I'm attampting to control 10 Arduino UNOs with Etherner Shields by a central computer. I've attempted to use the CIAO app on my iphone (ideal solution), but that appears to have a problem where I can see the Arduinos, but loose commication to all but one.
Here is the outline of the project:
I am controlling a pnematic system to open gates. As the livestock pass a certain point, I need to open a gate to allow them to proceed forward. This is all done manually now, close rear gate, then open a forward gate, depending on where I need them to go.
The entire stock yard is covered with ethernet and wireless. That is what I want to use to communicate witht he Arduinos.
More about the problem I am having with CIAO. A discovery of the Bonjour service shows a device with mutiple IP's listed. I've tried the idea of changing ports for each Arduino, and ensured that they have different IP's and MAC address's. I have the idea that the name of the board is the conflict. For those that know Microsoft Windows it's like having 2 computers on the same network with the same name. ??Does Bonjour look at the broadcast name as well??
Any help or thoughts would be great.
