I want to read a SD12 probe an I am stunned that ESP23 is not supported by the library on github. However I read that a person did get the 1.1.0 version to work ( https://github.com/EnviroDIY/Arduino-SDI-12/issues/47 ) . If this is true I am keen to learn how to do this, can anyone help ? Or any other solutions?
I am not surprised that there is not a ESP32 library for the SDI12, serial, data interface at 1200 baud. Here is the SDI12 data sheet http://sdi-12.org/current_specification/SDI-12_version-1_4-Jan-10-2019.pdf and, using an existing library, you can write your own for the ESP32.
