I&#39;m trying to send two packets (or 45 Bytes data) in one connection interval. I have made all the necessary changes to increase the att mtu to 247.

You could try to increase the&nbsp;NRF_SDH_BLE_GAP_EVENT_LENGTH to e.g. 320, and see if you are able to send more packets. You can find the&nbsp;NRF_SDH_BLE_GAP_EVENT_LENGTH in sdk_config.h</p><div style="clear:both;"></div>
