Can't use the RFXCom tranceiver

[Robke]

Hi All,

Iḿ trying to get the RFXCom tranceiver running in DomotiGa but i get the follwing error:

2012-04-28 22:27:22 RFXCom tranceiver support enabled.
2012-04-28 22:27:22 RFXCom transceiver Error: Cannot open serial port (#5) at CRFXComTRX.ConnectSerial.419
2012-04-28 22:27:22 ERROR: RFXCom tranceiver serial interface FAILED to connect to Port /dev/ttyUSB0
2012-04-28 22:27:22 RFXCom tranceiver Relay disabled.

The user domotiga = a member from the dialout group.
The device is mounted to the /dev/ttyUSB0 and i selected that device.. But still not working.

Iḿ using the latest (stable) version of ubuntu.

Can someone help me?

Thank you.

Had the same problem here, solved it by changing the ownership of the serial port.
sudo chown -R domotiga /dev/ttyUSB0

Grtz,

Can you unplug and plug your interface in the usb port and type dmesg?
What does it show as last lines?
I will test on 12.04 soon, but I have a prototype interface with different serial chip on it.
