Dear Friends: Here, I am wondering on your 802.15.4 module. That is when I want to assign a tree address to the joining device, we will get into the "void SSCS802_15_4::MLME_ASSOCIATE_indication" function, here I want to to assign the address by calling the zbr agent function . I am wondering how you can call the zbr agent function and variables ?that is how we should do "zbr = getZBRLink(mac->index_);" to get the local routing agent pointer in sscs.cc file? your reply will be really appreciated, thanks alot in advance! yours, Delai Lu _________________________________________________________________ MSN圣诞礼物火热登场,免费发放中,快来领取吧! http://im.live.cn/emoticons/?ID=18
