Ublox NEO 6M module

  • Protocol: NMEA via UART
  1. Download u-center from ublox
  2. Connect the ublox module to your computer via a USB to Serial converter (3V)
  3. Open u-center, select the correct Receiver COM port: Receiver → Port. If correctly connected, data will now be displayed in the u-center views.
  4. To configure the device, open: View → Configuration View
  5. NAV5 view: dynamic platform model can be set to portable, airborne (50km altitude limit) or pedestrian. Default: portable.
  6. PM view: settings of interest: peak current reduction (p.25 in datasheet), EXTINT pin control high keeps awake.
  7. MSG: DTM off, GBS off, GGA on, GLL off, GRS off, GSA off, GST off, GSV on, RMC off, VTG on, ZDA off
