How to perform DTM test for 52840.

[Mark_Y]

Hi all,

I want to evaluate the performance of BLE. And I use the dtm test example, when I use the cw500 connecting the nRF52840 DK, It always indicates that the EUT connection failed. How should I connect and test. Thanks!

Hi,

Are you using the nRF5 SDK or the NCS SDK?

You could also reach out to R&S as we have little expertise on the CMW500, its likely that there is something with how the CMW500 communications with the nRF52840DK.

I use the nRF5 SKD. If I use the tools that come with Nordic, how am I supposed to send commands. Using serial communication via TX and RX, and who should send the test pack to nRF52840? Thanks!
