hello

when the latest firmware is loaded in my arduimu v2 flat the blue gps led never goes on .

after the initial startup sequence ( ok with 3 leds flashing ) only the yellow led is on .

when the arduimu utilities software is launched i can't see any bargraph moving (accel, gyros) and the cube don't move

my gps is an EM406 , my cable to load the firmware is an FTDI BASIC .

Thanks Philippe

anyone has tested em406 with arduimu ?

I have it working directly with the ardupilot, but it does now work wirh the arduimu. I am new to the project an it is difficult for me to debug this.

You need to set the software for your GPS module--by default it's set up for the uBlox. Change this to 2, as shown:

// Ublox gps is recommended!
#define GPS_PROTOCOL 2 // 1 - Ublox, 2 - EM406, 3 - NMEA

When you get GPS lock (which can take up to 15 minutes the first time), the blue LED will come on.
