CC2650: Connecting a Sensor with CC2650 Launchpad (Multi role BLE example)

Part Number:CC2650

Hi,

I am using the multi-role BLE example and tried to connect 2 CC2650 launchpads. In addition to the existing functionalities in multi-role example, I am trying to interface a sound sensor to one of the GPIO pins and use the sensor data to send a value in GATT write request. Any suggestion on how to integrate this functionality in multi-role example?
