Hi again Dave

I think I am almost ready for the next step ....
RF and RF module TX RX
I have been reading posts all through the forums, even some of yours from years back ...
Now for the next step ... to try the same or a similar thing without the wires.

Should I start off with sering or plunge straight into HSER ?

The plan is to be able to send 3 bytes using the most reliable method.

So the question is where do I start and what do I start with ?

Kind regards
Dennis
