Unsolicited Result Code
^SYSSTART
Indicates that the ME has been started and is ready to operate. If autobauding is active (
=0) the URC is
not generated.
Parameter Description
0
NON-CYCLIC SLEEP mode:
In this mode, the AT interface is not accessible. Consequently, after setting
=0, do not send further characters. Otherwise these characters remain
in the input buffer of the UART and may delay the output of an unsolicited result
code.
The first wakeup event stops power saving and takes the ME back to full func-
tionality level
=1.
[1]
(&F)(P)
Full functionality (no power saving).
If the UART is in one of the CYCLIC SLEEP modes you can issue
=1
to stop power saving and return to full functionality.
Keep in mind that, unlike the reset command described below, the
=1
command does not restart the ME but only changes the level of functionality.
See parameter
for details on the reset.
7
CYCLIC SLEEP mode:
In this mode, the UART is shortly enabled while CTS is active. If characters are
recognized on the UART, the ME stays active for 2 seconds after the last char-
acter was sent or received.
The ME exits SLEEP mode only, if
=1 is entered.
9
CYCLIC SLEEP mode:
In this mode, the UART is shortly enabled while CTS is active. If characters are
recognized on the UART, the ME stays active after the last character was sent
or received for at least the time, which can be configured by
="Pow-
erSaver/Mode9/Timeout",
(temporary wakeup).
In contrast to SLEEP mode 7 assertion of RTS can also be used to temporarily
wake up the ME. In this case too, activity time is at least the time set with
="PowerSaver/Mode9/Timeout",
. RTS can be activated
from ASC0.
The ME exits SLEEP mode only, if
=1 is entered.
The parameter can only be used if the UART is enabled.
Due to the command syntax, you need to enter parameter
, followed by
, where
is only a
placeholder and has no effect. See examples below.
[0]
as stated above.
1
ME resets and restarts to full functionality. After reset and restart, PIN1 authen-
tication is necessary (
).
Notes
•
If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode with
. The
best approach to properly control SLEEP mode in this case is to issue the PSC messages described in
,
Section "Power saving control".
•
While a circuit-switched call is in progress,
=7 or 9 can be activated without terminating the call. How-
ever, setting
=0 during a circuit-switched call immediately disconnects this call.
•
Power saving works properly only when PIN authentication has been done. If you attempt to activate power
saving while the SIM card is not inserted or the PIN is not correctly entered, the selected
level will be
set, though power saving does not take effect. Furthermore, in order to accept incoming calls, SMS or network
related URCs in SLEEP mode the ME must be registered when it enters the SLEEP mode.
