[Paparazzi-devel] Radio module: Lairdtech LT2581 vs XBee Pro (pin compatible)

[Meier Lorenz]

Hi all,

I was wondering if anyone has used the Lairdtech LT2581 outdoors. I've used 
them indoors extensively, also in Wifi and XBee cluttered environment.

Turns out the Lairdtech modules still get something to the target when XBee and 
Wifi drop dramatically large packet numbers.

I did the control link for some autonomous quads with them (only the link, the 
credit for the control design is with the group of Prof. d'Andrea):

I'm asking all of this because the Lairdtech modules are pin-compatible and a 
drop-in replacement for XBee and we're considering them as outdoor modules 
instead of using XBee (currently our main module for telemetry, whereas 
Lairdtech is used for control signals):
