3.5.7.1.39 TTY-CTM-DSP Operating Mode - #TXMONMODE
#TXMONMODE- TTY-CTM-DSP Operating Mode SELINT 2
AT#TXMONMODE=
<mode> Set TXMON pin behaviour.
Parameter:
<mode>
0 - TXMON pin goes high when a call is started and it drops down when
the call is ended. It also goes high when a location update starts, and it
drops down when the location update procedure stops. Finally it goes
high during SMS transmission and receiving. Even if the TXMON in this
case is set as GPIO in output, the read command AT#GPIO=5,2 returns
#GPIO:2,0, as the GPIO is in alternate mode.
1 - TXMON is set in alternate mode and the Timer unit controls its state.
TXMON goes high 200 μs before TXEN goes high. Then power ramps
start raising and there is the burst transmission. Finally TXMON drops
down 47
μs after power ramps stop falling down. This behaviour is
repeated for every transmission burst.
Note: if user sets GPIO 5 as input or output the TXMON does not follow the
above behaviour.
Note: if <mode> is change during a call from 1 to 0, TXMON goes down. If
it is restored to 1, TXMON behaves as usual, following the bursts.
Note: this command is not supported in GM862 product family.
AT#TXMONMODE? Read command reports the <mode> parameter set value, in the format:
#TXMONMODE: <mode>
AT#TXMONMODE=? Test command reports the supported values for <mode> parameter.
3.5.7.1.40 Battery And Charger Status - #CBC
#CBC- Battery And Charger Status SELINT 0 / 1
AT#CBC Execution command returns the current Battery and Charger state in the
format:
#CBC: <ChargerState>,<BatteryVoltage>
where:
<ChargerState> - battery charger state
0 - charger not connected
1 - charger connected and charging
2 - charger connected and charge completed
<BatteryVoltage> - battery voltage in units of ten millivolts: it is the real
battery voltage only if charger is not connected; if the charger is
connected this value depends on the charger voltage.
