Hi
We are working on a product which uses the CYBT-343026-01 module from cypress which supports BT + BLE coexistence.

Our use case involve using Classic Bluetooth connection with A2DP profile for audio streaming from mobile app to our device , BLE peripheral having some services and characteristics for data exchange between Mobile BLE App and our device and BLE scanner for scanning Non Connectable data packets(Beacon Data) from another BLE accessory.

We are able to establish the audio streaming with the Mobile phone and also connect to the BLE App on the mobile phone and interact with the App while the audio is playing without any packet loss.
Hence BLE services and Classic bluetooth as media device for audio streaming is visible in smartphone and able to connect smartphone to the device for both BLE and Classic bluetooth.However, the issue we see is that our device is not able to receive any Beacon data when audio streaming is going on and when audio streaming is paused the beacon data is received by our device.We also tried to stop the ble advertisement when a2dp streaming is on to solve this issue but didn't see any difference.

How can we ensure the chip receive the BLE beacon data while audio streaming is active ? Is there any additional command or state that needs to be set for the chip to function in this condition.

Hi PrU_4445086 ,

Sorry for keeping you wait.
Seems like this is a limitation on our chip. You have to pause the streaming to get BLE scan working.

If this is a critical requirement , I would suggest you to contact our local FAE for evaluating the feature request.

Thanks & Regards,

Anjana
