Hi there

Have you try to use FTDI cable instead of mdoem to check if the GCS has some reaction?

2nd thing, you use the Xbee or PPRZ for the modem? because if you use PPRZ (which should work with you Xbee, but just no multiple aircraft operation), then you need to use option"flight by usb 9600", and in this option, you need to change the rate to 57600 (same as your modem).

  I hope this will hleps.


good luck
                                                                       Chen


引述 Alston Pike <address@hidden>:

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.

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)

Serial (SH) : 13A200

dmesg:

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

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