Isnt ./gatt-service supposed to advertise as well?
I cross built and rant ./advtest with -h and it gave not much information :
./advtest --h
advtest - Advertising testing
Usage:
        advtest [options]

and when I ran
./advtest
it gave : At least 2 controllers are required
what other input does it take ? hci0?hci1?

when i try to run ./advtest -hci0
it gave :  Invalid command line parameters

 i tried to find bt controllers on my board and it gave :

hcitool dev
Devices :

It gave nothing.

Any idea how to proceed ?I suspect I need to enable the hci controller
or something?
But it is strange that ./gatt-service did not throw any error and
registered the services without any error?shouldn't  these examples
check for the ble controller first before proceeding further?
