CC2642R: Whether the BLE stack notifies the application when the notification is sent to the client?

BLE notification is an unacknowledged message so you won't be able to confirm message is sent successfully or not.

Hi, Thanks for the reply. I understand that the notification itself is not required to be acknowledged from the client. However, I just want to know if there is a way the peripheral firmware itself BLE stack notifies the higher layer in application yet when the notification is sent?

If so, you can check the return value of GATT_Notification. Returning SUCCESS means it is processed.

Hi,

As per the documentation and comment for "GATT_Notification()", the return value is Success ONLY if the message was queued not sent on the BLE channel actually. So, checking for return value does not help.

Yes but as I know, TI doesn't have API or other way to check if the notification is actually sent.

Hmm. I see. Any other indirect way you can think of then?
