I am currently trying to get autonomous missions working on my 3.5" FPV quad.
The problem is that even though my GPS is detected, it does not find any satellites (indoors & outdoors) and I get GPS: No Fix.
The GPS I am using is a FlyFishRC M10 Mini GPS module.
I have already tried manually setting GPS_TYPE to u-blox and the baud rate to 115200, as stated in the manual, but without success.
Just to rule it out, I also tried setting GPS_AUTO_CONFIG to "Clear Non-ArduPilot Config", but that did not help either.
Do you guys have any ideas about what I should try next?
Whenever I reflash Betaflight, the GPS module works and finds satellites, so the GPS module itself and the wiring appear to be working.
My 3" has a similar M10 mini GPS module. I find they needed the clearest and most open sky. Mine seems to work well in open areas, but even a few trees and it can take a long time to get a fix. Inside is a no-go, when my regular M10 modules will lock in my basement.
“No Fix” means that it’s detected fine. Parameter changes away from defaults will probably hurt more than help. Let auto-configure do its thing. Wait 15 minutes in a good, clear area before assessing that something is wrong. A brand new module often needs almanac data that is only transmitted every 12.5 minutes. Once received, the necessary data is stored in flash, and subsequent acquisition should be better. But these tiny modules can be a little slow to fix with their small antennas, too.
FWIW, the serial baud rate parameter Is ignored by the u-Blox auto config routine in favor of auto detection.
