additional receiver data and status information.
Table 15: Proprietary Output Messages
NMEA Input Commands
The modules use NMEA proprietary messages for commands and command responses.
This interface provides configuration and control over selected firmware features and
operational properties of the module. Wait time is about 50 to 100 ms.
The format of a command is: $<command-ID>[,<parameters>]*<cr><lf>
Commands are NMEA proprietary format and begin with “$PMTKxxx”.
Parameters, if present, are comma-delimited as specified in the NMEA protocol.
Unless otherwise noted in the Software User Guide, commands are echoed back to the
user after the command is executed.
