https://devzone.nordicsemi.com/f/nordic-q-a/2544/throughput-on-nrf51822-usb-dongleDoes anyone have any solid numbers on the maximum throughput achievable on the nRF51822 USB dongle that comes with the nRF51822 Eval Kit? Application - OTA protocol Gazell, three remotes transmitting 108 (data) bytes at each 600us timeslot.

Given the lowest timeslot for 2Mbit on-air data rate, you will see a maximum throughput of: 1000/1.2 * 32 byte * 8 = 213.3 kBit/s</p> <p>Getting through 180 kByte/s (1.44 Mbit) will be very hard in general, as overhead and startup time will have a great impact. You may reach speeds of around 1 Mbit/s if no ACKing is used, and no RF protocol is used (ie: example based upon radio_example in the SDK)</p> <p>Regarding the UART-USB bridge on the SEGGER, we&#39;ve tested 460k baud w/flow control and did not see any corruption.</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
