I'm currently using the ESP32 ADC (12 bit) for a fast sampling rate (10-100KHz) to get an accurate signal. The next step is to store this signal, but it will take as size almost 2MB, so I don't know if I can store it in the ESP32 and send it later via BLE (packet by packet), therefore a lot of tasks will end up degrading the process time and Energy.
The main points are :
- Fast sampling rate / accurate signal.
- Sending data to phone with the lowest energy possible.
- using ESP32-S2 to Store 2MB data and resend it to Phone app.
