This realvnc has been a revelation using a raspi2B at the sending end and a ZeroW at the viewing end, both viewing and controlling the serving end from terminal. The sending end raspi2 has no speakers, keyboard or mouse. We should like to play alarm signals on our hdmi speakers at the viewing end, preferring the recorded wav or other file to be stored at the viewing end. We've tried a few blind-leading-the-blind more-in-hope-than-anger quirks but with no success to date.
So . . .is it possible to do this? If so, what How-to do we need to read, please, or, preferably for anyone who has done it, using python, what python code was used?
