We are looking for an expert on iOS Bonjour, GDC web server, and SQL Lite.
We have developed an iOS app (using Xcode 7.3.1) that allows the iPad app to communicate and send SQL Lite data with each other between two or more iPads.
At the moment this works fine but we are having issues when we put the iPads to sleep and bring them out of sleep as follows:
If we leave the app running and focused on the iPads and then press the iPad power button to put them to sleep, if we leave the iPads sleeping for 2 hours or more, when we press the [Home] button on the iPads to bring them out of sleep mode, our app is now frozen and locked up and will not respond to any touch input and eventually the app may crash, or you have to terminate the app and re-launch it to get it working again.
We only have the above problem when the iPads are left asleep for a few hours or more, if you put them to sleep and bring them out of sleep in less than the 2 hours the app responds correctly and is not locked up.
We have done the test with the iPads being plugged into the power and have tried it with just battery power (100%) but this makes no difference at all.
We need a programmer that can visit our office (near London) to spend some time with us going through our source code to resolve the problem.
Please give us your hourly rate to do this, but it is very important you have expert knowledge with Bonjour, GDC web server, SQL Lite and Xcode 7.3.1.
