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

Surely it is possible, it's all about details such as how much space you have on PCB, if you can host two 2.4GHz antennas, if you can pass FCC and similar regulations, what communication interfaces you have on the chips and what information you want to exchange etc. Using two BT chips like this looks like completely crazy to me, there must be plenty "combo" chips which can do both BR/EDR and LE.
