Bluetooth handset (beginner)

[tocs03]

I would like to build a simple bluetooth handset to dial and hang up phone calls (on Android it it is different with iOS). This is to be an assistive device for and elderly person and do not need (or want) audio (intend to just use the phones speaker and mic for all the audio). I am starting to look at the hfp_hf example and also weeBell project.[1] There is a lot of ground to cover for these projects and a lot of it is audio. Is there a simpler project out there for just the dial / hang up portions.

Am I starting out on the right track?

Thank you for the reply. Most of the Hands Free things I have seen (like this one) deal with audio. I am not really looking for audio at all and have been able to connect via Bluetooth to an Android phone with a serial connection and the Arduino IDE (not hard). I am really trying to just pick a number off an LCD with a couple of buttons and push a button to dial the number. I will let the phone itself handle the audio. Then push a button to hang the phone up. I think I am making some headway in this direction using the esp-idf (a bit of a learning curve but not too bad). I hope at some point to post the results (if successful).
