General Questions

I Think I Found a Bug, Where Can I Post It?

In the issue tracker. Please make sure to check the existing issues so that issues are not posted twice.

Is There a Mailing List?

Yes, there is! Please see Mailing List for details.

How Can I Contribute?

Easily! The only thing you need is a github account and you're ready to go. If you want to contribute documentation please simply edit the Wiki. Please check Contributing for more information if you want to contribute code.

How Can I Use Serial Port Autodetection?

Please see Serial Port Autodetection.

How Can I Customize the Logging Behavior?

Please see Logging Customization.

Is it possible to use embedded systems like Alix as gateway hosts in my testbed infrastructure?

Sure it is! We tested the deployment of a small-scale testbed with 1 testbed server and 1 Alix acting as a gateway, with a few telosb nodes connected to it. We used the linux voyage distribution on our Alix, so if you use that one you should not have any problem. For details on installation and configuration, just follow the instructions, there is no difference in using an embedded system or a standard pc!

When running TR from my IDE the connection to the Session Management Service hangs

This behavior has been observed at least on Mac computers depending on the current connectivity status (WLAN, Ethernet, ...). Sometimes the TCP connection to the service is made but then no data is transmitted between Web service client and server and eventually the connection times out. This can be fixed by not binding to all network interfaces (i.e. not using 0.0.0.0 as binding IP address). Please pass the command line parameter -DdisableBindAllInterfacesUrl to the JVM when starting TR to disable binding to all interfaces.

Can I specify a default image that is automatically flashed to the nodes after a reservation is over?

Yes, you can (since 0.8.4)! Everything you have to do in order to do so is to specify the path to the default image file in '''conf/tr.iwsn-testbed.xml''' as in the following example:

<application name="WSNDeviceApp" factoryclass="de.uniluebeck.itm.tr.runtime.wsnapp.WSNDeviceAppFactory">
  <wsn:wsnDevice xmlns:wsn="http://itm.uniluebeck.de/tr/runtime/wsnapp/xml">
    <urn>urn:local:0x1234</urn>
    <type>isense39</type>
    <defaultImage>/full/path/to/the/defaultimage.bin</defaultImage>
  </wsn:wsnDevice>
</application>
