You could let someone else take a look at it.

First, we need to define "in range"

Post code.

First mention of a 50ms delay ( I thought the title of the thread was about efficiency)
I'm bored with playing 20 questions programming
Bye.

A lot of what you ask depends on how important (or not) it is to you that other sensors don't respond to echoes not generated by their outgoing pulses.

How fast is serial comms, and how fast is the processor?

Repeat for digits which haven't yet arrived.
No.

Read your code from reply #25 again.

I'm being nice.

It's my New Years Resolution.

If I'm lucky, it may last out the first week.

Then, no more Mr Nice Guy.

For the second time today, I find myself writing "check to see if you've got at least one character to read, then read all four of them".
No,no,no.

I don't like String, so if blocking doesn't matter (and it doesn't look like it should), just call available before each read.
A fairly simple function to wrap the two should suffice.

The devices talking to each other is not too difficult, but getting the range is.
If you can tell any more constraints (can't be line-of-sight etc), a better answer may be forthcoming.

Unless you're going to expand the command set hugely, I'd stick to single letters.

Usual problem; check to see if there is at least one character to read, then read all four of them.
