I2C does not work as a Slave. It just hangs over time

I use standard examples and connect ESP32 to PY32F030 via I2C. I send data and make request, but usually it just hangs during work, only Wire.end(); and restart Wire helps

same issue did you get it?

not much idea. but maybe changing the clock speed may help. I have issue with UART and SPI, but after increase clock speed, it work like a charm. I can drive even 3.5" 240x320 tft display
