Check that you receive messages in the message console. See Tools | Messages. When you get data there, the link is working.
The most important thing to appear there are the aircraft / flight plan lines and symbols. If you don't see those, something is amiss.
the background tiles only appear after you click the globe symbol in the same window, top right. Not sure if a position fix is required
prior to tiles loading however.

I had one issue on ubuntu on my netbook that the gcs remained totally empty. I resolved this by using the xfce window manager in ubuntu,
rather than unity.

Hello everyone,

Has anyone tried to connect the Yapa2 directly to the computer (without the use of Xbees) using the serial port of the computer? We are trying to connect the Yapa2 to the computer through the serial port that is marked on the attached picture. 

On the other hand, I think we have configured the "transparent serial" protocol. Basically all we did is the following on the airframe file:

  <firmware name="fixedwing">
    <subsystem name="telemetry"     type="transparent">
      <configure name="MODEM_BAUD"  value="B57600"/>
      <configure name="MODEM_PORT"  value="UART1"/>

We are not sure if we have configured the "transparent serial" protocol correctly. The problem we are having is that the ground stays black. However, we don't get any errors from the Data Link on the Paparazzi Center.
