[En-Nut-Discussion] Sending Numerical Data

[Thiago A. Corrêa]

Muhammad,

    Yeah, it appears that you are sending in ASCII. Althought I don't
understand your code. To use the binary value just dont enclose it with ' or
". Sorry I can't be of further assistance but I can't make much sense of
what the problem is.

Cheers.
