Chandru has already pointed out that you can't pass a tuple as the
second argument to gen_tcp:send/2. You're generating the tuple here:

Looking through the module, it looks like it would be a bit clearer if
you used the binary syntax, e.g. instead of writing

 > accDecode([255, Length1, Length2, 1 | DataList]) ->
 > 	Length = (Length1 * 256) + Length2,

you could write

  accDecode(<<255, Length:16, 1, Data/binary>>)

N.b: the above is _not_ a list. See:
