The module supports sleep wake up function. WAKEUP_IN is the host wakeup module,
WAKEUP_OUT is module wakeup host.
Reset: pull this pin down 150-450ms can reset the module, outside the proposed pull-up resistor
10K to VCC_EXT. in module use of an unusual condition or emergency. RESET pin is sensitive
to interference and should be paid attention to it when design.
