5.4 Mode Power saving control (Power OFF)
It is possible to set the module in power-saving mode with the command
AT+UPSV=<mode>[<time out>].
With the parameter
mode
:
mode = 0
The power-saving mode is inhibited (by default).
mode = 1
The module goes to power-saving mode after expiration of the
time out
. If a character is
received on the
TXD
, the module quits the power-saving mode. Cf §
Erreur ! Source du r
envoi introuvable.
Erreur ! Source du renvoi introuvable.
.
Ex.
AT+UPSV=1
by default the time out is 9.2 s
Ex.
AT+UPSV=1,433
(base time out 4.615 ms) ie 433 x 4.615 = 1998 ms
mode = 2
The module goes to power-saving mode once the
RTS
disappears. The module quits the
power-saving mode once the
RTS
is back. For this mode, the flow control must be inhibited
AT&K0
.
Ex.
AT+UPSV=2
mode = 3
The module goes to power-saving mode once the
DTR
disappears. The module quits the
power-saving mode once the
DTR
is back.
Ex.
AT+UPSV=3
For more information about the AT commands, see the document AT Command List.
The consumption reduction is
40%.
5.5 CTS signal
After powering on the modem, CTS is set on when the modem is ready to operate.
When the GSM module is in Power OFF, the CTS signal does not remain fix. (cf Figure 22 : Status of CTS
Figure 22 : Status of CTS signal
When the module is set in mode 1 (AT+UPSV=1) and is low powered, receiving a character on
the TDX wakes up the module (Power ON) but the character is lost.
The module goes back in low power at the end of the time out setting after receipt of the last
character.
