Setting the PTT button for an Android Bluetooth accessory

Starting with Android version 3.67, we've simplified the process to add accessory and device buttons. 

Adding a PTT button:

1. Using the manufacturer's instructions, pair your Bluetooth device to your Android phone
2. Tap open the App Menu (3 vertical dots)
3. Select Options
4. Select Push-to-talk buttons
5. Tap the Add (+) icon at bottom right corner
7. When prompted, press the button on the accessory to use as the PTT button
9. Test the button by using it to send a message to your Echo contact on Zello. 

IMPORTANT: Support for A2DP Bluetooth profile required by Zello. Compatible headsets are most reliably identified by A2DP support mentioned in headset specifications.
