Constant carrier on nRF Connect Direct Test Mode

[WoutEcto]

Hi,

I previously pointed to nRFgo Studio when the CE/FCC lab wanted to do fixed frequency testing. However I see that now nRF Connect also has a Direct Test Mode application and according to the nRFgo Studio documentation, it is obsolete and nRF Connect is recommended for use with nRF52 series (we are using the nRF52810).

I like the new look of DTM through nRF Connect, but I do seem to miss the 'Constant Carrier' option as packet type. Is this something that is now hidden under other options, or is it not yet implemented?

Regards,

Wout

Constant carrier is not correctly implemented in the current version of the nRFConnect DTM plugin. This should be fixed shortly after the Easter.

Ok, so I can still have the test lab use nRFgo Studio if they need constant carrier? I tested and it should still work with the dtm example code.

Yes, no problem. Constant carrier is always implemented into DTM as a vendor specific command. It's just that the nRFConnect DTM plugin doesn't send the correct command, while nRFgo Studio does.

Since I currently (and urgently) also need this continuous wave mode, I updated the nRF Connect DTM App. Still it seems that CW is not selectable as a packet type?

You can use nRFgo Studio without a problem (https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRFgo-Studio). We successfully got our device through FCC Part 15 testing with it. No changes needed on the firmware side.
