Describe the bug

This is somewhat random, and I mainly see it when I am in Berlin (maybe due to higher LoRa traffic there?):

I usually short press the trackball to switch off the display; screen lock I have disabled, Display Blink and Keyboard Blink I also have disabled (and for debugging, set to 500ms).

When I randomly search for my device in the backpack, I sometimes see the keyboard/ display shortly lightning up (a very short ont-time blink, much shorter than 500ms).

I have the following settings:

Mgmt → UI → …

  • … Disp. Brightness: 50%
  • … Disp. Timeout: 1m
  • … UI Zoom: 100%
  • … Keyboard Blink: Disabled
  • … KB Blink Dur: 500ms
  • … KB Timeout: 10s
  • … Display Blink: Disabled
  • … Disp Blink Dur: 500ms
  • … Autolock: Disabled
  • … Autolock Timer: 60s

Which device are you using

LilyGO T-Deck Plus

Which Firmware are you using

"MC-Term", version 0.9.11.

Regards!

Fixed (v0.9.12.1)

  • T-Deck Plus UI blink: when Keyboard Blink or Display Blink is disabled, pending blink state is now cancelled both at notification time and in the runtime blink drivers, preventing random short display/keyboard flashes from queued message activity (#174).

I just close it although I can not reliably test.
