Topic: How to / Can I limit the range of XBee series 1? (Read 552 times) previous topic - next topic

Hi,

I'm looking to limit the range of XBee Series 1 down to somthing like 2 - 3 meters. Is this at all possible? Reason being is that I need to create a simple P2P network based on proximity for an interactive art installation. So basically the different objects ( there are 9) will each have an arduino with code that will only run when receiving a certain letter. The letters are then transmitted via the XBees of the other objects. So each one will be sending a letter as well as have a piece of code to run.  By limiting the range I can ensure that the code will only run when other objects are within close range and each will have it's unique ID.
Is this at all possible? Or is there a better way to do it?  All other systems I have read about, like using Beacon and active RFID, or different sensors systems seem rather complicated.

My skill level is basic to intermediate: I've worked on quite a few arduino based art projects but nothing to complex.

I really appreciate any input.

Perhaps you could use a cheap low power  transceiver module with nothing connected to the antenna pads ?

Some forum members have complained of only getting a few meters range when testing without an antenna.
With my mobile phone I can call people and talk to them -  how smart can you get ?

hi Boffin1, sorry for taking so long to respond - you mean something like this https://www.sparkfun.com/products/10532?

you did say interactive, do you need duplex ( 2 way )

if not a simple Tx and Rx module should work fine.  Hope make some cheap ones.

yes i do need two way - each object in the installation runs a piece of code activated by the proximity of any other object, which in turn also runs a piece of code, etc.

to clarify: the code is only activated by the proximity of any of the 8 other objects, not any other object..

So you will need a transceiver then, I dont know offhand which would be suitable, but I have seen some adverts for micropower modules.

Good luck
