Control Hub Operating System Changelog

When updating from OS 1.1.1 or earlier to OS 1.1.2 or later, the Control Hub will switch to the 5 GHz band, regardless of the previous Wi-Fi band setting. Some devices do not support 5 GHz Wi-Fi, and will not be able to connect to the Control Hub wirelessly while it is using the 5 GHz Wi-Fi band. To switch to the 2.4 GHz band without needing a computer, see the Changing Wi-Fi Band section.

Version 1.1.3 - Latest Version

  • Adds support for new alternative built-in BHI260AP IMU on Control Hub
  • Improves reliability of the Wi-Fi access point monitoring feature

Version 1.1.2

  • Adds support for Auto Channel Selection, where the Control Hub will pick the least busy Wi-Fi channel on the selected Wi-Fi 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 Wi-Fi Factory Reset by holding down the Control Hub's button as it boots, until you see a colorful light sequence. That will reset the Wi-Fi settings and switch to the 2.4 GHz Wi-Fi band.
  • Allows switching the Wi-Fi 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.
  • Continuously monitors the Wi-Fi access point status, and will attempt to restart it if it goes down for any reason
  • Continuously monitors the Robot Controller app, and restarts it if it crashes or hangs (requires version 6.1 or later of the Robot Controller app)
  • Allows the Robot Controller app to access the current Wi-Fi band and channel
  • Always backs up the FTC Robot Controller app data before it is uninstalled, in order to preserve Wi-Fi settings
  • Improves Wi-Fi reliability
  • Prevents issue that could cause device to boot into recovery mode
  • Enables use of mouse button in recovery mode

Version 1.1.1

  • Fixed bug where Wi-Fi access point would sometimes fail to start after an Operating System update
  • Stopped the FtcAccessPointService UI auto-starting on boot
  • Allowed Wi-Fi beacon rate to be changed by the FTC Robot Controller app

Version 1.1.0

  • Improved reliability of making changes to Wi-Fi access point settings
  • Updated to latest Realtek Wi-Fi driver
  • Increased Wi-Fi beacon rate to 6mbps, which reduces congestion when many Control Hubs are being used in an area
  • Enabled 802.11w, which prevents Wi-Fi deauthentication attacks when the Control Hub is used with a client device that also supports 802.11w
  • Added WifiLog.txt file for debugging and disconnection analysis
  • Improved reliability of FtcAccessPointService UI (accessed through an HDMI monitor)
  • Added 5 GHz channels to FtcAccessPointService UI
  • Ensured app data is not lost when installing a Robot Controller with a different signature via the Manage webpage
  • Fixed issue where Wi-Fi SSID would sometimes be AndroidAP
