Operating System Changelog
When using OS 1.1.2 the Control Hub operates by defaults to the 5Ghz band. To switch to the 2.4 Ghz band without the REV Hardware Client, see the Resetting the WiFi Network section.
Adds support for Auto Channel Selection, where the Control Hub will pick the least busy WiFi channel on the selected WiFi band when it starts up
Migrates all users to Auto Channel Selection on the 5 GHz band by default.
If you find that you are unable to connect to the Control Hub after updating, you should perform a WiFi Factory Reset by holding down the Control Hub's button as it boots, until you see a colorful light sequence. That will reset the WiFi settings and switch to the 2.4 GHz WiFi band.
Allows switching the WiFi band between 2.4 GHz and 5 GHz by holding down the Control Hub's button when the hub has been booted for at least 20 seconds
If version 5.5 or later of the Robot Controller app is installed, the Control Hub's light will blink magenta when the band is switched to 5 GHz, or yellow when the band is switched to 2.4 GHz.
