Maximum BLE Throughput on nRF5340 for 1M PHY and 2M PHYhttps://devzone.nordicsemi.com/f/nordic-q-a/124806/maximum-ble-throughput-on-nrf5340-for-1m-phy-and-2m-phyI am working with an nRF5340 device and I want to understand the maximum achievable BLE throughput for both 1M PHY and 2M PHY. Could you please provide guidance on: The theoretical and practical maximum throughput for the nRF5340 on 1M PHY and 2Men-USTelligent Community 13Mon, 06 Oct 2025 13:55:46 GMTRE: Maximum BLE Throughput on nRF5340 for 1M PHY and 2M PHYhttps://devzone.nordicsemi.com/thread/550723?ContentTypeID=1Mon, 06 Oct 2025 13:55:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7929685f-461a-41f3-9803-2cf24713f5b7Einar Thorsrud<p>Hi,</p> <p>The maximum BLE throughput is about 700 kbps for 1 M PHY and 1.4 Mbps for 2M PHY. If you have two nRF5340 DKs you can experiment with the effect of various parameters by using the <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/throughput/README.html">Bluetooth: Throughput</a>&nbsp;sample. The configuration for this sample also serves as an example of a configuration optimized for hight throughput.</p> <p>PS: NovelBits has an excellent guide here describing how to calcualte theoretical throughput with various conditions: <a href="https://novelbits.io/bluetooth-5-speed-maximum-throughput/">Bluetooth 5 speed: How to achieve maximum throughput for your BLE application</a>.</p><div style="clear:both;"></div>
