polling rate

Other Parts Discussed in Thread: CC2530, Z-STACK

Hello,

I am developing my code based on sensor demo app in CC2530. I have a question about polling rate. I understand that POLL_RATE defines the number of milliseconds to do sth but I cannot understand what exactly happens when an ED send data request polls to it's parent? and what happens if I turn this option off?

I appreciate any help.

    Hi Leila,

     

    Have you read the "Power Management For The CC2530.pdf" document - section 6,

    you can find it in your Z-Stack installation folder/documents/cc2530.

    If you turn the poll rates (as you will see, there are several types of polls) off, the ED

    won't be able to receive data (App data, ACKs etc..) which will finally lead to errors

    in communication. You can do a quick experiment with ZED, ZC and a packet sniffer

    and see what happens when you turn off one of the polls (or all the polls).
