Glasses disconnect after several seconds to minutes

wilcoboode · December 6, 2023, 8:53pm

Hey , im getting an error after several seconds to minutes, after which the glasses disconnect. It happens with several of the sets i have (so far 3 out of 20), and it happens both in my own apps, and the Nebula Menu:
Is there anyone who knows what the issue can be? I attached the full log from one of my apps to show the error I get.
I expect a bad DP port on the phone, but am not sure. It would be great if someone can help me figure out what the reason is, and if it can be fixed.

Hi, can I know what phone model you used for testing? And the built-in Android system version. Thanks in advance. From the log you provided, it seems like the USB signal is stopped in a sudden.

Hi, we are using Oppo find X3 pro, with android version 13.1 and the latest nebula update.
The issue appears with some, but not all our devices.

wilcoboode · December 7, 2023, 6:31am

Extra info, the phone does not seem to disconnect from other devices, like a computer, only from the xreal light glasses we are using.

Please go to the Settings menu of the Oppo phone. In the Settings menu, select the ‘Apps and Notifications’ option. Within the ‘Apps and Notifications’ option, find and select the Nebula app, and turn off the ‘associated lanuches’.
After that, restart the Nebula app and launch your developed app.

We found a quick workaround. If we tape off the proximity sensor then the devices continue to operate (even the ones with consistent issues before).
Well try the other option later as well, but for now it seems to be a proximity sensor /sleep / hibernation issue
