Thank you for the reply. Im pretty sure how to get data:) btw, Im using Iris mote (chip is RF230).
What Im trying to do is to measure the time to send and receive a packet, and I want to measure these time even if a node is unable to communicate with other nodes. Is this the problem of hardware? or OS? IF this is the restriction of TinyOS, can I modify it to solve this problem? Thank you.
