[Paparazzi-devel] no uplink with xbee pro version 2

[Loïc Raffard]

Hi,

We are a group of student from the Isae/Supaero in Toulouse and we are 
trying to fly a Twog equipped aircraft.

Our problem is that in using xBee Pro 2.4 gHz version 2 we only have a 
downlink but no uplink. Has anybody encountered something like that 
before? Our  modems are configured using X-CTU and are set on 9600 
bauds. For the ground modem we tried Xnet 2.5 coordinator AT and for the 
aircraft modem end device/ router AT  with the same Pan ID and different 
node name, we also tried Zigbee coordinator At for the ground modem and 
End device At or Router AT but we always had a downlink but no uplink.

We also tried to put our old Radiotronix modem and this time it worked 
both uplink and downlink using the same .xml for paparazzi center.

In X-Ctu the modem with the coordinator is working when we use the Range 
Test but not the one in the aircraft.I don't know if it's normal.

Thank you very much
