CC2650RC: CC2650/CC2640 Voice remote control for support on Android device.

Part Number: CC2650RC

Hi,

I have flash cc2650rc default image to test HID profile and there is a MIC button....but the voice protocol seems TI specific not working on Android device.

You can see: https://www.ti.com/lit/an/swra506/swra506.pdf

in https://source.android.com/compatibility/android-cdd.pdf page 11.

We can support long press media playback to launch Google assistant .

But no way to send voice data to this...

So do we have sample protocol to support voice data on Android device?

Hi,

Thank you for reaching out.

Could you please tell me if you properly manage to send voice data in some other cases?

Could you also point me to the place you have downloaded the code and the version you are using?

Best regards,

Hi,

Sorry for my late reply.

I download the image from here:

BLE-STACK — Bluetooth Low Energy software stack. So CC2650RC is working well.

Then I saw a perfect demo to me which is exact what I want except its on Linux: https://training.ti.com/zh-tw/voice-over-ble-demo?cu=1134134

And we should be able to test on Linux/Windows with this script:

https://github.com/ti-simplelink/ble_examples/blob/simplelink_cc2640r2_sdk-2.20/tools/scripts/voice/voice.py

Even CC2650RC has correct key to invoke Google assistant on Android platform, we still cant cant transfer voice data to Android.

The reason is Android doesn't standardized the voice over Hid over Gatt.

Just normal keyboards mouse , joystick subclass...etc.

https://developer.android.com/reference/android/bluetooth/BluetoothHidDevice

So just need to implement Gatt-server base for this on Android or try to run python on Android(this may need to customized Android system).

Thanks for your support.
