====== Running the Delta Application ======
Start your application in a terminal while the above command is still running	 
<code>
ost@bblue:$ sudo ./bin/delta -c bin/HwConfigBBBlue.json
</code>


===== Autostart =====

Usually you want run the application upon startup of the board after you applied power.
For this purpose you have to copy two files from the //bbblue-scripts// folder of [[https://github.com/eeduro/eeduro-scripts|]] to your target:
<code>
$ scp ./bbblue-scripts/start.sh ost@192.168.7.2:bin
$ scp ./bbblue-scripts/delta-startup.service ost@192.168.7.2:bin
</code>
Make sure that ''start.sh'' is executable on the target. ssh into the target and run:
<code>
ost@bblue:$ chmod +x bin/start.sh 
</code>
Further, copy the file ''delta-startup.service'' to the right location, so that your systemd can find it upon initialization.
<code>
ost@bblue:$ sudo mv bin/delta-startup.service /etc/systemd/system/
</code>
As a final step you have to enable the service with
<code>
ost@bblue:$ sudo systemctl enable delta-startup
</code>
and reboot with
<code>
ost@bblue:$ sudo /sbin/reboot
</code>
Now, the Delta application will start 5s after the board is powered up and the operating system finished its bootup procedure.

===== Get Output of Loggers after Autostart =====
The Delta application periodically logs various state information. To see this output the application was started in a detached screen. To see the log output from the application just reattach to this screen session. First connect to your target with 
<code>$ ssh ost@192.168.7.2</code>
then reattach with
<code>
ost@bblue:$ sudo screen -r delta
</code>
You could also terminate the application by pressing ''CTRL-C''. \\
