Audio transmission using NRF24L01 module regarding

Hello All

For our project we are using teensy3.6  as our main micro controller unit and NRF24L01 as RF transmission device. 

Our project include mainly  2 parts

1) Data transmission

2)Audio transmission

 

our architecture includes

 

teensy 3.6 : Main micro controller unit

 

SGTL 5000 audio shield: For audio processing and converting sound signal to I2S format.

 

NRF24LF01 : As RF transmission module.

 

In our project we are able to transmit data successfully from transmitter to receiver over NRF module.  But while we tried to transmit audio signal, its fail.

Audio Transmission architecture

We are receiving audio input from a microphone to the SGTL5000 audio shield and converting the audio signal to I2S format by teensy 3.6. Then take the I2S sound format and transmit it through NRF module.  

At the receiver side the NRF module received the signal and hand over to teensy 3.6. teensy will play the I2S signal through SGTL5000.

While doing this we are not receiving the audio signal correctly or the communication not correctly taking place. So we request you to  please guide us to resolve the issue.

 

 

Waiting for your reply.

Thanks in advance
