Hi all,
I tried to record the transmitted SFD time and received SFD time in the data
payload by the interface RadioTimeStamping.
Two micaz motes are used, one sender and one receiver. The sender sends
packets periodically. Whenever the receiver gets a packet, it sends the
corresponding ack recording the original packet's transmitted SFD time
immediately. And the received SFD time is recorded when the sender receives
the ack.
Assume that the two motes are stationary, and the RTT approximately equals
to received SFD time minus transmitted SFD time. But when I changed the
period of the timer of the sender , the RTT changed a lot. How could that
happen? Can anyone help me? Thanks a lot.
