Problem solved with the latest SDK (2.3.0-rc1) and app version (3330)

Hi Dimitrios,

Thank you for sharing this. I will discuss with the developers and get back to you as soon as I get their response.

I downloaded the latest SDK that was available in Toolchain Manager (2.2.99) and the project successfully compiled. Now, i have the following problem:

I use the default prj.conf (from the nrf5340 audio example application) and add only CONFIG_TRANSPORT_BIS=y

and flash it to the gateway as usual.

Now i try to add the second gateway and add to prj.conf file:

CONFIG_BT_AUDIO_USE_BROADCAST_NAME_ALT=y

CONFIG_BT_AUDIO_BROADCAST_NAME_ALT="sndGw"

and flash it to the second DK.

But, whatever i've tried, i cannot make the headset switch between the two with button 5. I can listen only to one gateway, and gateway alt name for the second board never appears and the sound from the second gateway cannot be listened. The led of the 2 gateways are correct and the blue LED1 is blinking (=they are broadcasting). The led1 on the headset is blinking while connected to the first gateway, but solid blue when i press the button 5. This is what headset gives:

And these are the 2 gateways:

Hi,

What changes did you do in nrf5340_audio_dk_devices.json ? Could you attach the json file?

Also, do you have problems when you try to build / program using command line?

uzer123 — Tue, 31 Jan 2023 15:40:21 GMT

Yes, i used this command:

python buildprog.py -c both -b debug -d both -p -f --pristine

but without pristine it's the same..

This is from scratch try (i only changed the

nrf5340_audio_dk_snr in nrf5340_audio_dk_devices.json) and run the command..Can you replicate it yourself?

Hi,

Have you referred the programming with script?

Could you try just the following if you face error due to readback protection?:

python buildprog.py -c both -b debug -d both -p -f

Do you still get the same errors?

I downloaded the SDK from here. I added to the prj.conf this:

CONFIG_TRANSPORT_BIS=y
CONFIG_BT_AUDIO_USE_BROADCAST_NAME_ALT=y
CONFIG_BT_AUDIO_BROADCAST_NAME_ALT="secondgateway"

I checked src/bluetooth/Kconfig and

BT_AUDIO_BROADCAST_NAME_ALT and

BT_AUDIO_USE_BROADCAST_NAME_ALT

are both included.

And i try this commad:

python buildprog.py -c both -b debug -d both -p -f --pristine

But i get this error:

Any idea?

Yes. It can get a bit messy I understand. Please try manually downloading and let me know in case your issue persists.

Thank you for elaborating that.
I think there is a problem here:

In this file its BT_AUDIO_USE_BROADCAST_NAME_ALT

but in this its BT_USE_AUDIO_BROADCAST_NAME_ALT

Maybe thats why its not working for me

I guess, i can manually download the project folder from github, because the git commands messed my connect SDK.

Hi,

You can find BROADCAST_NAME_ALT in the link.

This is the commit it was added to: https://github.com/nrfconnect/sdk-nrf/commit/9d1a085fee912f2a2226eabe937c7d64751f55bd

uzer123 — Thu, 19 Jan 2023 16:28:13 GMT

i tried that but it didnt worked. I also reinstalled everything from scratch. Shouldn't these options be available in a KConfig file?

RE: nrf5340 audio DK cannot configure BIS mode with two gateways

Priyanka — Wed, 18 Jan 2023 14:36:57 GMT

Have you added the following in prj.conf ?

CONFIG_TRANSPORT_BIS=y

CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT=y

Try adding this and then try the following once again

git stash

git fetch

git checkout main

git pull

git stash pop

west update.

It might show that there is nothing more to fetch and that you are on the correct branch, but just ignore that and then after you have done all this, try building again.

uzer123 — Wed, 18 Jan 2023 11:52:16 GMT

i also use v2.2.0.

In which file is the CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT defined?

For example in this file i can find

CONFIG_TRANSPORT_BIS but not

CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT

RE: nrf5340 audio DK cannot configure BIS mode with two gateways

Priyanka — Wed, 18 Jan 2023 11:40:58 GMT

I has tried replicating your issue and this was how I solved it.

Which nRF Connect SDK version are you trying with?

I had tried with the v2.2.0

RE: nrf5340 audio DK cannot configure BIS mode with two gateways

uzer123 — Wed, 18 Jan 2023 10:08:20 GMT

I tried your steps and I tried to find any differences with the latest repo, but i cant find anything. Here (latest nrf connect sdk version) i can find

CONFIG_TRANSPORT_BIS, but i cannot CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT

Any other step to try?

Hi,

The main was update with some changes. So maybe you are on the old hash. Could you open a command prompt, go to the project location, for eg. cd <your path>\nrf\applications\nrf5340_audio>

Then try the following commands:

git fetch

git checkout main

git pull

west update

Then try building with the Configs enabled in prj.conf

RE: nrf5340 audio DK cannot configure BIS mode with two gateways

uzer123 — Tue, 17 Jan 2023 14:10:00 GMT

I edit the prj.conf and i compile the debug version:

python buildprog.py -c both -b debug -d both -p -f

prj.conf is the default. I just add:

CONFIG_TRANSPORT_BIS=y
CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT=y

If i add only

CONFIG_TRANSPORT_BIS=y

i successfully run the BIS example. So i guess my prj.conf file is working correctly.

Hi,

Are you using the debug version or the release version?

If debug version, then changes should be made in prj.conf and for release version, it should be to prj_release.conf

If your issue persists, could you attach your prj.conf or prj_release.conf here?

Best Regards,

Priyanka
