[Paparazzi-devel] No serial communication between PC & XBee?

[Alston Pike]

So, in the process of configuring my modems, I came to realize that the modem in the plane was bad and that it was part of my problems I've been having getting the GCS to populate.  I've got a new one now, and I'm able to work with that modem in X-CTU.

Now that I've got the plane reassembled with the new modem in place, I try launching a new flight.  The activity lights on the FTDI adapter never come on.  The power LED is on, and I checked dmesg and something is on ttyUSB0.  My GCS still will not populate.  

Here's everything I know:

Ground station modem:

XBee Pro Series 2. 
Configured with ZNet 2.5 Configurator AT function set (Firmware 1047)

PAN ID: 1337
Destination (DH) : 13A200
Destination (DL) : 402C135B
Serial (SH) : 13A200
Serial (SL) : 404BA6E6
Baud : 57600

Plane modem:

XBee Pro Series 2
Configured with ZNet 2.5 Router/End Device AT function set (Firmware 1247)
PAN ID : 1337
Destination (DH) : 13A200
Destination (DL) : 404BA6E6
Serial (SH) : 13A200
Serial (SL) : 402C135B
Baud : 57600

dmesg:

    ... the rest is as-is from when I downloaded the CVS.

I can send my airframe config file later if it would help.
