I’m trying to get I2C communication between ESP32 and Controllino MINI, using Controllino as Slave.
The little test code I made is working fine when I run it between 2 ESP32’s.
ESP32 is running on 3.3V and controllino on 5V, so I have used a bidirectional logic level converter when connecting ESP32 to Controllino MINI.
I can send data from ESP32 to the MINI without any problem.
When I request data from the MINI, the request is sent to the MINI correctly, but the response does not arrive at the ESP32. (Wire.requestFrom returns 0)
