I know that this question has been asked before many times but not recently and the API have changed so Google might have fixed some bugs. I was thinking it might be possible with two ways.
1st: Using Bluetooth Low Energy API of Android and then use android as central mode to scan for Bluetooth devices(iPhone). That is similar to what here edoardotognoni asked, which it is seems after some seconds iPhone is rejecting him. I am still currently reading about this post and the raised issue he made but I mentioned it in case someone knows something has changed.
2nd: Using and WiFi-Direct. About this method I have not found anything but If it is possible for two Droids to connect why can't it be possible for a Droid and an iPhone to connect. I have read about that matter this answer.
I also found this example on GitHub iPhone part, Android part. Unfortunately I am not very good with xcode so I don't know exactly what is written in the iPhone part.
edit: Actually after searching I already found that it is possible with BLE but not with WiFi-Direct since iPhone does not support it. Of course being able to do it does not mean it is easy. Despite that though I have not yet found concrete proof because all I have seen is theories, an xcode that I don't understand and an Android code which seems to work when I checked it, but I have not run it.
Any help will be much appreciated, sorry for the long post!
