first 2 bytes of MSB of serial missing on incoming packet

I see “13a200” but I would like 0013a200. any body know where these went?

Which packet are you receiving?

In all the packets you will receive full xbee address i.e., 0013a200.

Refer the ZigBee product manual at the following link, http://ftp1.digi.com/support/documentation/90000976_K.pdf for more details

Do note that the incoming data is 8-byte binary, so if you (or your programming language) convert this to integer, some programming languages will not show leading zeros.

This is really a good things to post this type of information which is very rare to find and get the detail information.
