https://devzone.nordicsemi.com/f/nordic-q-a/67619/gazell-max-throughputHi, I want to know the Max throughput without ack when I use Gazell with air-data-rate of 2Mbps on nrf51 or nrf52.en-USTelligent Community 13Mon, 26 Oct 2020 16:39:44 GMThttps://devzone.nordicsemi.com/thread/276961?ContentTypeID=1Mon, 26 Oct 2020 16:39:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a701fd35-4ee0-4b1c-a1ca-33bb05d01f9eovrebekk<p>Hi</p> <p>There is no way to use Gazell without ACK. The device uses the ACK&#39;s to synchronize with the host, and so they are critical to the protocol working properly.&nbsp;</p> <p>The max throughput with the nRF51 and nRF52 implementation of Gazell is about 213kb/s in each direction, assuming 2Mbps on-air datarate and 32 byte packets.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
