RFXCOM not starting on RPi

[Robert van Bregt]

I have migrated from Mac Mini to RPi. 

I can see the rfxcom device at /dev/ttyUSB0 using RFXcmd (http://rfxcmd.eu) but when I start openHAB (debug mode for RFX binding) I get this error message:

2015-04-01 22:47:30.604 [ERROR] [.b.r.internal.RFXComConnection] - Connection to RFXCOM controller failed.

Running 1.6.2

Any suggestions are appreciated.

Make sure you have rfxcom:serialPort = /dev/ttyUSB0 in openhab.cfg

Otherwise, it may be a permissions issue.  Try setting up a udev rule as shown in step 3 under x86 Linux at https://github.com/openhab/openhab/wiki/Hardware-FAQ

[Robert van Bregt]

The openhab/cfg is correct. I also expected a permissions issue.



I have created a rules file, but cannot seem to get a /dev/USBrfxcom device listed

This is the contents of my /etc/udev/rules.d/50-usb-serial.rules file

$ cat /etc/udev/rules.d/50-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{product}=="RFXrec433", SYMLINK+="USBrfxcom", GROUP="dialout", MODE="0666"

I have used

$ udevadm trigger

No /dev/USB* files visible

$ ls -l /dev/USB*
ls: kan geen toegang krijgen tot /dev/USB*: Bestand of map bestaat niet

I have now changed permissions to the /dev/ttyUSB0 device

$ sudo chmod 666 /dev/ttyUSB0
$ ls -l /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 0 jan  1  1970 /dev/ttyUSB0

After restart of openhab with

$ sudo /etc/init.d/openhab stop
$ sudo /etc/init.d/openhab start

I get this error in openhab.log

2015-04-02 05:26:44.060 [INFO ] [.b.r.internal.RFXComConnection] - Connecting to RFXCOM [serialPort='/dev/ttyUSB0' ].

I think I need some help / advice in creating and activating the udev device.

After investigating

$ sudo udevadm info --attribute-walk --path=/sys/bus/usb-serial/devices/ttyUSB0

I modified the rules file to

$ cat /etc/udev/rules.d/50-usb-serial.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{product}=="RFXtrx433", SYMLINK+="USBrfxcom", GROUP="dialout", MODE="0666"

When I unplugged and re-plugged the device, I could finally see it:

$ ls -l /dev/USB*
lrwxrwxrwx 1 root root 7 apr  2 06:26 /dev/USBrfxcom -> ttyUSB0

After a restart of openHAB, the binding did not show any errors any more and started doing it's work. It was a permissions issue after all...

Unfortunately I had to re-install OH (different topic).
I rebooted the RPi including OH.

The error re-appeared:

2015-04-09 23:27:22.204 [ERROR] [.b.r.internal.RFXComConnection] - Connection to RFXCOM controller failed.

These are my devices

$ ls -l /dev/*USB*
crw-rw-rwT 1 root dialout 188, 0 apr  9 23:28 /dev/ttyUSB0
lrwxrwxrwx 1 root root         7 apr  9 23:26 /dev/USBrfxcom -> ttyUSB0

This is the udev rule

$ cat /etc/udev/rules.d/50-usb-serial.rules
# /etc/udev/rules.d/50-local-usb-serial.rules
# After making a change 'sudo udevadm trigger' will update symlinks.

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{product}=="RFXtrx433", SYMLINK+="USBrfxcom", GROUP="dialout", MODE="0666"

What permissions should I have where?

Did some additional searching in this forum and found the solution.

$ sudo nano /etc/init.d/openhab

Then add

-Dgnu.io.rxtx.SerialPorts=/dev/USBrfxcom
