Connection handler and btmgmt/bluetoothctl

["Clément Jacquemin" <clement.jacquemin@epita.fr>]

Hi,

I am implementing my own GATT server using the "tool/gatt-service.c" as 
example. Create services and read/write characteristics is not a 
problem, but I need a way to track connection and disconnection of clients.
Is there any way to make a handler or callback function that trigger 
when a client connects/disconnects to my server?


Another question about best practice. For the moment I use "btmgmt" to 
configure my daemon. However, the "bluetoothctl" binary seems to be a 
more stable alternative except that i cannot find any way to do the "le 
on" command as in "btmgmt".
Is there any way to activate the low energy option with bluetoothctl?

Regards,

Clément.
