Configuration file to ublox neo M8N (pixhawk)


Does anybody have good configurating file to M8N. And may be somebody have a good tutorial, or can explain , how to load configuration file into u-center, to do some changes and save it again. Or easier way to create that file from zero. 

Already tryied    this one, but half of messages didn't be correctly loaded,because something with versions in u-center

I need only gps logs ubx format file with time,lat,lon,alt,roll,pitch,yaw___and use gps/glonass mode. 

Thanks a lot.

  • The only change that my Ublox Neo-M8N GPS with Compass seems to need is a wire change on the compass plug. I got 10 sats in 29 seconds, but I cannot get a green light on the Pix. The red wire on the compass plug from the HK M8N is in a different place from the 3DR Ublox compass plug. I would like see an official 3DR recommended setup on this before I fry something.

  • You should not actually need to set anything - pixhawk will send initialization commands to the M8N to set the main things such as baudrate each time it boots. There are some settings it may be worth setting through u-Centre, but they really aren't many and I have no idea whether they really make much difference.

  • The default settings should work well, so nothing needs to be changed. If you do change the configuration in u-center then you have to save it with >Receiver>Action>Save Config or it will be erased when you power off. 

    You can change the configuration settings individually with u-center. You can set the dynamic model to airborne in the NAV5 config message. You can limit the messages you get with the configuration settings in u-center if you want only messages that have time, lat, lon, alt. Roll, pitch and yaw won't come from a GNSS module alone, you need sensors for these. GPS/GLONASS mode is set by default, so nothing would need to be changed for this.

    Here's some info from 3DR on how to load a configuration file. The config file they provide is outdated for the M8N. You can make your own file by changing the configurations in u-center that you want, and then using the GPS >> File option to save the set of options to a config file. Then you would load it in as they describe in the tutorial. 

  • why do you need one? i just plugged my M8N to Pix and  it was worked fine w/o any config file....

  • Same for me too.

    I am total new on this :-)

    Thanks in advance.
