My iPhone running the SDK polls data from my Electron GPS tracker by making a function call to it.
Electron responds to this by publishing latest GPS record.
Works great; iPhone does function call and gets every GPS record.
But! If while this is going on I start a 2nd iPhone polling a 2nd Electron tracker, communication between the 1st iPhone and 1st tracker hangs.
Both iPhones have same software, both trackers have same software.
