hi

I use Zstack 2.5.1a, you know,default Beacon Request Frame Dest Address and Dest PAN are 0xFFFF.

In my application, I want to change the value of Dest Address and Dest PAN to other value.

But I fond that when I change the Dest Address and Dest PAN value, the coordiantor Wireless Revice Interrupt Server Funtion can not work

I want to know why ?

    You can't change thing like that and expect ZC/ZR would response. The beacon request should use broadcast.

    I know that the beacon request should use broadcast,
    in my opinion, if a device sends a Beacon Request, ZC/ZR can receive that in low level layer, for example, the radio receive interrupt service routine will be servered when the Beacon Request was in the air,
    this is why TI Packet Sniffer Software can revice any wireless data based on Zigbee protocol
    so I want to modify the low level layer in ZC/ZR applications too,
    the problem is that why the ZC/ZR radio receive interrupt service routine can not be entered when the modified Beacon Request was sent?
