Mapping a hardware button to a specific contact or channel
Zello now supports mapping a specific user or channel to accessories and device buttons on Android.
When configured the selected hardware button will always call the same predefined channel or user. To call on a different channel the user will need to use a screen button. For more flexible configuration use the Default contact feature.
To map a contact:
1. Go to the Zello menu>Options>Push-to-talk buttons
2. Select +Add Button
3. Press the hardware button on your Bluetooth accessory, wired headset, or Android device button (for example the volume keys).
4. The button should be listed now. Select the button to be taken to the button details page
5. Tap Button Contact>Select... to choose a default user or channel
That's it! You can test your button.
Note: Standard device buttons (such as the volume keys) only respond when the app is running in the foreground.
