Re: Electronics - how to send text/data over rf comunication

["Dave McLaughlin" <dave@xxxxxxx>]

A tx/rx (ie both ways) option is going to be expensive. I have built a 1
wa=
y
comms link using the low cost SILRX and TX modules from RF Solutions.

These need to have special software to encode the data stream as they
don't=
line NRZ (Non Return to Zero) data such as that from the PC's serial
port.<=

They do have modules that take RS232 but not for the =A315 you want to
limi=
t
it too.
