Thanks for the response.
Would it be possible to support extended periods in receiver mode with the new version?

Regards,
Pawel

Hi Pawel,

Sorry for the late reply.

[quote user=""]Are you planning to revert back the support of Constant Carrier?[/quote]

Constant Carrier mode will be added to DTM sample using 2-wire mode in DRGN-29660: DTM: Add Constant Carrier 2-wire VS commandOpen. We will try to make it in time to backport it to 3.4.1.

[quote user=""]3. I have encountered following SDC assertion when running the receiver mode (it comes from my custom DTM application, which is very similar to nrf/samples/bluetooth/direct_test_mode app. It only replaces twowire_transport with shell over RTT). Would you be so kind to provide some more context regarding this exact assertion? [/quote]

The assertion observed was already fixed in the NCS/main branch and NCS/3.4-branch, so the fix will be available in 3.4.1 when it is released.

Hi Pawel,

We are currently understaffed due to the summer vacation period, so delayed replies must be expected. I am sorry about any inconvenience this might cause. I will update the case once I gather enough information.
