https://devzone.nordicsemi.com/f/nordic-q-a/90328/connection-interval-and-tx-throughputHi, I&#39;m testing maximum tx throughput. I&#39;m using ble_app_hrs example and mcu is nRF52832(s132). (sdk : 16.0.0) The goal is transmit data at 96Kbps. I read that the throughput is related to connection interval and MTU size.

This means that you are not guaranteed to get the connection interval that you desire. You could use the default setting as the ble_app_hrs example.&nbsp;</span></p> <p><span>Data&nbsp;length extension enables the softdevice to overstay the configured event length in sdk_config.h (see NRF_SDH_BLE_GAP_EVENT_LENGTH). Also, see this <a href="https://devzone.nordicsemi.com/f/nordic-q-a/39787/verifying-connection-event-length-extension-and-data-length-extension">post</a>.&nbsp;</span></p> <p><span>Regards,<br />Amanda</span></p><div style="clear:both;"></div>
