1.iOS 9 introduced a new feature called “WiFi Assist, that reverts back to the mobile network when the Wifi is poor.
2.Killed background apps, and freeing up memory is completely unnecessary in iOS.
3.FM tuners are not in any iPhone models, and I can say with certainty, they never will be.
If you really are an AV Engineer working on an “App to connect with a WiFi based System”, you should read up on iOS and truly understand how it works, because currently you seem way off the mark.
And as a company you should pick technology that is in it’s infancy, and support that. Forget about trying to support FM tuners, it’s a waste of yours and your company’s energy.
I appreciate your reply, but trust me when I say that I'm not "off the mark". I've been doing pro-AV for over 15 years. I primarily do installation and Crestron programming work, but my background is in sound reinforcement audio systems and FOH engineering. I'm not sure where one would "read up" on iOS other than looking at Apple show off product pages. Is there actually an iOS manual? Or the basic step-by-step knowledge-base or ask Siri for help when you already have an iDevice?
The system I am talking about is made by Sennheiser called
ConnectStation / MobileConnect. I didn't sell it, and probably wouldn't sell it, but I became responsible for installing it. It's a low-latency live audio streaming device, putting four discrete channels of live audio on a iOS/Android device via an app. Sennheiser generally makes very good products but this device isn't ready for primetime. They don't even have English documentation ready, and the mobile app versions are 0.8.0 Beta. But somehow, it is being sold.. and it is over $7,000 for the system.
The device acts as a managed AP controller (using Rukus APs). It is specifically designed to NOT have Internet on the same network. It's not my choice, it's the product design, as flawed as it may be.
The intent of my post is to gather some info on how to help troubleshoot connectivity issues with a room full of 30+ iDevices (and Android). Out of over 15 iOS devices, there will be 3 or 4 that will constantly disconnect from the private (no-Internet) network or have crappy WiFi (cut outs, choppy audio, etc). If all iDevices are created equal, performance should be consistent across them all, especially given that they are all in the same spot and not moving around. Do iOS apps not attempt to connect to the Internet in the background? I definitely imagine that an iPhone with 30 games installed will have more background activity trying to hit the Internet than an iPhone with 2 games installed.
THIS post suggests that every iPhone and smartphone currently in existence has an FM tuner built in but Apple has them under lock and key, which is why I asked.
