Hi
I use the ZStack 2.5.1a for CC2530.I found that the end device repeat transaction the data when it can receive the acknowledgement form its parent(actually its parent has repone it the acknowlwdgement). upon the phenomenon happened the end device will retransaction the data again and the sequence number of the packet retransation is same as previous. form my point of view,when the parent receive the retransaction data form its children will not be deliver to the appication layer,in other words,the SAPI_ReceiveDataIndication() can be called when the same transation sequence number has received. but actually the retransation data will be delivered again to the app layer. is the phenomenon correct?
