Pull Request Description: Add Support for Quectel-specific NMEA Sentences in
pynmea2Description
This PR introduces support for Quectel-specific NMEA sentences by adding new proprietary sentence classes under the
QTMnamespace. These classes enable parsing and handling of device-specific messages, such as GNSS status, configuration settings, geofencing, and more. This extends the library's capabilities for devices like Quectel's LC29H GNSS module.Changes Introduced
New Classes:
QTM: Base class for Quectel proprietary sentences.QTMVERNO: GNSS module version information.QTMSAVEPAR: Save receiver parameters.QTMRESTOREPAR: Restore receiver parameters.QTMEPE: Outputs estimated positioning error.QTMCFGGEOFENCE: Configure geofences.QTMGEOFENCESTATUS: Geofence status.QTMCFGSVIN: Survey-in mode configuration.QTMSVINSTATUS: Survey-in status.QTMCFGRCVRMODE: Receiver mode configuration.QTMDOP: DOP values for GNSS accuracy.QTMPL: GNSS protection levels.QTMCFGSBAS: SBAS configuration.QTMCFGCNST: GNSS constellation configuration.QTMCFGFIXRATE: Configure GNSS fix rate.QTMVEL: Velocity information.QTMCFGODO: Configure the odometer feature.QTMODO: Odometer status.Tests Added:
tests/test_qtm.py.How it Works
QTMbase class dynamically assigns the appropriate subclass based on the first data element (manufacturer + data[0]).build_date,epe_north,geofence state, and others.__repr__implementations for better debugging and logging outputs.Checklist
