Bring Zello to the foreground with a Ruggedized Device PTT Button
Zello is often paired with ruggedized devices that have dedicated external PTT and/or SOS buttons. Most users need to run other business applications on the device while still maintaining communications via Zello. One advantage of these ruggedized devices is that their dedicated PTT buttons can be used to bring Zello to the foreground.
The PTT button behavior (i.e. bring Zello to the foreground vs keep it in the background) can be configured from the Admin Console.
You'll begin by mapping the hardware button.
Then from the Admin Console, you can visit Settings > Android > General and turn on/off the Bring to the foreground when push-to-talk button is pressed.
Turn this setting on to make Zello move to the foreground, and turn the setting off to stay in the background while broadcasting.
- Turning on this setting will allow you to quickly tap the hardware PTT button to launch Zello in the foreground, then select the contact/channel you wish to speak with.
- Turning off this setting (i.e. keep Zello in the background), could be useful when combined with the default channel, as it would allow your users to talk on Zello without leaving their primary workflow application. Note that even if a default channel is not set for your network, the user can choose a default contact for themselves within the PTT button settings.
Note: Zello is brought to the foreground almost instantly with the PTT button press except when you press the Android home key. In that case, it may take up to 5 seconds for Zello to come to the foreground after pressing the home key.
Note: Customizing the PTT button behavior from the Admin Console is currently only available on the Zello Android app and works with Zello version 4.91 and above.
