3.5.3.8. Commands For Battery Charger
3.5.3.8.1. Battery Charge - +CBC
+ CBC - Battery Charge
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
<bcl> - battery charge level(0 ~ 100)
Note: <bcl> indicates battery charge level only if battery is connected and charger
is not connected.
AT+CBC=?
Test command returns parameter values supported as a compound value.
+CBC: (0),(0-100)
Note: although +CBC is an execution command, 3gpp TS 27.007 requires the Test
command to be defined.
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.
