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

Thanks for the answer but I want to ask that e.g. if in my product there is NRF52 and then another chip just for bluetooth audio so will NRF52 can interfere will the that audio BT chip or what would be the solution in that case ??

Sorry I have limited knowledge on classic BT profiles but you should be more specific when you speak about audio: the usual target is A2DP as specified by BT SIG but you can do many proprietary things including low-quality audio over BT LE 4.x. What are your real requirements? I also have very low knowledge about combo an BT classic chips so I cannot advice about such solutions, maybe someone else will help you on the forum (if you are more specific and accurate in the description;).

Please can you ask someone who can help me?

Basically, our product is a GPS receiver which will calcuate the location based on the RSSI values sent by the beacons.

We also want to add the Bluetooth headphone feature but for that we would need separate IC. Please tell me that is it possible that we can have both NRF52 and Bluetooth audio IC in the same system ??

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.
