[Paparazzi-devel] strange modem problem

[Chris]

I have a strange problem with radio modem communication.
I finally made the joystick work perfectly well but only when i use the 
xbee 2.4 ghz modems at 9600bps.
Everything works fine when i use the Xbee pro modems at 9600 bps but 
when i try to use the 9xtend modems the joystick movements become 
erratic and the downlink data rate also becomes very slow  to the point 
of losing communication every 3-5 seconds according to the Link 
indicator of the GCS. The GCS takes a lot of time to populate (more than 
a minute!) when started.
Without the joystick the data rate is excellent and data upload to the 
aircraft is also very fast....
Has anyone seen this behavior before?
