Hi Karl, your message made me curious, so I looked in the python script.
First of all, I think you do not need gpsbabel at all. Because your GPS-Mous already provides NMEA, i.e. what QMS needs A simple cat /dev/ttyACM0 might do the job as well. Regarding the python script: It looks like it is doing two jobs a) set all GPS fixes to valid (probably contradictory to your goals?) b) ensure that timestamps contain fractions of seconds (apparently needed by QMS) With a bit of luck, the timestamps provided by the GPS mouse already contain sub-second fractions. Then you could cat directly to nc Otherwise, you might comment out that line of the python script msg.data[idx["gps_qual"]] = '1' Have fun, Helmut Am 11.10.2020 um 18:08 schrieb Karl Karsten: > Hello all, > > I bought at Amazon this little GPS-Mouse (Stick G72 USB GPS-Mouse) and > plugged it to my Tablet. > > > https://www.amazon.de/gp/product/B07SMRXSC8/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8 > > More or less it's working out of the box.
