So I just replaced an Arduino Yun with my 2nd Spark Core, and I love it. My first Spark Core project taught me enough to do a quick swap out and it works beautifully.
So of course I’ve decided to complicate things. I would like to sync several devices using a single Core as the “traffic cop/orchestrator” - right now I don’t want to try and issue commands to the 2 separate spark cores and hope they are timed roughly the same, because I expect there will be normal latency and hiccups.
I thought I would use one Spark Core as the gateway to my UI layer, and then have that spark core communicate with several controllers nearby via short range wireless of some sort. At Maker Faire I talked to a guy about Flutter Wireless, and I’ve read about XBee and even older school 433mhz RC car type controllers.
Wondered if anyone has any experience using the core as the hub of a mesh network, where the commands happen locally and the Core just has to connect it all to the internet. What hardware works well with the Core? What’s the best thing for a master controller-many slaves arrangement?
Any help is appreciated!
