Continuing the discussion from USB or Bluetooth Keyboard input lag in Android apps (idling?):
It seems even with the new release this problem still occurs. Both ConnectBot and Termux exhibit lagging keyboard input. Display updates seem to lag about 2-3 keys behind.
Please let us know if there's some way to overcome this input/idle lag.
Thank you.
@paklnet Does this only happen when you're SSH-ing using these Android apps? Does it happen if you run, for example, a text editor that you'd also find in F-Droid?
It happens when running Linux terminals locally even without SSHing. If there’s a particular APK you’d like me to try let me know.
Thank you.
@paklnet I don't think I understand. Notwithstanding the SSH applications, are you saying that any HID-enabled control peripheral introduces latency at the OS level when supplying input?
Hi @paklnet, any additional info you can provide on the question above? Thank you for your post.
Hi there -- I just installed 1.1.0-dev and can confirm the issue is still present -- even on non-SSH applications. For example:
The updating will eventually stop, especially if controller's ray is outside the Android window.

I can't make a blanket statement for "any" HID-enabled control peripheral, only for the two USB keyboards I have tested as well as the bluetooth keyboard I tried.
Furthermore I think it's probably not right to call this introduced OS-level "latency" or "lag" as I called it earlier because the output/updates pause entirely. They're not slower, or delayed -- the window is paused or frozen.
To get the console window to update, it requires additional keypresses or sometimes moving the Magic Leap ray back into the window — this wakes it back up.
This appears to be resolved in 1.1.0!! Bluetooth keyboard input is very smooth to ConnectBot and TermUX.
