I have also upgraded my WeatherDuino Tx and Rx units to use the latest v2.0 software, but I still cannot get it to connect.

Any help with this would be much appreciated.

Please check / try this:

- Check if after having programed your RX unit, you have put the VP1 switch at close position, otherwise the unit always reboot as soon as you try to start Cumulus (1 or MX)

- Check if your RX unit is powered by the external power supply (A powered USB hub is not required)

- In the PI terminal window:
Do a "ls /dev/tty*", with the RX unit unplugged. Then plug the RX unit in and repeat the ls command. The difference in the two lists should be your device. Usually shows up as ttyUSB0

- Edit Cumulus.ini file and check the com port name in use. Usually it is: ComportName=/dev/ttyUSB0

- Revise all [Station] section in Cumulus.ini, and check if the above statement is not duplicate somewhere.
