Latest DTM test for nRF52840

[Hiihtaja]

Hello !

You have DTM test in nRF5_SDK_17.1.0  and in nRF Connect SDK.

I have used SDK test some years ago and it looks more simple if we compare it with new environment,

 

What is real difference between those tests and do I really need new one ?

Also I should customize DTM test for custom FEM and in older it look simple to do it.

Could you explain differences in tests or/and what arguments exist for start usage of new test ?

Regards,

Eugene

Hello,

If I look at the latest DTM that was released in nRF5 SDK I can find that that it was targeted for DTM tests described in BT v5.2:
https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/ble_sdk_app_dtm_serial.html 

So if there have been mandatory tests included in BT 5.3 and later for new BT features, then you may be missing those.

Also it looks like the nRF5340 is not mentioned in the nRF5 SDK, so you can't DTM from nRF5 SDK for that variant.

Also I believe that the FEM support in nRF5 SDK did not include support for the nRF21540 FEM, it may only have included support for a FEM from skyworks, but I may be wrong about this one. I mention it in any case.

But if your main reason for using DTM is to check the hardware and ensure it operates within specification, then there is nothing preventing you from using DTM from nRF5 SDK no.
