I have three nodes Coordinator (C), Router 1 (R1) and Router 2 (R2). At the beginning, I communicated all of them putting near by each other successfully, later I create a "daisy chain" topology, which R2 connect to the PAN by R1 and R1 to C, and putting the communication many-to-one route, assigning AR = 3C (updating routing table each 6minutes) and it worked perfect. I receive in the both nodes Frame 0xA3 and my R2 send transmit request 0x10 and receive the ACK and when I disconnected R1 my router receive Network ACK Failure 0x21 in the ACK (it is ok because there is not path to communicate R2 to C). However, when I power up R1 again, the message is still same. It is like the R2 didn't connect again with R1, though it is still receiving the Many-to-one frame 0xA3 from the coordinator (this is only once R1 is powered up again).
Anyone can help me
