51822 DTM in BQB RF test

[Hailing]

I made a pulse oximeter product with nrf51822AC(base on SDK5.2.0 & S110 6.0.0), and implemented SIG GATT-based profile（PLXP+PLXS). Now we want to do BQB RF PHY testing to test the low energy phy layer of the 51822 which be integrated in pulse oximeter product when whole product runs normally. But this begs the question, though: How can the direct_test_mode example project in SDK and my product software program run together on the 51822 ?

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.

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.
