[Paparazzi-devel] Booz datalink

Hello all...

So its been about 10 days Im trying to figure out why we cant get the datalink up, and I finally gave up and decided to switch to maybe working with the test programs first. We are working on a quadrotor using a copy of booz_a1 airframe. I am hoping someone can step in here and help out because Im drowning in code and trying to make sense out of this. Anyways, the main question here is regarding booz_test_downlink and booz_test_modem. Im guessing the latter is supposed to be used to test the modem and the former for more messaging using the datalink. booz_test_downlink currently compiles but booz_test_modem doesnt. Uploading test_downlink however generates absolutely no activity on the modem (tx led should be blinking everytime it sends the cputime).

When I checked booz_test_modem I noticed the DOWNLINK_SEND_TIME command didnt have the channel defined, so I set that to DefaultChannel. The next error is that uart1init() is undefined. I checked as far as i can see theres only a uart.h header defining the prototype for the function but no implementation file uart.c in airborne/booz. Is the file missing or is it supposed to look for uart.c elsewhere?

Also, if anyone can tell me a clear method for configuring the modem for the autopilot on booz Id be much obliged. The method defined on the website ("") creates a compile error when using the booz airframe.
