Zello Android VOX Support

Intro

Zello is frequently used to link two-way radios with mobile phones or computers via the Internet. TX and RX is usually controlled using VOX, which is NOT ideal, but very simple to implement. (You just need a passive cable)

Of course, VOX must be supported and configured on both sides; Zello and two-way radio transceiver.

VOX feature in Zello

Is only available in desktop PC app, which makes the whole system very complicated, vulnerable and a little more expensive.

For PC setup You need:

• PC w/ Windows
• License for Windows
• UMTS/LTE modem
• Router w/ USB modem support
• Audio Cable
• Two-way transceiver
• Low-noise power supply

Luckily, Zello is available for Android. Unfortunately, VOX feature is NOT available.

For Android phone setup You need:

• Android phone
• Audio Cable
• Two-way transceiver
• Low-noise power supply
• My naughty workaround to enable VOX feature

TLDR --->> Enable VOX for Zello Android app <<---

Step-by-step:

• Open Android Market and download application "Automate"
• Tap on menu icon (three gray vertical squares), tap "Import"
• Import this workflow (click to download)
• Tap on workflow called VOX, tap start
• Open Zello app, open contact where You want to broadcast. (screen with large MIC button)
• Test it like me on Youtube
• If it works don't touch it. Get away, leave it alone. OR Send me a message, try to fix it ;))

Final setup: https://www.youtube.com/watch?v=n8xn8kWucDk

Troubleshooting

Check these:

• Automatic screen locking
• Insufficient permissions for Zello and Automate
• Automate sleeps in background

How I managed to make this work ?

Here is some official documentation:
