Ublox neo M8N with quanton

by brat002 » Sat Mar 14, 2015 2:13 pm

Hi all.

Today i got Ublox neo M8N and trying to connect it to quanton with last Taulabs firmware.
I select UART port for gps, connect wires and now GPS button in Flight Data tab is red(gps is recieving data but no fix). I tried many times in door and outdoor bot GPS button still red.

GPS module must be configured manually or what is my mistake?

Thx

Sounds like it is working and most likely will not acquire all the sats needed if indoors unless it has a very good antenna on it. It takes some time to acquire them the first time and also if the on board battery has run down.

To answer your question go to system>settings>module settings>gps auto configure and set to false. Then click and highlight Module Settings and click on red upload arrow.

The M8 I used would not give sat count until it had acquired enough sats and it also did not show sat signal strength but did work on AutoConfig. I have switched back to using LEA-6H for now.

Maybe you can share the configuration file that you used when you said it got a fix? Then we can see what is different between that and autoconfig.

However, I would definitely see what happens with autoconfig outdoors. That sets up a number of things that have been widely tested and seem to work quite well. I don't have any manual configs because I always use autoconfig.
