Throughput testing with nRF5340 and custom BLE code

[Rahaman]

Hello,

I am working with an nRF5340 DUT and I would like to perform a throughput test. I have my own BLE peripheral/central application (developed separately) and I want to measure the throughput of this code.

I see that Nordic provides a throughput test sample in the SDK. My plan is to use the nRF5340 throughput example on one side (DUT), and use my custom BLE application as the peer device instead of running the throughput example on both devices.

Could you please guide me on:

1. Whether this setup is supported/feasible?

2. If yes, what steps or modifications are needed to connect my BLE code with the nRF throughput example?

3. Any recommendations for measuring and logging throughput in this mixed setup?

Thanks in advance.

1. The throughput example uses the GATT throughput service, so if you plan on using the sample on one end, the other device (DUT) also needs to support the GATT throughput service, if it doesn't that isn't the best idea to do throughput tests.

2.You would need to add the GATT throughput service to your project if you want to use the throughput sample.

3. It's also worth noting that we recently released a few other ways to do BLE testing released with the nRF54L express course. It should also work for the nRF5340, but you need to have the Nordic UART service, and advertise very specific data.

Best regards,

Simon
