Hi Faisal, Thanks for the suggestion. I had tried briefly to install Dymo before but found I was missing some key wirings, among other problems. Do you know if there is an available code example that works (along with .h, config and implementation files)?
Also, right now all 20 motes can talk to each other within one hop. What is a good way to decrease the radio range for the mica2 - say no more than 1 or 2 meters? Is it the CC1000 control? Could you point me to a good help file on correctly implementing the controller?
