Hi There,

While reading the data from I2C, I see that the master is missing to send NACK.

Some fixed was done in https://github.com/STMicroelectronics/STM32CubeF4/issues/139 but those fixes are there in the code. But still sometime i see that NACK not being send out and slave pull the SDA line to low.
