3. Tiny Application Sensor Kit TASK Field Tool User Manual David Gay Intel Research dgay intel research net March 19 2003 1 Introduction The field tool is a simple tool for debugging TASK based sensor networks in the field The field tool allows a user to walk up to a TASK mote and inspect or modify its state by issuing a set of simple commands The field tool only operates on the motes that are in direct radio range 1 e close proximity to the user The field tool runs on handhelds devices currently HP Ipaq s running Linux equipped with a Canby or Canby2 compact flash mote 2 Mode of Operation Before the first use the field tool should be configured as explained in Section 4 Once started the field tool presents the user with the screen shown in Figure 1 The top left pane is a list of commands command pane that can be sent to the mote the top right pane is a list of the motes mote pane that the field tool has discovered in the local neighbourhood the bottom pane result pane displays the results returned of field tool commands as returned by the motes TASK motes spend most of their time asleep they will not discover and be discovered by the field tool until the next time they wake up Once a mote notices the field tool it will turn on its yellow LED and switch to an always on state Simultaneously assuming no radio problems the field tool will update the list of motes known to be in

5. nnectivity may lead the mote to execute the command but prevent the mote s answer from being displayed by the field tool It is possible to scroll through the answers from previous commands using the left and right arrows at the top right of the result pane The title area of the result pane shows the destination of the command ALL or a mote number the command name and the time the command was executed The results from the latest command are displayed in red without a time 3 Field Tool Commands There are currently four commands defined in the field tool e green toggle the green LED This can be used to check that field tool mote communication is working Motes just return done as the result e beep sound the mote s sounder this obviously requires the standard mica sensor board The purpose is similar to green Motes just return done as the result e reset Reset the mote Note this command has no result as the mote just reset itself e ping Return vital statistics on the operation of the TASK mote The result is of the form X V Parent N RAM R qin Q mhq M dpth D qual L q1 Q1 q2 Q2 where X is the current voltage of the mote s batteries Nis the parent of this mote in the routing tree R is the amount of RAM available for queries on this mote mica2dot motes do not have green LEDs so you won t see anything but you will still get the done result Serial
