How can evaluate remote control media and call for nRF52840?

Bilgin

I am new at Bluetooth. I want to design remote media control(volume up,volume down, play/pause, next track,previous track) and call answer or reject. I have tried to make with HID protocol but this case I can not answer or reject call and screen keyboard had been invisible. I have nRF52840 Dongle. Do you have any advise to make it with BLE? Thanks for your answers for now.

    Typically when you connect a BLE keyboard to an mobile phone, then the native on-screen display is disabled while connected. So you will need to disconnect the keyboard to get the native on-screen display back.

    To call and reject calls, you would need to to check with the mobile operating systems if they allow this. I don't expect this is possible using HID, instead you may need to create an app on the phone that can connect to the BLE peripheral device, and use custom services and characteristics to handle calls though the app.
