered agent (although I do not think it is useful in my case)
- I am using Linux Mint 19.1. The same error occurs on a Raspberry Pi
3 with Raspbian.
- I have some bluez distrib packages v5.48 installed. Can this be an issue?
- I got this to work a while ago with the help of someone of bluez on
IRC, doing power off/power on, but this is not working this time...
Thanks

What bluetoothctl says:
[D2A74C76F3E0]# pair D2:A7:4C:76:F3:E0

The corresponding hcidump shows that the connection times out:
