Two STM32L4 board I2C communication issue, Slave sending the data but master not receiving. can i transmit data from slave to master using this function ? HAL_I2C_Slave_Transmit(&hi2c3, (uint8_t *)Data, strlen(Data), I2C_TIMEOUT);

I have Configured one STM32 board as Master and another is a Slave . When the master send the data slave receiving its fine but when slave sends the data Master not receiving, Acknowledge i am not getting from the Slave when i use HAL_I2C_STATE_READY...
