Can we control the play/forward/reverse/pause functionality of the headset using Bluetooth smart module present on wristband through music APP installed on the smartphone? or Do we need AVRCP bluetooth profile to be present on wristband itself.?

Hello ,

I'm Dinesh Katkar,We as team planning for wearable IoT product,so selected Nordic sem's Bluetooth Smart SoC for our end application.

Can we control the play/forward/reverse/pause functionality of the headset using Bluetooth smart module present on wristband through music APP installed on the smartphone? or Do we need AVRCP bluetooth profile to be present on wristband itself.?

I would like to check that AVRCP profile is available for Bluetooth Smart. If so, how I will need to use this profile in your embedded software in order to communicate with your host.

Thanks Dinesh Katkar

There is no AVRCP profile available for Bluetooth Smart.

I would look into using HID over GATT to do this, there are some related questions in there. For example this.

Or you could use a proprietary profile and let the app implement the actual functionality. Then I would recommend having a look at the ble_app_uart example.

1. If you use HID over GATT the existing music app would not need to change. If you use a proprietary profile the music app would need to change to interpret the commands received from the wristband.

2. A proprietary profile is a profile you define yourself, so it is not a profile define by the Bluetooth SIG. It is not AVRCP profile of Bluetooth, because that doesn't exist for BLE. ble_app_uart is an example of an proprietary profile.
