Hi,

I have 4 Xbees S2B, 1 coordinator and 3 Routers. From coordinator i am sending
7e 00 1b 10 01 00 00 00 00 00 00 ff ff ff fe 00 00 48 65 6c 6c 6f 20 57 6f 72 6c 64 21 21 95

and on the receiver side i am getting

7e 00 19 90 00 13 a2 00 40 bd ec 72 00 00 02 48 65 6c 6c 6f 20 57 6f 72 6c 64 21 21 ff

The message sent is ok but i notice a 2 byte difference in message length and i do not know the bytes that are discarded and the reason.

Can any one help me to solve this?

Both frames looks perfect to me.

You will not see exact same frame on both Tx and Rx side. On Tx side, you will provide 0x10 Tx Req frame. While on Rx side, module will report 0x90 Receive Packet packet. That’s the reason for change in packet length.
