Introduction

This exercise is to familiarize the user with the collect view app provided in the Contiki OS source code. It basically involves a sink mote and one or more than one source motes. The source motes send their sensor, network, power and node properties to the sink. A java app presents all this compiled data in a graphical manner.

You Will Learn

• How to upload an introductory code for UDP source and sink.
• Things to see on the collect view gui.

Relevant Directories

• /contiki/examples/collect/ - This has the shell code for collect view and the various targets.
• /contiki/examples/ipv6/rpl-collect/ - This has the codes which are to be uploaded to the source and sink motes for UDP communication.
• /contiki/tools/collect-view/ - This contains the java file for the collect view GUI.
• /contiki/apps/collect-view/ - This contains the codes corresponding to the targets mentioned in the examples folder.

Connect the Tmote Sky

Before continuing with the tutorial, plug 2 Tmote Sky into the computer's USB port, one for the source and the other for the sink.

In order to transfer the ownership of the contiki directories use the following command.

sudo chown :user /dev/ttyUSB0
