Subject to change without prior notice
The following table shows the different operating statuses and how to change them mode:
LED behavior
ME operating status if AT^SSYNC=1
ME operating status if
AT^SSYNC=2
Permanently off
ME is in one of the following modes: - POWER
DOWN mode
AIRPLANE mode
CHARGE ONLY mode
NON-CYCLIC SLEEP mode
CYCLIC SLEEP mode with no temporary wake-up
event in progress (1)
ME is in one of the following modes: -
POWER DOWN mode
AIRPLANE mode
CHARGE ONLY mode
600 ms on / 600ms
off
Limited Network Service: No SIM card inserted,
no PIN entered, network search in progress,
ongoing user authentication or network login in
progress.
Same as for AT^SSYNC=1
75 ms on / 3 s off
IDLE mode: The mobile is registered to the GSM
network (monitoring control channels and user
interactions). No calls are in progress.
Same as for AT^SSYNC=1
75 ms on / 75 ms off
/ 75 ms on / 3 s off
One or more GPRS PDP contexts activated.
Same as for AT^SSYNC=1
500 ms on / 50 ms
off
Packet switched data transfer is in progress.
Same as for AT^SSYNC=1
Permanently on
Depending on type of call: Voice call: Connected
to remote party. Data call: Connected to remote
party or exchange of parameters while setting
up or disconnecting a call.
Same as for AT^SSYNC=1
<n> ms on / <n>
ms off (2)
Not possible: With AT^SSYNC=1, LED
signalization is disabled in SLEEP mode.
SLEEP mode is activated (AT+CFUN
parameter <fun>
≠
1), but the ME is not
registered to the GSM network (e.g. SIM not
inserted or PIN not entered, and therefore,
there’s either no network service or only
Limited Network Service is available.
1) When a temporary wake-up event (for example a call, a URC, a packet switched transfer) occurs in CYCLIC SLEEP mode, the LED
flashes according to the patterns listed above. See Section 2.9.1, Wake up the ME from SLEEP mode, for details on the various SLEEP
modes and wake-up events.
2) The duration of <n> and <m> depends on the network: In SLEEP mode, the module can only change its LED status during
intermittent wake-up periods when listening to paging information from the base station. Therefore the values of <n> and <m> vary as
follows:
<n> = value from 471 ms to 2118 ms
<m> = 3000 ms
4.4. BATTERY OPERATION
MTX-IND-V2 can be ordered with an internal Ion-Li battery. It is 3.7V 1600mA/h and ensures that GSM
module can operate for about 2 hours (periodical GPRS transmission).
