Hi,
I'm implementing I2c slave with ESP32. I've looked at the example for I2C slave and I got it mostly working, but problem is that data I receive with i2c_slave_read_buffer is not just i2c - message,but it can contain multiple messages even if I read always the same message size that I use. I'm using my own code on other microcontroller to send the i2c messages and they are always same size.
With Arduino I get callback every time I2c driver has received full message. Is that possible with ESP32-idf and how to do it? Or how to differentiate messages from that buffer I get with i2c_slave_read_buffer? Now I mostly get the correct data,but quite often the data is shifted few bytes and that mess ups the decoding.
