I do see this but my android device cannot discover the GATT service within the
app. It is possible to pair with it, but not discover the services or even the
device within the app.

I've tired "Bluetooth LE Scanner" and nRF Master Control Panel"

Ivan if you have any success with this could you let me know how you did it?

Thanks,
Kurt
