As I am a beginner I followed the I2C_TwoBoards_RestartAdvComIT example from STM32Cube_FW_L4_V1.13.0 . I am able to receive and transmit the data but the control never goes to I2C_SlaveTxCpltCallback() function . So, I am not able to understand that though the data is getting send but the transfer complete callback is not happening.
Every time I get the different command from master and depend on that command slave prepares the response .
