hid_keyboard_example BLE_EVT_TX_COMPLETE

[sam]

Hi,

I'm using ble_app_hids_keyboard example as the base to develop my own application, but was found something really strange, the application seems never get into sleep mode, after doing some traces I found the app contineously generating the BLE_EVT_TX_COMPLETE event, why is that? Since I didn't do anything after application connecting to the iPhone, can this be fixed? I'm using SDK 9.0 and SoftDevice 110, thanks very much..

You will get an BLE_EVT_TX_COMPLETE every time a packet you have queued for transmission using one of the GATTC/GATTS/L2CAP APIs has been successfully transmitted to the peer

I am not expert in HIDS example, if it is queueing packets continuously using gattc_write or hvx or hvc functions, then it is normal to expect this event.

The example is sending battery notifications every 2 seconds and will be waking up periodically to do that. There will also be a BLE_EVT_TX_COMPLETE for every battery notification sent. See the description of the project, infocenter.nordicsemi.com/index.jsp
