0x1E Command Packet 1E

Initiate Cold or Factory Reset

This command packet tells the receiver to perform either a cold reset or a factory reset. A cold reset clears all navigation data (for example, almanac, and ephemeris) stored in RAM and is equivalent to a power cycle. A factory reset also restores the factory defaults for all configuration and navigation parameters stored in non-volatile memory. This packet can affect separately the configuration parameters and navigation parameters. It contains one data byte equal to one of the following ASCII letters: ‘K’, ‘F’, ‘C’,‘N’, or ‘R’.

"Caution – The factory reset commands 0x1E-‘F’ and 0x1E-‘R’ will delete the stored position and cause a self-survey to restart. All almanac, ephemeris, current position, mode, and communication port setup information stored in RAM is lost by the execution of these commands.
