Benchmarking Bluetooth 5 setup with nRF52840

Hi,

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 control/monitor traffic and performance.

However, even after reading through Nordic website it still remain slightly unclear on what tools exactly do I need for this. For example, 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)? Or perhaps there is another way?

Also, it is not very clear what software it is needed. Is nRF Connect for desktop sufficient, or would I need to employ one of the IDEs to create a setup for such a BT5 p2p benchmarking? (asking obviously because of the licences)

Thanks!

    A1: We have not made any nRF52840 dongles yet, so you will need to use 2 nRF52840 Preview DKs.

    In the SDK 13 we have made an example called ATT_MTU Throughput Example 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.
