        Hi there! Does the Mayfly have an I2C address associated with it? I’m trying to use Wire.h to transmit data between two Mayflys. If it does, where could I find it, for both the 0.5b and the 1.0. Thank you!

          The Mayfly board is not a I2C slave device so it does not have an I2C address.  The easiest way to transfer data between Mayfly boards would be to use UART like serial or NewSoftSerial.

            @zeke-holloman communications – peer2peer – is a deep subject.

            Many years ago I wrote the code for a comms stack to use the 9bit UART to poll an array of processors. In the end it was 2people for 18months to get it working reliably.  So its not trivial, but i had a fantastic time with it.

            It may that you have a special case and only want to use 8bit communications,  it partly depends on what you want to communicate.
