The Dagger-QG provides support for specialized hardware features through AT commands. The
features supported include the following.
GPS
The major functionality of the GPS system is to compute the correlation results between the
incoming signal and the selected PRN code based on certain Carrier Doppler Frequency, Code
Doppler Frequency, code phase, carrier phase, and the particular satellite the system is
tracking or acquiring.
GPIO
The GPIO pins are presented to the external environment on the main connector. They
are general purpose bidirectional lines capable of providing system interrupts to
generate a report or drive logic levels to external devices.
LEDs
Two LED status indicators are provided to verify correct installation (Red) and
operation (Green).
