FAQ
Why does the first communication fail when the Mini58 served as Slave is woken up through I2C? Issue Date：2018-03-08
Since the time required to wake up the microcontroller (MCU) is longer than the time when the master generates the I2C start signal, while the host sends the I2C start signal for the first time, the slave MCU is still in the wake-up phase. Therefore, the first communication will fail and the second communication will work normally.
