Serin/out interference
Sorry, I should have mentioned this before, but I want to be able to
communicate wirelessly with two pairs of Linx Technologies HP
transmitters/recievers. Has anyone ever dealt with wireless stamp
applications? Thank you.

I have used the Parallax RF modules and Rentron's TWS/RWS modules for some
time. How can I help you ?

series from Linx. I hooked a BS2 and BS2SX directly together with a
ground wire and a data wire. I sent "HELLO!" out of the BS2,
recieved it with the BS2SX, and debuged it on the computer. It
worked fine. When I tried sending it wirelessly(with the same
program), however, I got junk that certainly wasn't HELLO! This is
my first time using the HP series. Do you know what I'm doing wrong?
Thanks again.

data. It may need to be inverted.
Good luck!

Let's look at the program considerations first.
To send from one Stamp to the other you write:
serout 0, N9600, [noparse][[/noparse]"Hello"]. That transmits it.
Now then, "Hello" has five bytes, so you have to set up the receiving Stamp
for exactly that. So then you write:
serstring var byte(5)
serin 0, N9600, [noparse][[/noparse]str serstring\5]
You can't debug the receiving Stamp unless you have a separate PC connected
to it. OK sso far ?
