Xbee Network API Frame

Question

I have a question: I send 2 Data Byte: E3/A5 : E3 first, A5 at least.
But i become on the XCTU-Terminal/ A7 / 63
The coordinator is in API-Mode.
here is the all API frame:
7E 00 0E 90 00 13 A2 00 40 AD 81 7C 7D 06 01 A7 63 42 !!!
Why A7 and 63 and not E3 and A5??
I hope somebody can help me!!
I'm despair....

Answer 1

You should be using the newest XCTU, version 6.1.2.

Go to the API console and use the Frame Generator tool to create your frame. I have tested this here with the 23A7 firmware and the frame I get is a receive packet:

7E 00 0E 90 00 13 A2 00 40 AD 81 7C 7D 06 01 E3 A5 C4

Answer 2

That is because your words E3 and A5 are written on hexadecimal code that in this case are A7 and 63.

Hello,

Sorry for being late, but the reason you can't see E3 as E3 and A5 as A5 is because you have to imagine this with machine language. For machine every character is a group of bits (10101010) and that group of bits you can represent it in different ways and one of them is hexadecimal. Instead of machine write 1011100101110010 (for example) for E3 and 11101010101010 (example too) for A5, they write it on hexadecimal as A7 and 63.
