Setting a Bluetooth PTT button for Android
You can set a Bluetooth button as the PTT key to use while Zello is running in the foreground.
1. Go to Zello Options
2. Select Push-to-talk buttons
3. Select + icon at lower right corner to add a button.
Press and hold doesn't work with Bluetooth, but you can use the Bluetooth button to talk under these conditions:
- The headset supports A2DP and AVRCP and has media control buttons (Play / Pause / FF / RWD)
- Enable "Toggle" under Push-to-talk Screen button action.
Then press once to start talking and press again to stop.
