Yes, both the lower-tester and the DUT need to use the same RF PHY. I think it should be NRF_RADIO->MODE = RADIO_MODE_MODE_Nrf_250Kbit << RADIO_MODE_MODE_Pos; to set it to 250 Kbit mode. You can also set the m_radio_mode variable to the mode you want to test. Note that regular BLE uses 1Mbit mode.

Sigurd, Thanks for the answer. One additional question, in this post, devzone.nordicsemi.com/.../ a Nordic employee says the following changes need to be made in the DTM example ble_dtm.c --> radio_init() --> NRF_RADIO->MODE = m_radio_mode << RADIO_MODE_MODE_Nrf_250Kbit; Does this change need to be completed on both the DUT running the DTM example and the lower test running the DTM example?

Thanks, Darren

Hi,

If you are using a nRF52-DK as the lower-tester you can use the on-board USB/UART(virtual COM port) bridge that is on the DK.
