Known Issues

General Hardware:

• Smart Connect (BYOD) Mode Unplugging Issue
  • Unplugging a Type-C USB cable when the Bar is in Smart Connect (BYOD) mode may cause the Bar to reboot. This issue is expected to be addressed in a future firmware release.
• DTEN Mate (PoE or WiFi) and Bar Disconnection
  • Try rebooting either device if the Mate and Bar become disconnected.
  • Quick Fix: Restart the Bar or Mate.
• Privacy Flap Not Closing
  • Sometimes, the Privacy Flap may not fully close after the Bar exits a meeting.
  • Quick Fix: Reboot the device to force the Privacy Flap closure during the Bar's power initialization checks. If the Privacy Flap does not close after a reboot, contact DTEN Support. 

Microsoft Teams Rooms on Android (MTRA):

• Device Information Display Discrepancy on Mate Menu
  • When a Mate PoE is upgraded to AOSP-compatible firmware and paired with a Bar, the Mate PoE's Menu Device Info page may incorrectly display the Microsoft Intune version and Microsoft Authenticator version information for the Bar.
  • Quick Fix: Upgrade the Bar to AOSP-compatible firmware to align with the Mate PoE's updated firmware.
• Teams Main Interface Displays Black Screen During DTEN Orbit Mission Control (OMC) Session
  • When DTEN Orbit Mission Control (OMC) is used for remote assistance by DTEN Support, the Teams main interface may appear as a black screen on the connected remote PC. This behavior is due to a newly implemented security policy within the Microsoft Teams application. 

Zoom Rooms on Android:

• Zoom Security Timeout
  • The Bar will disconnect if the Mate (Poe or WiFi) and Bar aren't connected within 10 minutes. You'll see a prompt on the Mate (Poe or WiFi) to reboot the Bar manually.
• Loop reboot issue
  • A low probability loop reboot issue occurs after a system upgrade.
  • Quick Fix: Power cycle the device.
