I use a lot the NCD products and I have already made a small project where I control various sensors (BME280, MQ135 and LSM9DS0) through the I2C address I found on the documentation.
But when I want to do a master-slave between two nano through the I2C Shield Nano, my communication doesn’t work.
And when I try my two codes (which are really simple) with a direct connection through cable between A4-A4 and A5-A5 it work well
What am I missing ?
Is there a particular address for the communication through NCD I2C cable for the Nano shield (like it is for the BME, MQ, …) ?
Thank you very much for any help
