Hey, unknown human being, thanks for the patience. I appreciate it.
maybe there's a misunderstanding about sending the data as an ascii c-string. is there?
Yes. I think I dont understand how serial comunnication works
If I send up to 255 directly to serial that is 1 byte right?
but if I convert it to ascii before send, that would be 50 53 53, 3 bytes right?
So I was thinking of sending 2 bytes without ascii covertion......
