Hi, If the delays are due to backoffs then disabling the CCA should give me lesser delay rite??
But its still the same.. Printing local times at CC2420 Transmit and Receive programs what i found out is that at the sender there is a min delay of 9ms between call AMSend.send command and the SendDone event. Also at the receiver side there is a delay of 13ms by the time receive event is triggered in the application when compared with the timestamp.. Can these delays be trusted or is there any mistake in this analysis?? > >> On Wed, Mar 31, 2010 at 1:40 AM, Deeksha Rao Sahib >> <[email protected]> wrote: >>> >>> Hi all, >>> >>> I am using FTSP in my code for time sync and I've been trying to >>> measure >>> the hop delay for different links in the network.
