"Webb5 jan. 2024 · First the SDA line wasn't low but high. Second, I was using 1k pull-up resistors. So the actually issue was that the resistors prevented the slave or master to drive the line low. I changed them for 2k resistors and it stopped hanging. As an additional safety I added a watchdog to reset the Arduino if the program is hanging. " - I2c lock up recovery

The I2C lines are pulled up by 3.3K ohms. Using REALICE and breakpoints I can see that i2c_write () resets BCLIF and returns FALSE when BCLIF is set.
