Hi,
I'm working on transmitting audio over BLE. I have successfully connected SPH0645 mic using I2S and also I have connected speakers for the output. The thing is I don't know how to transmit audio over BLE. I tried creating custom template to notify the audio value buffer. Can anyone help me with this. Thanks in advance.

transmit audio over BLE to where? android/windows/....
Does your receiver side have (hardware)BLE5.0 at least?
Here you have the theory, you broadcast the audio stream.

Hi Javier,
I'm transmitting to my laptop. Using python I receive packets in a bytearray. Then I convert those to audio file (.wav).
I managed to notify the data but the data what I'm getting is not the data what I'm sending.

Hello,
You can look FP-AUD-BVLINKWB1 function pack which allows to perform full-duplex voice streaming or stereo music streaming over BLE using the advanced Opus compression algorithm.
Best Regards

Are you sure this is fast enough?
