• Switch off all the motes, except the one connected to your computer.

• You can set its join duty cycle (between 0 and 255) by entering the following command:

  > mset joindc <duty_cycle>

• You can read the join duty cycle by entering the following command:

  > mget joindc

Fill in the table below. For each measurement:

• change the join duty cycle on the mote

• switch the mote off

• power-cycle the manager

• switch the mote on and start a stopwatch

• stop the stopwatch when both LEDs are on
  

  joindc=55 joindc=155 joindc=255 try 1 try 2 try 3 average

  
  

• Plot the average join time as a function of the join duty cycle:
