Hmm... I am not sure. A write response does not contain any data of its own; all write responses are alike. Is it possible lightblue displays that due to an attempt to read a characteristic (as opposed to write)? Unfortunately I am not equipped to test this out at the moment, but I'll take a look tomorrow. That said, I don't believe there is anything wrong with your code. Chris
