51822 DTM in BQB RF test

Yes, the nRF51822 and the S110 v6.0.0 are already qualified so it could sound like you only need to declare your product with the Bluetooth SIG and not qualify it, see this page.

Ok, Bjørn Spockeli. And I have another problem I hope you can help me: I implemented the GATT-based profiles defined by SIG using 51822 and qualified my product as profile subsystem, but the nrf51822 has been certificated earlier, why should I do the RF PHY testing repeatedly in BQB when I didn't modify the RF PHY layer of 51822?

You can only test the RF PHY using the direct test mode which does not use Bluetooth Stack( i.e. SoftDevice). The RF PHY test only tests the BLE radio, not the BLE stack and the profiles that it is running.

Thank you, Bjørn Spockeli. But how can I test the RF performance of the bluetooth module(51822) when it has been Integrated into my pulse oximeter product and the product runs normally? I mean if I flash the direct_test_mode example without my production code when do BQB RF PHY testing, which just test the RF performance of the bluetooth module, not the whole product.

Hi Hailing,

you only need to flashe the direct_test_mode example in order to do BQB RF PHY testing. You do not need to merge the DTM example with your production code.

Best regards

Bjørn
