Power Management
When using the GPRS/GSM modem to establish a GPRS/GSM connection (see Chapter
10, Wireless Wide Area Network Configuration ), there are three power conditions that
result in the system or serial driver removing power from the modem asynchronously from
the application.
Low Battery Capacity
After the modem has been powered up, power will be removed from the modem when the
battery reaches a low capacity threshold, before the critical low battery event.
The minimal operating battery capacity values will be kept in a registry key. This value will
be expressed in battery capacity percent.
;
; Minimal Battery Capacity to Allow G18 Operation Expressed in % of capacity
; G18 is shut off when battery capacity falls below this value
