Audio over Bluetooth
(1/1)
YU7C:
Hi,
I need to transfer full audio signal (16bit 20Hz - 20kHz) from Microphone to Windows PC application over Bluetooth, and have selected Microchip BM62 Wireless module.
At the begining everthing goes flawless: BM62 paired with BT adapter, connected and got BT microphone in Sound.
I got several BT services: Audio Sink, Handsfree Telephony, Headset,...
But audio BW is imited to about 4kHz which told me that only HFP/HSP works, not A2DP.
If I select only A2DP on BM62, then Audio Sink service is only avaliabled but there is no sound from micropne.
I have connected elecret capsule on the microphone input of BM62.
Perhaps I need line input on BM62 for A2DP audio quality signal?
Does anyone has experinces with BM62?
Thanks,
Vojislav

Can I use a line input for audio streaming and A2DP profile?
Thanks,

Ok, but anyway I need only one way path, from the device to PC. If it is not possible have to looking for other solution.
Thanks,

Not only that. A2DP is also compressed, and receiving a2dp is not possible on Windows.
