from i2s audio to ble streaming

Hi 

i am using the sdk 14.0

i am working with sph0645 i2s microphone , i have tested the microphone and it is working fine with the nrf 52 on 912600 baud rate. Now i wan't to stream that audio via bleutooth to a mobile phone.

The problem is  the 912600 baudrate gives 912600 bits per second and the bleutooth is up to 12200 bit per second,  so the real time streaming is impossible! 

is there a solution to compress the data or any other solution ?
