https://devzone.nordicsemi.com/f/nordic-q-a/44307/nrf51822-maximum-throughput-and-minimum-ber-perDoes anybody know the maximum throughput and minimum BER/PER of nRF51822 at a 1~2 meter distance? Also, when the datasheet says it supports up to 2 Mb/s, is it still with BLE protocol (at 2Mb/s) or does BLE only work up to 1Mb/s? Thanks.en-USTelligent Community 13Tue, 05 Mar 2019 07:25:10 GMThttps://devzone.nordicsemi.com/thread/174142?ContentTypeID=1Tue, 05 Mar 2019 07:25:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:52419f6c-7509-4e6c-ae32-4f43524b7c1aovrebekk<p>Hi&nbsp;</p> <p>Are you looking for throughput when using a BLE stack (SoftDevice), or when running proprietary 2.4GHz communication?</p> <p>The S130 Bluetooth stack is limited to ~150kbps when sending or receiving notifications.&nbsp;</p> <p>When running a proprietary protocol you could theoretically get much closer to the on air bitrate (up to 80% at least), but it requires more work on the software side, and requires Nordic devices on both sides of the link.&nbsp;</p> <p>The 2Mbps mode in the nRF51822 will only work for proprietary protocols. Support for 2Mbps BLE mode was added in the nRF52 series.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
