+CBC - Battery Charge SELINT 0 / 1
Note: although +CBC is an execution command, ETSI 07.07 requires the
Test command to be defined.
AT+CBC=?? Enhanced test command returns the complete range of values for <bcs>
and <bcl>:
+CBC: (0-3),(0-100)
Example AT+CBC
+CBC: 0,75
OK
Note The ME does not make differences between being powered by a battery or
by a power supply on the VBATT pins, so it is not possible to distinguish
between these two cases.
Reference GSM 07.07
+ CBC - Battery Charge
SELINT 2
AT+CBC Execution command returns the current Battery Charge status in the format:
+CBC: <bcs>,<bcl>
where:
<bcs> - battery status
0 - ME is powered by the battery
1 - ME has a battery connected, and charger pin is being powered
2 - ME does not have a battery connected
3 - Recognized power fault, calls inhibited
<bcl> - battery charge level
0 - battery is exhausted, or ME does not have a battery connected
25 - battery charge remained is estimated to be 25%
50 - battery charge remained is estimated to be 50%
75 - battery charge remained is estimated to be 75%
100 - battery is fully charged.
Note: <bcs>=1 indicates that the battery charger supply is inserted and the
battery is being recharged if necessary with it. Supply for ME operations is
taken anyway from VBATT pins.
Note: without battery/power connected on VBATT pins or during a power
fault the unit is not working, therefore values <bcs>=2 and <bcs>=3 will
never appear.
AT+CBC=? Test command returns parameter values supported as a compound value.
+CBC: (0-3),(0-100)
Note: although +CBC is an execution command, ETSI 07.07 requires the
