Ok, I could manage to set ISO interval = 20 ms and BN = 2.
The stream still does not work.

Meanwhile I tested a 3rd transmitter (UGREEN-BT701-Source).
This transmitter is also working with the Airoha chipset.

I tried to compare the config.
I see a difference regarding the Advertising Address, nRF5340 send this in the primary advertising packet and the two others in secondary.

I tried to configure sending AdvA in the Secondary packet, but it seems to be controlled by the stack.
Do we have any options?

Best regards,
Tobias

These are set by the controller. The application can try to influence these, but does not have direct control over them.

Hi Amanda,

yes I tried the nRF Auraconfig tool as well.
I tried to set the parameter to the same values as the JBL Go 4 stream:

uart:~$ nac show
BIG 0:
Streaming: true
Advertising name: NRF5340_BROADCASTER
Broadcast name: NRF5340_BROADCASTER
Broadcast ID (random): 0x177aa
Packing: interleaved

BIS 1: nRF_Aura_Config_Audio_Files/10ms/48000hz/80_kbps/right-channel_48kHz_left_80kbps_10ms.lc3 (looping)
uart:~$

Regarding differeces to the JBL Go 4 stream there are 2 parameters:

ISO Interval: 20 ms
BN: 2

With the Auraconfig tool I could not set these parameter to the same value.
Is it possible to modify these parameters?

Best regards,
Tobias

Hi Tobias,

Have you tried the nRF Auraconfig tool? https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/nrf_auraconfig

You can adjust different broadcast parameters in the nRF Auraconfig tool to at least figure out what's not working.

Regards,
Amanda H.
