[WICED-SDK-2.2.1]Jason, Is it possible to wake up the MCU by UART interrupt or other GPIO? Customer want to set the MCU to sleep mode and wake up the MCU by UART input. If it is possible, any codes have to be changed for this. The demo shows one timer to wake up the host. Is this the only way to wake up it?
Solved! Go to Solution.

It sounds like you want to configure two wakeups sources when the STM32 is in STOP MODE.These sources are:
- Wake when a WLAN packet is received (this is configured by default via the WLAN out-of-band interrupt)
- Wake on UART activity

The STM32F20x has a WKUP pin on port A0.You could connect to this pin.WICED doesnt have a specific API to set this up yet.
