Doodle Channel Selection

Channel Selection

Unlike the Herelink radios that automatically hop channels to avoid interferences, the Doodle radios operate on a fixed channel.

It is important to select an optimal channel to maximize radio range and performance.

Astro's Doodle radios operate on the 2.4 GHz band, which is also commonly used by other WiFi systems. By default, units are shipped from factory with channel 3 selected. This is a channel that avoids most of the typical WiFi routers.

How to scan and change channels

  • Go Pilot Pro App > Radio Settings > Channel, then press "Start Channel Scan"

  • After the app starts scanning, a visual is displayed after 5 scan samples, and continues to scan.

    • It is recommended to run the scan for up to 3 minutes for accurate results.

    • Losing connection is expected when scanning/changing channels.

  • After scanning, the best channels available in the current radio space is highlighted with green.

  • Tapping on any of the channel numbers will initiate a channel switch.

    • It will take up to a minute for the system to change channels on both sides and confirm that change has been applied successfully.

  • To stop scanning, do one of the following: Change a channel, stop scanning manually, go to a different menu, or exit app. This will take a few seconds.
