Trouble initializing RGB camera (SOLVED: Nebula was power saving mode)

null · August 17, 2021, 4:14pm

Hey, I’m having issues accessing the RGB camera with the newest version of the preview SDK. I’ve followed the guide and tried running it on multiple NReal Light glasses and phones, so it doesn’t seem to be a hardware issues. Could anyone point me in the right direction?

The nrsensor logs read:

[INFO] [NRSensor] RGB Camera got false handle, work type = 0
[INFO] [NRSensor] RGB Camera protocol 0 MATCHED
[INFO] [NRSensor] RGB Camera protocol load SUCCESS
[INFO] [NRSensor] RGB Camera initialized
[INFO] [NRSensor] RGB Camera starting

[ERROR] [NRSensor] Generic Camera start failed

Just to cover all points. Have you disabled power saving mode in Nebula’s settings?

Which version of the NRSDK and Nebula are you using?

It was indeed the power saving mode… I must have missed that setting somehow, sorry for the stupid question.

Not at all. Glad to help

Hey, I have the same error, but Power Saver is actually disabled (I get a different error when Power Saver is on).

Any other suggestions?

Hi, is it possible to attach your log too, full log please? Also, your phone mode name and Nebula version, please.
