Ublox m8n - PX4 -Copter V3.4.2 - GPS 1 failing configuration checks

ArduCopter Copter 3.4

Hello,
I’m having some troubles tryng to use the ublox m8n GPS.
The error that i have is :“
GPS 1: u-blox navigation rate configuration 0x3FF
PreArm: GPS 1 failing configuration checks”

I’m using APM Copter V 3.4.2

The Gps that I’m using is not from 3dr, I’m using the default configuration. According to various forum that I’ve read I’ve set, using u-center, NAV5 Dynamic Model = Airborne >2g

Except from this error the Gps seems to be working fine. I get a 3d Fix with 16 sat, Hdop 1,33

Frame: QUAD
PX4: de6b667d NuttX: 8c965992
APM:Copter V3.4.2 (6076bdfc)

Thank you for any help.

The GPS isn’t responding to any attempt to send information to it and configure it appropriately. Check your wiring of the GPS module to make sure that the GPS’s Rx pin is connected appropriately to the Tx from the autopilot.

You actually don’t want to be filtering the model at 2G, you want to be using the 4G model, however the parameter for that GPS_NAVFILTER will override the value you saved to it.
