STM32 I2C slave transmit issue

[Chandan Bhatia1]

Hello, I am using STM32 in I2C slave mode. I can able to get data properly but I am unable to transmit. Master is receiving 0xFF all time.

Any stm32 i2c slave code for reference ?

There are examples in the firmware packages downloaded by STM32CubeMX/ IDE or manually downloaded like

STM32Cube/Repository/STM32Cube_FW_F4_V1.24.1/Projects/STM32F4-Discovery/Examples/I2C/I2C_TwoBoards_ComPolling
