iOS - Connecting BLE device to app and iOS

Question

Is it possible for a BLE device to be connected to an iOS device using Bluetooth classic (via settings) and also be connected to the same device using BLE via an application?

Answer 1

Yes. You can for example use A2DP music streaming by connecting via the Settings menu and establish a concurrent BLE link from your app. Some versions of BT chips have restrictions, though, that prevent you from being a BT Classic Slave and a LE Peripheral at the same time. For these chips, BT Classic Slave + LE Central should work fine. From the iPhone side, it's no problem.
