I would like to ask you for advice. In my project I need to use ESP32 as master and arduino nano as slave. The master will read the values via i2c communication. To give an idea arduino nano (slave) will be 3-9 pieces as needed.
For your convenience, I enclose the master and slave code. For example, if I use arduino uno (master) and arduino nano (slave) the code works. If I use ESP32 as master code it does not work … Esp32 sends a signal, arduino nano receives a signal and sends values, but ESP32 no longer accepts / reads values …
I read about similar issues on this forum but bokužel nothing helped. I also tried logic level converters but also nothing.
Thank you in advance for your reply
