Page 16 of 35
Revision: V2.0.1-January 2015
Example
The typical average consumption is about 3.5mA in AlwaysLocate
™
standby mode and 3.0mA in AlwaysLocate
™
backup mode.
Power consumption is measured under outdoor static mode with patch antenna. Using external active antenna
will increase the power consumption.
Before entering into periodic backup mode, please ensure the GPS_EN signal is low and power supply for VBAT
is alive.
2.4.6. FLP Mode
The Fitness Low Power (FLP) feature provides low power GPS&Beidou solution for fitness application. FLP is a
duty cycle concept to achieve low power target. It is specifically designed for walking/running/cycling applications.
FLP function is disabled by default. You can enable FLP by SDK or PMTK command. Sending
“$PMTK262,1*29” will enable FLP function, and wait until GT-1612-MTBD module gets a valid fix. Then wait at
least 60s for GT-1612-MTBD to enter FLP mode. FLP function will be disabled after sending “$PMTK262,0*28”.
Table 6: Average Current for FLP Mode and Tracking Mode of GT-1612-MTBD.
The EASY and FLP function cannot work at the same time. When you enable FLP by SDK or PMTK command,
the EASY function will be disabled automatically.
SBAS data downloading will be influenced by FLP function. It is suggested that you should disable the SBAS
while enabling FLP mode.
The power consumption is measured in the open sky under different states of motion.
The current is the average of multiple measurements.
