I have an Xbee module (XBee ZigBee Module) as an end device. This device is connected to a MCU (STM32F4). The MCU is in the sleep mode when there is no data received from the Xbee module.
So I would like to use an interrupt to wake the MCU up when there is data received by the Xbee module. I am using UART for communication between the MCU and the transceiver.
I would like to know if there is a pin in the Xbee module which can be used as an interrupt to wake the MCU up. Please let me know if you have any idea.
