CC2531: TIMAC : Delay time of the receive interrupt for the received signal

Sh.Sasaki

Part Number: CC2531
Other Parts Discussed in Thread: TIMAC

Hi experts,

My customer wants to build a system of time synchronization, with one transmitter master and multiple receiver slaves communicating.
They will using TIMAC(IEEE802.15.4 MAC Software Stack).

So I have two questions.

Q1)　Do you have information on the timing (delay time) of the receive interrupt for the received signal?
　　 This was not in the datasheet.

Q2) Do you have a sample program or related documentation for time synchronization using TIMAC?

Best regards,
Sasaki

If i right undesund you problem - you want to sinchronize same device. You can to try use algoritm of NTP protocol.. I try. It is work.

Hi Sasaki,

You can use beacon mode to synchronize the network and the RX/TX turnaround time is a maximum of 192 microseconds as determined in the datasheet. You will have to evaluate the TIMAC examples with a sniffer to further determine the delay times according to your application specifications.
