Embedded Developer for ESP32 project.

We need to implement transfer of data received from microphones through I2S from ESP32 over Websocket

What we have:

We have implemented and tested the following

1. I2S code - We receive data from I2S microphones to ESP32.

2. Websocket code - The data received from microphone is transmitted over websocket in JSON format.

3. JavaScript Web application - for testing of websocket.

4. OLED display, touch button code

What we need

1. SD card writing code - The data received from microphone needs to be written to SD card attached to ESP32 using MMC protocol.

Purpose of SD card is to provide backup of data acquired in case wireless connection drops

2. File Integrity management - The file saved on the SD card should be the same as the one saved on the other side

3. Integration of different parts of code .

4. Optimisation of performance like task creation, core management and memory management
