[Paparazzi-devel] XBee suddenly does not work

Hello everybody,

after having properly installed airspeed-sensor and xbee-modems to the Tiny 
(2.11) I started installing the ArduIMU to the airframe file. The build is 
successful in the mean time but after transferring to the Tiny 2.11 XBee 
communication does not work any more.

The error message is like:
Failure("Error opening modem serial device : fd < 0 (/dev/paparazzi/xbee)")

The modem works with XCTU fine. All preferences are fine like PAN and baud 
rate). I guess it is some error between PC (Ubuntu) and XBee-modem, maybe with 
the USB port. I checked it with udevadm monitor --property  but it seems fine 
to me (see attached message of udevadm monitor)

Any idea?

By the way: in the airframefile I put ArduImu to i2C0 and airspeed-sensor to 
i2C1. Is that necessary?

Best wishes,
