hrh1818, you've mentioned this in the other thread but I still don't understand how that would work. How do you tell the coordinator which Arduino to communicate with?
08-21-2014 05:17 PM
Yes, our system would be somethis like this:
In LabVIEW, having a different ports (COM) wouldnt that communicate with the coordinator already?

Your question "In LabVIEW, having a different ports (COM) wouldnt that communicate with the coordinator already?"
A COM port is a hardware serial interface to an external device. The XBee coordinator has only one hardware serial interface. There is no physical means available for connecting additional COM ports to the coordinator.

hrh1818, how would you be able to specify which node you are talking to with LIFA? From what I read, you would need to be in API mode. I saw a Java API for working with multiple Arduinos but that doesn't really help here (afaik).
This is a critical step in his developement and if it can't be done relatively easy then it should probably be known ahead of time.

Yes. This is not possible for LIFA? How will the Xbee coordinator get the data from each arduino xbee nodes. To one coordinator the to the labview?
Knowing that one-to-one communication is really possible. What I need is how will I be able to to a muliple-to-one communication?

The short answer is XBees can be connected in an network and uses a address similar to the way the Inernet uses an address to ensure a message goes to the right location. In this application a star network is being used.

So meaning it is possible? How will get the data from xbee in base station. I mean how will i know if itnis from node 1,2 or 3? If possible can you show it to me from my uploaded labview?

I wonder if LVH LINX would work in multiple to one communication for this system?
08-24-2014 02:53 AM
Neither LIFA or LINX are designed to work with multiple Arduino's on the same "Xbee network" unfortunately. So, neither one will work for you without serious modifications (I'm assuming it's not a simple modification).

Any idea on what I should modify? Or what I should do?
But it is possible to have multiple arduino "Xbee network" but not using LIFA?
