Hi,
Well, using halSleepWait(...) is not a good thing, for a couple of reasons.
First reason to not use the halSleepWait() - it is not the highest API function for an application user
(though the Z-stack code is partially visible and open for an user, you shouldn't be messing with
lower layers of Stack). The second reason - starting from Z-stack Ver.2.4.0 (I think)
this function was moved (or removed) and it's not longer available for application use, therefore the
linkage error.
Back then I thought of halSleepWait() as a perfect solution for "power conserving non blocking delays".
Now I know it's not true and obviously I was wrong suggesting to use this function - shame on me.
You should be using OSAL API for this kind of things, for example to wait 50mSec
you can use osal timer - osal_timer_startEx(my_appID, SOME_EVENT, 50) to schedule
some event to be invoked in 50mSecs.
