NRF52: Receive/Disconnect calls, control volume +/- on Andriod

[Amit]

Hello,

I am completely new and I am having NRF52 series.

I would like to know is there an ready example for android or iOS phone using Bluetooth:

• Control volume (increase and decrease volume of phone just like volume control on phone)
• Receive/Disconnect calls (pick incoming calls and disconnect once done)
• Play and pause music player
• Previous << and Next >> control

All above function through buttons on NRF52 kit?

Thanks

The ble_app_alert_notification example shows how the nRF52 can work as a client, meaning that the central (smarthpone) will be a server that can push data (incoming calls) to the nRF52.

This example on github shows how to control volume.
