Serial issues following upgrade to OH2

Add-ons Bindings
1

I’m trying to finish my upgrade from OH 1.8 to OH2. I did a complete rebuilt from the group up, so there is nothing comflicting with the old version of OH. I think I have everything working except for communications using the serial binding. I am communication using an arduino attached to a raspberry Pi 3 via the GIPO serial. I am getting good data in through minicom, but it doesn’t seem to be getting into OH2. In my items file I have

String Serial “Serial [%s]” (g_Diagnosis) {serial="/dev/ttyAMA0@19200"}

which does not update as data comes over the serial line. This was working well in OH 1.8.3. I installed the 1.9 serial binding via the paper UI. At this point I don’t even know where to begin troubleshooting.

One thing to check is to make sure that the user openhab is a member of the dialout group: sudo usermod -a -G dialout openhab

Also, put the serial binding in DEBUG to check the logs

log:set DEBUG org.openhab.binding.serial

in the console ssh openhab@localhost -p 8101 with password: habopen

I had already added openhab (and pi, not sure which it cares about) to the dialout group. As I understand though, that only prevents writing to the serial bus, not reading from it.

log:set DEBUG org.openhab.binding.serial

When input at the SSH console returns

-bash: log:set: command not found

Or am I misunderstanding that.

Looks solved. I followed this advice in this thread:

https://community.openhab.org/t/openhab2-razberry-z-wave-binding/13033/11

Specifically this part:

For those using the Razberry board, it seems that this line -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0" needs to be added to /usr/share/openhab2/runtime/karaf/bin/setenv under

export JAVA_OPTS="${JAVA_OPTS}

at the end and the ending quote needs to be removed after -Dorg.osgi.service.http.port.secure=${HTTPS_PORT}".

export JAVA_OPTS="${JAVA_OPTS}
-Dopenhab.home=${OPENHAB_HOME}
-Dopenhab.conf=${OPENHAB_CONF}
-Dopenhab.runtime=${OPENHAB_RUNTIME}
-Dopenhab.userdata=${OPENHAB_USERDATA}
-Dorg.osgi.service.http.port=${HTTP_PORT}
-Dorg.osgi.service.http.port.secure=${HTTPS_PORT}
-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0"
