Hi, have some problem. Have a Beetle esp32 e and have Gravity: Analog Electrical Conductivity Sensor / Meter(K=10) and Analog PH. I can calibrate the PH sensor, but next time i restart the bord its like pH:inf. The ec i not manage to calibrate, just getting >>>Failed,Try Again<<< after my calec command. Some have a solution for this. Also tried theEEPROM cleaning. No resultat. Ideas?

The ads module can help esp32-E read analog values more stably. It is recommended to use with the ads module, please refer to:https://www.dfrobot.com/product-1730.html

Does the sensors work with the ads module on the esp32-E?

When I calibrate the sensors EC and PH on a UNO bord it works, But when a switch back to Beetle esp32 e the calibration dosent work and a cant calibrate on the Beetle esp32 e. So what to do? What is the best card for me to use in this case?
