My project requires that the core can communicate to an iPhone app and other cores offline. I was hoping to achieve this through WiFi communication through an offline LAN, but I’m not sure how to set that up. I was wondering if anyone has any ideas on what this system will look like and can point me in the right direction, I imagine it would require a router that all devices connect through. I think the cores would all act as TCP servers/clients. The firmware Spark.publish() and Spark.subscribe() is exactly the sort of communication I need between cores, however it needs to be done offline. The iPhone needs to be able to set preference settings to the cores, I imagine this can be done through TCP connection.
Any thoughts on how I should proceed and pointers into the right direction would be appreciated. Is something like this even possible with the spark core?
