Any inputs on this?

Did you remember to advertise? I mean those only services but it
doesn't necessarily advertise which is something perhaps could be
updated on those samples so they become visible on the scanners.

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?

Hello,
I tried cross compiling the bluez and ported it to my linux platform.I
think i have done it correctly as I am able to launch the gatt-service
example successfully but i am not able to view it on the Smartphone
app - blescanner or light blue.

Below are the logs :
===============================================

I also tried to run the python example inside test/example-gatt-server
but again I am not able to view the device name.

Below are the logs :
=======================================
python3 example-gatt-server
example-gatt-server:395: PyGIDeprecationWarning: GObject.timeout_add
is deprecated; use GLib.timeout_add instead
  GObject.timeout_add(5000, self.drain_battery)
example-gatt-server:652: PyGIDeprecationWarning: GObject.MainLoop is
deprecated; use GLib.MainLoop instead
  mainloop = GObject.MainLoop()
Registering GATT application...
GetManagedObjects
GATT application registered

I even opened the btmon on a different tab but still I am not able to
see anything on that.
Is there any other application we have to run?
Has any one ran  it successfully and able to view/connect and see all
the 3 services it is advertising.

Please advise / ask for any further information , I will provide.

Thanks in advance !

Regards,
R
