Solved - Unrecognised serial characters received from display after touch event

Hi there. New to Nextion displays. Building a pump controller that needs a touch display. Using Pic Micro. I have it sending characters to the display fine and am working on the touch strings coming back. I have a buffer that captures the received characters and it contains: 0x65 0x00 0x0A 0x01 0xFF 0xFF 0xFF which are all what I expect. Then I get 0x74 and 0x75, which I don’t expect and I can’t find them anywhere in the documentation. Sometimes I get 0x75 and 0x76 instead. Anybody seen this?
Thanks,
Glenn.

In the Nextion Editor I had a tick on Send device ID, so the display was doing exactly that after a touch event.
