I need some way to control iPhone 5 to allow me use a external microphone in the headphone 3,5mm socket and output my voice (in real time) to an external bluetooth speaker via the mobile Bluetooth system in the phone. In fact it’s like using a mobile phone as a PA system. Can anyone help?

As you plug in external microphone your system should switch to that input, same for the Bluetooth speakers as output.
