Build the Agent
To build the program, click the hammer icon at the bottom left of the screen. This will take a while on the first build since QtCreator needs to build the COSMOS Core source, but subsequent builds will be faster. If your program is bug-free, you'll see a green bar at the bottom right of QtCreator when the build is complete.
Note: if only you want to run the agent locally, you can just click on the green triangle, and skip the next section.
Deploy the Agent on the BeagleBone
Note: you can skip this step if you only want to test your agent locally.
Tip: if you haven't used the Cloud9 IDE with the BeagleBone before, you should check out the Getting Started tutorial series
Next, you'll need to deploy your agent to the BeagleBone, meaning that you will be moving the agent executables from your local computer onto the BeagleBone.
Copy the Executable
You can copy the build folder to the BeagleBone by running the following terminal command:
rsync -auv ~/cosmos/source/projects/my_project/build-beaglebone debian@beaglebone.local:/home/debian
Enter the password (default is temppwd), and wait a minute while the files copy over. From Cloud9 on the BeagleBone you should see the build folder appear in the home directory (/home/debian):
Run the Agent
To run the agent, you can enter the following command in a Cloud9 terminal:
~/build-beaglebone/my_agent
Note: if you get an error when trying to run the program, run the following command to give the file "execute" permission and enter the password (default is
temppwd):sudo chmod +x ~/build-beaglebone/my_agent
You should now see the output from your agent!
Try Calling a Request
Now that the agent is up and running, you can try calling the say_hi request we added in the previous section.
To call an agent request from a terminal, we use the following syntax:
$ agent <node name> <agent name> <request name> [request arguments...]
In this case the node name is cubesat by default, the agent name is my_agent, the request name is say_hi, and
we don't need to supply it with any arguments.
Open up another terminal and try it out:
$ agent cubesat my_agent say_hi
Note: the screenshot above is for running agents on the BeagleBone. If you're testing locally, then you will be using Ubuntu's terminal.
Stop the Agent
Once you're done testing out your agents, you should terminate them by pressing CTRL + C in their terminal window.
