+WWKUP
Supporting chipsets:
• MDM6200
• MDM6270 (min f/w rev:
S2.0)
• MSM6290 (min f/w rev:
K_1_1_9ap)
• QSC6270 (min f/w rev:
S2.0)
Enable/disable wake-up signals
Enable (or disable) the output of wake-up signals from the modem to the host device in
response to specific wake-up event types. These settings are persistent (remain
unchanged over a modem power cycle).
• (MSM6290) The modem can send wake-up signals (using the Ring Indicator (RI) on
the Mini Card host interface) to the host when the following events occur: ring
received, radio coverage resolved, and SMS received.
• (MDM6200/MDM6270/QSC6270) WAKE_N pin is used as RI to output the wake-up
signal to the host. Functionality is available even when the UART interface is
disabled.
You must enable the UART interface using !MAPUART=1 for the RI signal to be output.
Signal timing:
• Ring received event—Assert RI for 5.9 seconds, then deassert for 0.1 seconds.
Repeat for number of ring cycles (network dependent).
• Radio coverage restored/SMS received events—Assert RI for 5.9 seconds, then
deassert.
Any wake-up events that occur while RI is being asserted (a wake-up signal is already
being output) are ignored until RI is deasserted.
To identify the event that generated the wake-up signal, see +WGETWK on page 80.
Usage:
• Execution: AT+WWKUP=<bitmask>
Response:
OK
or ERROR
Purpose: Enable or disable reporting of wake-up events.
• Query: AT+WWKUP?
Response:
+WWKUP: <bitmask>
Purpose: Display the current state of wake-up event reporting.
Parameters:
<bitmask> (Wake-up event reporting states)
• 8-bit field (range 00-07)
• Bit values (1=Enable, 0=Disable)
• Bit 0: Ring received (Default = 1). The RING indication on the AT command
port is not affected by this setting—it is still issued even if RI is deasserted.
• Bit 1: Radio coverage restored (Default = 0)
• Bit 2: SMS received (Default = 1)
• Bit 3–7: Reserved (All must be 0)
