nRF52840 DK DTM with HEX file

[Ken Li]

Hi,

We want to have some RF-PHY tests on nRF52840 DK.

Therefore, I need a HEX file to make nRF52840 DK get into direct test mode and communicate with CMW270 with UART.

Also, I want to know which pins on nRF52840 DK and baudrate should I use ?

Thanks for your help !

Hi,

You can use the DTM sample for the RF-PHY tests.

Please also refer this ticket which may be of help.

Hi Priyanka,

Thanks for replying, I'm now using nRF Connect SDK v2.3.0.

Should I update SDK to the latest version?

Thanks for replying, I've installed nRF Connect SDK v2.6.1.

The function of DTM works, but the current Tx power is only -1dBm.

How to modify Tx power of nRF52840 DK?

Hi,

You can use the CONFIG_BT_CTLR_TX_PWR to set the Tx power.
