| I think I've been having similar problems combined with power supply issues... :-( First I fried one XBee unit by plugging it into the FTDI cable which I though was 3.3 volt because of the details of the item when connected to USB port. (came up as ...FTDI... 3.3v) Next I've made a power supply from the 5 volts using an LM317 power regulator but I think under load the power supply is unstable so will try again with a low drop out regulator. I think this has resulted in partial flashing of another XBee that I bought as a replacement. I hope there's a power up sequence that can be used to re-flash it. Must read the docs more thoroughly first... I'd love a copy of your config docs is you wouldn't mind. Thanks, Bernie.

The biggest thing, however, is getting all the settings right and flashed to the modems via X-CTU. If you need anything, I've got a fairly detailed paper that I wrote to detail the installation and (some of) the configuration of the autopilot system which I can post online.

Are you able to remember any details of what caused the problem and the solution or what I've missed and post them here? Thanks, Bernie.

I have the Flight USB setting for transparent operation using the PPRZ protocol. Interesting note... when I use the Flight - Maxstream @ 57600 option, I get some activity on the transmit & receive lights on the adapter board but when I use the transparent options, I get nothing.

I hope this will hleps. good luck Chen 引述 Alston Pike <address@hidden <mailto: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.
