Question

my problem is that I send to external device byte array like this:
byte[] dataBuffer = new Byte[9] {1, 2, 3, 4, 5, 6, 7, 8, 9};
but when I read there these bytes, I get e.g. 2 when there should be 3. So it is always the left value.
Is it possible that there is something else at the beginning of array? Null value?

Answer 1

Bytes array is zero-indexed you might be considering dataBuffer[1] as first element but infact you have dataBuffer[0] first element.
