#V24 - V24 Output Pins Control
Note: if <state> is omitted the command returns state of the pin.
AT#V24?
Read command returns actual state for all the pins in the format:
#V24: <pin1>,<state1>[<CR><LF>
#V24: <pin2>,<state2>[...]]
where
<pinn> - AT command serial port interface HW pin
<staten> - AT commands serial port interface hardware pin state
AT#V24=?
Test command reports supported range of values for parameters <pin> and <state>.
3.5.5.1.47. Power Saving Mode Ring Indicator - #PSMRI
3.5.5.1.48. Selection of Radio Access Technology - #SRAT
#SRAT – Selection of Radio Access Technology
AT#SRAT=<Act>[,<
PreferredAct>]
Set command is used to set RAT and proffered RAT value used for further network
registration (at+cops=0).
This command forces the selection of the Radio Access Technology (RAT) in the
protocol stack. On a later network registration (+COPS, +CGATT) this RAT is
used. This command is available for phones supporting Dual Mode.
In case of GSM / UMTS Dual Mode is selected additionally a preferred RAT can
be configured, which is stored in NVM selecting which RAT shall be attached first.
#PSMRI – Power Saving Mode Ring Indicator
AT#PSMRI=<n>
Set command enables/disables the Ring Indicator pin response to an URC message
while modem is in power saving mode. If enabled, a negative going pulse is
generated, when URC message for specific event is invoked.
The duration of this pulse is determined by the value of <n>.
Parameter:
<n> - RI enabling
0 - disables RI pin response for URC message(factory default)
50-1150 - enables RI pin response for URC messages.
Note: the behavior for #PSMRI is invoked only when modem is in sleep mode
(AT+CFUN=5 and DTR Off on Main UART)
AT#PSMRI?
Read command reports the duration in ms of the pulse generated, in the format:
#PSMRI: <n>
AT#PSMRI=?
Reports the range of supported values for parameter <n>
Note
When RING signal for incoming call/SMS/socket listen is enabled, the behavior for
#PSMRI will be ignored.
