i’m using the WiFi LoRa (ESP) 32 V2 in my University project and i would like to make this board act as a Slave in a I²C communication with a Raspberry Pi
In this site I found an example of a I²C between a Raspberry Pi (Master) and an Arduíno ( Slave) and I would like to do exactly the same (changing the Arduino to an Esp LoRa) .
I’ve managed to do this with a Raspberry and a regular ESP 32 too and it worked just fine. However, I don’t know why it is not working on this board. I’ve read that the board has 2 I²C bus lines and this may be the problem.
Can you please help me? Thank you very much for your attention,
