Re: [Paparazzi-devel] GPS not working

I have added what you suggested me, but there is no GPS in the Ground Control Station. The only lines in the airframe file I have related to GPS (Ublox LEA 6H) are:

 <modules>
    <load name="gps_ubx_ucenter.xml" >
    </load>
  </modules>

    <subsystem name="gps" type="ublox">
    </subsystem>

How long should the GCS take to detect any GPS signal? I have to connect the rx from the GPS to the tx in Yapa and tx from GPS to rx in Yapa, haven't I? By the way, I have Ucenter in Windows, not in Ubuntu, just if this could be the reason.

Hi,

If you have a ublox I would recommend to use 

<modules>
  <load name="gps_ucenter.xml" />
</modules>

This module has auto-baudrate, and configures all message rates and communication ports. (it does not change the filter mode, or functional GPS settings, only communication stuff: so it is always safe to use). 

The module will send a DEBUG message that indicates the firmware version in your GPS, the previously selected GPS baudrate and the current (38k4).

Hello,

Trying to get my RC working I have noticed that I cannot switch modes. Once I open the ground control station, it always stays as auto 2. I think this may be related to the fact that it doesn't identify any GPS signal and it works in a kind of failsafe mode automatically, can this be the reason? There is also an error in the Paparazzi Center saying "Unix.Unix_error(2, "read", "")". How can I get my GPS working? I have configured it with U-center and everything is ok, however, it never works when connected to Yapa.

Thanks,
