Advanced network settings:
This is where you can change network parameters, do troubleshooting, and fine-tune app performance.
Enable asynchronous message delivery: When enabled Zello will let you record message immediately after pressing the button, and deliver message asynchronously while minimizing delay. When disabled, Zello establishes connection first, and then stareams the message. You won't hear ready to send beep until the recipient's device responses. Most users should keep this setting on, disable it only if you want to make sure the communication is strictly live.
Enable call pre-setup: This minimized delay for repeat calls to the same contact by sending frequent keep-alive packets during the 1-1 conversation. Disabling this setting may improve battery life at the expense of less predictable delay.
Networking (mobile)
Changing these features go into effect when you’re connected through your phone’s mobile service.
Keep alive interval: This is the polling time between the app and the service. A longer time polling time uses less bandwidth and improves battery life. A shorter polling time keeps the user status display current and may improve connectivity. For most, the default value should work fine. Options are s for seconds and m for minutes.
Use TCP only: Using TCP instead of UDP speeds sign in and improves connection reliability. But it may delay receiving messages in real time.
