https://devzone.nordicsemi.com/f/nordic-q-a/18443/benchmarking-bluetooth-5-setup-with-nrf52840Hi, I am looking to test the performance (range, data throughput, packet drop rate etc.) of BT5 in application specific setting using nRF52840. Ideally this would be done by establishing BT5 connection between two PCs, which would be used to controlen-USTelligent Community 13Fri, 16 Dec 2016 12:27:29 GMThttps://devzone.nordicsemi.com/thread/71169?ContentTypeID=1Fri, 16 Dec 2016 12:27:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8dbd963a-21a3-4e85-b3b0-577981b96850Sigurd<p>Hi,</p> <p><strong>Q1</strong>: do I need two of nRF52840 Preview DK to establish point-to-point BT5 communication, or is there a dongle that can emulate one of the devices (master or slave)?</p> <p><strong>A1</strong>: We have not made any nRF52840 dongles yet, so you will need to use 2 nRF52840 Preview DKs.</p> <p>In the SDK 13 we have made an example called <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v13.0.0%2Fble_sdk_app_att_mtu.html&amp;cp=4_0_0_4_2_1_0">ATT_MTU Throughput Example</a> you can use to test both the high data throughput(2Mbps PHY) and the long range feature(coded PHY) introduced with Bluetooth 5. The board that will act as the central is connected to the PC, and you can configure the different parameters of test, monitor the traffic and see the result of the test on the PC using the Virtual COM port(UART) on the PDK.</p><div style="clear:both;"></div>
