Gatt server service list is empty

I am new to BLE and I am trying to communicate from my android device to my pc running linux using BLE. I have added a service to the gatt server in my android device and I am advertising it. I am getting the server and I am able to access the characteristics inside the service from other android devices using applications like light blue and ble scanner. Howwever, when I am using bluetooth control the service and characteristics are not shown (list-attribute under menu gatt is empty). The bluetooth stack I am using is bluez 5.52.

In order to populate the gatt services you must call discoverServices and let that complete. Once that call completes, then you will have access to your gatt services. I recommend using a library to help you called Android BLE Library, it is from Nordic Semiconductor and really helps out with all the nuances of BLE.
