Unable to connect to Davis Vantage Pro2 with Raspberry Pi 2

[peter94506]

Just got a Raspberry Pi 2 running Raspbian Wheezy
mono version 4.0.2
I can start CumulusMX and access via the web browser and edit setting. I've done the restart, and tried rebooting but can't connect to the console. When I start Cumulus is says it's unable to connect to the station.
The problem seems to be with the connection of the console to the USB of the Raspberry Pi 2

It's getting the "can't open device", I'm not sure why it's unable to see the Davis console.

Any help would be appreciated.

What COM port does dmesg say the cp210x converter is attached to, and what do you have for "Serial port name" in the Cumulus station settings?

[peter94506]

not 100% sure how to read the output from dmesg, but looks like 0, and I have com0 set in CumulusMX. Strange thing, even though I have set the station type/model to the Davis Vantage Pro2/Vue, when I look into the ini file , it's blank

[steve]

It's on ttyUSB0, so you need to put /dev/ttyUSB0 for the serial port name in Cumulus. This is documented here - https://cumulus.hosiene.co.uk/viewtopic.php?f=27&t=12943

[peter94506]

Thanks for the quick reply. That worked! I just missed that bit of information in the FAQ ;-(

Check your Paypal account. I'll periodically continue to donate as long as I use CumulusMX. Very nice software.

[steve]

OK - many thanks.
