Bluetooth headphone chip

[Usman Rashid]

Thank you for the support so far.

I want to ask that if for example in your system or product we want to add bluetooth headphone feature which support Bluetooth 4.0 headphones then what one should do in that case?

Consider that in my product we will have two chips one from processing location messages and another for connectivity to Bluetooth headset.

Please recommend me the position solution. For location message processing we are already using NRF52 but for another chip we need recommendation from you.

Hi Usman,

There is no BLE profile for audio as far as I know, definitely not in BT SIG Core v4.0 specification. So I suppose you are looking for combo BT Classic BR/EDR + LE chip. And again as far as I know Nordic don't have any such offer.

Cheers Jan

It is possible (look on any phone or laptop where you have both WiFi and BT and sometime also other technologies like GSM) but it requires good know how about radio/antenna design and compliance (to be able to pass all certifications). Surely two antennas on are interfering with each other, that's why it is so hard to design such things properly. As I said I cannot advice on any BT Classic + LE combo chip.
