Qlg2 Commands - QRP Labs QLG2 Manual

The GPS information display contains five fields as follows:
1. Validity:
A: Valid fix
V: No valid fix is available yet
2. Nature of fix computation
2D: 2-D fix (requires a minimum of 3 satellites)
3D: 3-D fix (requires a minimum of 4 satellites)
3. f (Fix): the number of satellites used in the position fix computation
4. t (Tracking): the number of satellites being tracked
5. s (SNR): The average signal to noise ratio of the satellites being tracked – higher
numbers indicate stronger signal strength

3.13 QLG2 Commands

QLG2 normally converts all incoming serial data from the USB host, converts it to standard
Serial, and transmits this to the GNSS module (or via the TXD interface pin).
However, there are also several commands which you can type into the Terminal Emulator
window on the host PC, as follows:
$$QFU immediately causes QLG2 to restart in the bootloader mode (firmware update)
$$VER returns the current firmware version file name, for example, 1_00.QG2
