In the CC2650DK SimpleBLEPeripheral example, SimpleBLEPeripheral_init() calls
// Register with GAP for HCI/Host messages
GAP_RegisterForMsgs(selfEntity);
// Register for GATT local events and ATT Responses pending for transmission
GATT_RegisterForMsgs(selfEntity);
which allows for SimpleBLEPeripheral_sendAttRsp() and SimpleBLEPeripheral_processGATTMsg() to do some extra processing on HCI and ATT responses. I don't see the same configuration in the HeartRate example. What exactly does this all do? Is it not important enough to be needed in the HeartRate example?
