10.6 Application Scenarios: System with UART and
WAKEUP_OUT
A host is constructed based on a
single-chip microcomputer
. There is no user interface.
The host supports UART and text messages. After receiving a text message, the host
decodes it and takes corresponding actions.
10.6.1
Hardware Connection
The host must connect to the module using the UART and WAKEUP_OUT pins.
10.6.2
Software Procedure
Command
Description
AT^WAKEUPCFG=?
Query the
parameter
range of
WAKEUPCFG
.
^WAKEUPCFG: (0-1),(0-3),(0-15)
OK
AT^WAKEUPCFG=1,1,2
Configure the module to make sure
that text messages can remotely
wake up the host by WAKEUP_OUT.
OK
AT^CURC=?
Query the parameter
range of
CURC
.
^CURC: (0-2)
OK
AT^CURC=2,800,1FFFFFFFFFFFFFFF
The host wakes up from sleep if the
number of text messages exceeds
the limit.
OK
The host and the module must handshake to prevent data loss when the module
wakes up the host.
