The onDataSent callback function is never called

It seems the onDataSent callback is supposed to be called when a notify characteristic is sent and a GATT_EVENT_DATA_SENT event is generated. But, in the BLE stack, sending a notify characteristic only generates a BLE_EVT_TX_COMPLETE event (int the ble.h).

The onDataSent callback and the GATT_EVENT_DATA_SENT event are in the GATT layer, but the BLE_EVT_TX_COMPLETE event is not. How to correlate the BLE_EVT_TX_COMPLETE event with the GATT_EVENT_DATA_SENT event?

The latest version of BLE_API and nRF51822 libraries address this issue and allow for the propagation of onDataSent().

Thanks for bringing this issue to our attention.

regards, Rohit.
