I need to have the ble server in my stand alone binary. That's why I am not using
bluetoothd plugin. About GATT API, you are probably talking about dbus api to
create custom service instead of using private c API. I am not very familiar
with dbus, I was not able to find a working example of dbus example with bluez5.
I have some delay issue to release my code, that's why I am using c api to gain
some precious time.

I know that bluetoothd cannot run with my custom gatt server. Problem is that
I am not able to set hci friendly name with hciconfig without bluetoothd. So
I have a very dirty way to do it : run bluetoothd few seconds, kill it and then
run my code. Thanks to that I am able to update the hci friendly name (I guess
that some init which are missing in my code are running in bluetoothd)

So your advise is to use btmgmt instead of hciconfig to play with hci device ?

Thanks,
Arthur.
