Is the ble-sniffer application able to capture AUX_SYNC_IND advertisement packages?

[ble_4life]

I try to capture the broadcast packets from the broadcast_audio_source application to investigate the BASE (which holds the configuration of BIGs, subgroups and streams). As I understood the BASE should be inside the AUX_SYNC_IND advertisement packets. But on my recordings with the sniffer I only see AUX_ADV_IND packets from the broadcast device.

I use the nRF52833 as sniffer device. According to nrfutil the ble-sniffer is version 0.13.0.

Hi, 

BIGinfo and BIS are part of Audio which is not supported in the sniffer currently. Although the sniffer can understand the SyncInfo, it would cause an issue while receiving an AUX_SYNC_IND with BIGInfo in the packet. 

If you use periodic_adv sample, you can see the sniffer captures the AUX_SYNC_IND advertisement packets.

Hi Amanda,

just to be on the safe side. If the only purpose I have for the ble-sniffer is to to capture audio related BASE/BIGInfo, then the ble-sniffer can't help me at that point currently?

Unfortunately, not.
