Function
Description
Starts BLE service This function makes calls to the GATT and GAP APIs to initialize the BLE service as per parameters stored in the config structure. At the end of this function, one should be able to scan and connect to the ESP32 device using BLE. This API sets the MTU size to 500 (this is not part of the config structure)
