When I send an API ND command from a VB program using the following packet;

7E 00 05 08 01 4E 44 00 64

I get;

7E053F14E4413F

Its a response – but not as I know it. Neither the checksum “3F” or command length “05” are comprehensible to me. Any suggestions for decoding? Both coordinator and endpoint are XBEE PRO S2Bs.

That is not a valid response from the radio. Try using XCTU’s Terminal tab and the Show Hex function to verify the frame you are sending and the response back that you should expect.
