SLEEP_STATUS
SLEEP_STATUS signal is used to indicate the sleep status of 30 mm × 30 mm LGA
module. The external devices can get to know whether the module is in sleep mode
by reading SLEEP_STATUS pin.

When SLEEP_STATUS pin is in high level, 30 mm × 30 mm LGA modules are in
wakeup state.

When SLEEP_STATUS pin is in low level, 30 mm × 30 mm LGA modules are in
sleep state.
