Re: AW: AW: [Paparazzi-devel] data upload to Twog v1 and modem communication

[Felix Ruess]

Hi Roman,

did you already connect your xbee modem and disconnect the usb cable
again (that is normally only used for flashing).
Which XBee versions do you use? Did you configure the XBee modems? If
you are using the Digi XBee Pro ZB (formerly named series 2) modules
you have to set them up according to
http://paparazzi.enac.fr/wiki/Modems#Setup
Try to only connect the XBee modem (you don't need to reflash so you
don't need the direct USB connection) and set the link parameters as
follows:
.../link -d /dev/ttyUSB0 -s 9600
since the default baud rate on the XBees is 9600 baud if I remember correctly.

Cheers, Felix

P.S.: you can also talk to other helpful people and me on the IRC
channel (if someone is active):
