I have tried telling 3 times now, that it is NOT possible to have both DTM and ble5-ctr-rpmsg_3310.hex at the same time on the same device. I am sorry if I have been unclear.

Sorry, maybe I didn't make my question clear.

What I want to do is to run nrf5340 audio and DTM on the same device.

Here are my steps:

1.Program DTM firmware
2.Program nrf5340 audio firmware(include ble5-ctr-rpmsg_3310.hex)

Then I got the result:

The device only perform the function of nrf5340 audio.

It's not possible to have both DTM and ble5-ctr-rpmsg_3310.hex at the same time. So you need to re-program the device after DTM.

If I program the device two times, will the DTM of the first program be overwritten when I program the device for the second time?

As shown in the picture, this is the file memory when nrf5340 audio sample is programmed.

And this is the file memory when DTM is programmed.

Their address ranges overlap. When I program the device two times, the device only perform the function of the second application.

Hello,

[quote user="LandyWang"] If I use this method, DTM will be erased in step 3: Program application firmware.[/quote]

That is correct, you can't bundle the two. So you need to program the device two times, one time to execute DTM, and a second time to program the product application.

I am using Programmer Tool to burn firmware. If I use this method, DTM will be erased in step 3: Program application firmware.

Sorry I don't know how to bundle a project with another project at the same time. Are there any documents I can refer to?

I don’t see any other way than;

1. First program DTM project
2. Run DTM
3. Program application firmware

You can bundle the DTM or application project with other tests you want to perform at the same time.

Thank you for your reply.

I read the answers of the issue you provided.

[quote userid="121867" url="~/f/nordic-q-a/98838/how-to-use-nrf-radio-in-nrf5340-audio-sample"]According to this document, nRF radio driver is in network core, is it mean that I only can use NRF RADIO in the sample I build with network core?[/quote]

It seems that this is correct, I can only use NRF RADIO in network core.

Generally, if I want to use DTM mode, I just need to run DTM program in network core and my own project in application core. right?

What I still have doubts about is that when burning nrf5340 audio sample, there is a ble5-ctr-rpmsg_3310.hex that must be burned together with the application firmware to be used. That is to say, it is originally two images.

I guess ble5-ctr-rpmsg_3310.hex is the firmware executed in the network core, although I don't know what its function is. But anyway, if I want to add DTM firmware to nrf5340 audio sample, hex files overlapping issue will definitely happen.

Can DTM mode be used in nrf5340 audio sample?

Hello,

I looked into this about 4months ago, I checked again, and it seems the same answer(s) apply still:
BLE DTM mode on nrf5340
