[weewx-user] Re: Selection of USB/RS232 device to RPI. To control WMR 928

2017-03-01 Thread Per Edström
I have WMR928 with a RS232-to-USB and it works fine. Have been running for 
many years.
I run Ubuntu 10.04.
Sometimes the /dev/ttyUSB0 changes to /dev/ttyUSB1 so Weewx lost contact 
but I solved that by adding a device-link that points to the current 
USB-device..

Well, I don't have RPi3 but an eBox 3350 but I don't see why it shouldn't 
work on RPi3..

An rs232 -> usb which uses an FTDI chip works the best as it usually contains a 
serial number which is useful in setting up a udev rule. Mwall has posted a 
good guide to creating a rule for this purpose. I had been using a converter 
with pl2303 chip but started having problems with it switching ttyUSB on me.

I think my converter have PL2303-chip and it changes USB-device sometimes. 
But my soft-link fixes this problem now..
