Hi, i have the code below to get the RSSI from mica2 motes. I will use it to
try and track one moving mote. I have 5 motes in total. The moving mote (a)
will have the code below, in order to communicate with all stationary motes.
The stationary motes will have to get the RSSI relative to the moving mote and
send their information to the base station with node id=0. How can i change the
code below to send the RSSI value to a specific node? What is the exact
replacement i need to do to the code for e.g. to send to node 0? Please
help!!!Many many thanks in advance!!!!!!Vas includes PongMsg;includes
