You may be having GPS reception problems. If GCS is showing some GPS
signal, communication between the Tiny and the LEA is working. If you've
already uploaded the correct paparazzi settings to the GPS, it's possible
that there is an antennae problem or that you are in a poor signal
strength area - indoors, around tall buildings or where there are strong
WiFi signals are all possible places where there will be poor GPS.
You don't need any drivers for linux - all the drivers (also called
modules in linux-land) which you require to run paparazzi are included
within the operating system.
Did you remove the brltty package as per the instructions on the wiki?
Failing that, it's probably a mismatch in baud rates somewhere along the
line. When getting started, make sure that ALL baud rates for the
downlink match - the one in the airframe file, the one configured in your
WI232's and the one selected on the groundstation.
Hope this helps.

Thanks for your help!
We are working with tiny 2 and mainly have two problems now.
1. Our GPS is U-Blox LEA-5H. We have successfully configured it with
U-Center software, but there were no signals in U-Center, only some blue
bars and may disappear soon. In paparazzi center, we can connect our
and show the flight configuration in GCS, but there were also no signals
GPS tab -- still there were some red bars and may disappear soon. the
shown in there is around 20.
2. The above procedures are all by wired connection. When we try to
to wireless connection by APC220 (or WI232EUR) wireless module, the
connection is not established, and there are no signals (all black) in
We have checked the wireless connection in windows, and it seems fine by
some test software. I think may be we need some drivers in LINUX?
Do you guys have similar problems?
