[Qgis-user] QGIS & GPS

Thu Jan 19 22:29:50 PST 2023

Hi Brent,

we solved this for one of our customers with the following steps:

  * Installing U-Center on the windows computer:
    https://www.u-blox.com/en/product/u-center
  * in U-Center -> View -> Configuration view → NMEA (NMEA Protocol)
  * change "Main Talker ID" to "1 – GP(GPS)"
  * click on "SEND" and then on "POLL"
  * now QGIS should directly communicate

hope this helps

Stefan

Mit freundlichen Grüßen
