Is there a way to pair and connect programmatically to a remote device in Hands-Free-Profile (HFP) mode?

So far I am able to just connect to the remote device in the normal way through code. I require to connect to the remote device in the HFP profile mode.

I don't really understand what you are trying to do here. HFP is a profile, once you have a BT pairing and connection, you can then connect the HFP profile.

HFP itself is not used for pairning.

This is where HFP fits in to the whole of things (from official BT specification HFP_1.6)

enter image description here

There is more information on how to initiate the Service Level Connection in the official documentation Check page 19

In order to do so you need to implemet the whole Hands Freee communication profile (HFP). Here you can get the UUIDs for Bluetooth server socket identifiers (you need Handsfree and Handsfree_AG) https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/BluetoothUuid.java

Here is a specification of HFP that you must implment: https://www.google.co.il/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwimg6i597bPAhVMXRoKHRUJA2EQFggiMAE&url=https%3A%2F%2Fwww.bluetooth.org%2Fdocman%2Fhandlers%2FDownloadDoc.ashx%3Fdoc_id%3D292287&usg=AFQjCNHB_Z4ResJYu7IY5ijZADbGB7Telw
