HFP Android Nougat Tinker Board S

[okiura]

Ok...  First thank you for your answer!!!

Now with just that I'm not able to go foward. I'm looking to find walkthrough or tutorial and nothing come.

Can you give me more information?

What is your goal here? HFP and HF_Client are different Bluetooth profiles. HPF is used to connect an headset you your device, some wireless headphones use this service and it's available on the stock ROM provided by Asus. HFP_Client allows your tinker board to act as a wireless headset this not supported in the rom provided by Asus.

In my case (building a car head unit) t was HFP_Client i required along with a few other services like A2DP_Sink, to achieve this i checked out the AOSP source provided by Asus and modified to to suite my needs and built a custom Rom.

if it is HFP_Client you are after then your best bet is a custom ROM also, on a site note getting the HFP_Client service on the device was relatively simple, getting
sco working was a nightmare.
