TX power reduction with bap_broadcast_source

[Axelle]

Hello, 

I'm trying to reduce the range of transmission of the nRF5340 SoC for an Auracast Broadcast. I would like it to be detectable only from a distance of 1 or 2 meters.

I've tried to force the TX_PWR to -20 dB in the configuration menu (west build -t menuconfig), but every time I try to build the project, there are configuring errors :

CMake Error at C:/ncs/v2.8.0/zephyr/cmake/modules/kconfig.cmake:396 (message):

Has anyone encountered this issue and resolved it?

Hi,

Which board do you use?

Do you use bap_broadcast_source sample in NCS v2.8.0?

Can you show your build command?

Best regards,
Dejan

Hi, 

I am working with pan_1783_evb and yes I use  bap_broadcast_source sample in NCS v2.8.0.

My build command is the following : west build -b pan1783_evb/nrf5340/cpuapp

Best regards,

Hi Dejans,

dejans said:

Can you show how you did this? Is your change reflected in the final merged build configuration .conf located in build\zephyr folder? Can you show your .conf file?

I use this command : west build -t menuconfig to get in the configuration menu, then I travel to  Subsystems and OS Services/Bluetooth/Bluetooth Controller/Tx Power : 

Yet even saving the file, I cannot see any difference in the .config file

.

Can you show complete log?

After configuring, even without seing anything in the .config file, I'll have this error log :

Can you clarify this? From which-to-which distance you want it to be detectable?

I would like for the broadcast to be detectable from 0 to 2 meters

Hi Axelle,

We have tested bap_broadcast_source sample in NCS v2.8.0 using nrf5340_audio-dk board. When you successfully build the application. you should have 2 separate images inside build folder. The power change should be done for the image called hci_ipc. The change you make is applied to .config file for hci_ipc image. You need to ensure that you are starting menuconfig for particular image you want, in your case for hci_ipc. After rebuilding (not pristine) your application, you should see the change in the .config file for that image as shown below. We could not replicate the issue when rebuilding failed. 






Best regards,
Dejan

Hello Dejan,

I understand your reply and I indeed wasn't saving the new configuration for the hci_ipc image but for the bap_broadcast_source one. Now that this is done, I still have an error while building with the modifications (not pristine build) : 

Best regards,

Axelle

[dejans]

Hi Axelle,

Are you able to successfully build bap_broadcast_source sample without modifications?

Can you provide full log (instead of partial screenshot) in a separate file and upload it here using Insert -> Image/video/file -> Upload?

Best regards,
Dejan

[Axelle]

Hello Dejans,

I can build it without modifications and even when I change the name of the broadcast or add a password to it. The only modiication I've tried that hasn't work is to force the TX_PWR to -20 dB.

dejans said:

I would like to know which log do you want. The one when i can build the application or the one when I can't ?

Best regards,

Axelle

[dejans]

Hi Axelle,

Try to start from unmodified sample and then only change Tx power using menuconfig and build.  Does the sample build successfully for you?
In our testing, there were no build errors if Tx power was the only change. Did you make any other changes to the sample?

Axelle said:

I am interested in failing log. 
Is the error reproducible on your side? If the error you get is reproducible, please provide all steps that are necessary to reproduce the issue, and I can try to replicate it.

Best regards,
Dejan

Hi Dejans,

Here are the steps I've done so far : 

1. select the bap_broadcast_source sample from NCS v2.8.0
2. build this sample for nRF5340_audio_dk
3. used west build -t menuconfig
4. change the value of TX power to -12
5. saved using Maj+S and modify the path to save it in the hci_ipc image 
6. build (not pristine) the application

Hi Axelle,

Can you provide more details and screenshots for your steps 3, 4 and 5?

Do you see any change when using pristine build?

Best regards,
Dejan

[Axelle]

Hi Dejans,

For step 3 I simply put the command in the termnial,

then I arrive on the configuration menu:

I got in Subsystems and OS Services : 

Then Bluetooth : 

Then I go down to Bluetooth controller which I enable : 

Then for step 4 I go to Tx Power and change the value : 

For step 5, I save the file in the hci_ipc image : 

Best regards,

Axelle

Hi Axelle,

I suspect that the problem might be in the step 5. How have you modified the path and saved the configuration to hci_ipc image?

Best regards,
Dejan
