Confused by the command-line options!!!!!
i find some problems in the file f8Wconfig.cfg, like:
/* The number of items in the broadcast table */-DMAX_BCAST=9
what's the meaning of MAX_BCAST？
what's more，there are so many POLL_RATE， like
/**************************************** * The following are for End Devices only ***************************************/-DRFD_RCVC_ALWAYS_ON=FALSE/* The number of milliseconds to wait between data request polls to the coordinator. */-DPOLL_RATE=1000/* This is used after receiving a data indication to poll immediately * for queued messages...in milliseconds. */-DQUEUED_POLL_RATE=100/* This is used after receiving a data confirmation to poll immediately * for response messages...in milliseconds */-DRESPONSE_POLL_RATE=100/* This is used as an alternate response poll rate only for rejoin request. * This rate is determined by the response time of the parent that the device * is trying to join. */-DREJOIN_POLL_RATE=440
although there are some comment，but i find it is difficult to understand these parameters，could you give me some help and show me some details，i am confused by these parameters.
Man oh man - 5 consecutive exclamation points - I think that there is an E2E maximum of 3 ;)
The enormous configurability of the Z-Stack can be daunting at first, but it all starts to gel soon as you become more familiar with it and with the ZigBee specified behavior it implements - have you seen the ZigBee spec lately (I could add some exclamation points to my expression of exasperation with how complex that has become ;)
Anyway - these detailed POLL rates don't even need to be changed until you are very familiar with working with the stack and and very far along in development of your proprietary application and are ready to start drilling down into finely tuning the power optimization of an ZED (ZigBee End Device or RFD - reduced functionality device).
To be sure, you can read more about them here:
C:\Texas Instruments\ZStack-CC2530-2.5.0\Documents\Z-Stack APIC:\Texas Instruments\ZStack-CC2530-2.5.0\Documents\Application-Level Tuning of Z-Stack.pdf
Also, there is a LOT of discussion here on this E2E about power savings in a ZED and the strategies and gotchas to chaning the aforementioned poll rates ... just search for it on topics like 'poll rate', 'end device', 'power saving', 'sleep', etc.
