But I will say "normally" it is done in software.
Basically think of a computer network. Each device has an address.
If the packet does not have your address attached then the packet is ignored.

Cheers mackrackit, so it should be possible to send data only to a designated receiver module?

There is a reason I'm asking this.....Another project

The modules have been shipped today (very efficient I must say).

Yes and no...
When data is sent it is sent everywhere. It is up to the receiver to "decode" the signal. Even data that the receiver does not understand hits the receiver.

Think back to serial comms with wires. You have a "wait" for something before the receiver acts on the data. Pretty much the same with RF. But with RF there is noise from everywhere hitting the receiver.

Dig through the app notes from these folks

Are some good one to start with.

Will do mackrackit, thanks for the info. My RF knowledge is less than my LED knowledge when I first came here right now......oh dear.

The Modules arrived today (I only ordered them yesterday) they came over from Belgium too. They are quite small (I was expecting them to be larger, I don't know why). I'll have a closer look when I get a minute / tonight.

RF is the 'Holy Grail' for me. If I can figure this one out then it's uses are nigh on endless.

Mmm............

Problem?:

I'm thinking I should have ordered the: "rfPIC software and complete documentation (on CD)"?

There was no CD in either of the boxes. I'm thinking I'm up the creek without it? Or can I get by without the CD?

Sorry I know, more questions.
