    Hi Neilh20,

    After some tests and new code I succed with reading PH data from sensor with I2C, and trasmitting them to datalogger over the SDI-12.

    Actually, I must left the slave device in listening mode every time using: mySDI12.forceListen();

    For some reason I didn’t proceed that way… but finally I could find the way 😉

    This is working in AVR MCUs. I have tested in atmega328 (Arduino ProMini 5V-16MHz) and atmega32u4 (Arduino Leonardo).

    I developed the project with VSCode and PlatformIO and Arduino framework, using envirodiy/SDI-12@^2.1.4 library.

    I’m attaching a complete project. I will proceed with new features… 🙂

    I hope the code can help someone else

    Thank you,

    BR,

    daniel
