Sensorservice in tizen wearable web api is not working when display is off

Hi

I'm developing app sensing acceleration, gyro, magnet, UV, light, pressure and HRM in gear S.

Recently, I found that sensor api is not working when display is off

When I called sensorservice.getDefaultSensor, it worked well though display is off

But when I called getSensorData (ex: getLightSensor) at off-display, Unknown error is occurred

And sensorChangeListener is not called when display is off

It happened to sensor api only, HRM or devicemotion(acceleration and gyro) is not

How can I solve this problem without always-on-display?

Hello,  try turning on the background mode, you can find it here:

YOUR PROJECT > config.xml > Tizen > background-support > enable

 

Also add this line in you code:

tizen.power.request("CPU", "CPU_AWAKE");

I tried that already, but it didn't work

 

I think this problem is bug or intention

안녕하세요 기어 S3 센서데이터 (조도, 기압등 )를 수집하는 앱을 만들고 있는데 저도 마찬가지로 화면이 꺼지면 데이터를 가져올 수 없더라구요 혹시 이문제를 해결하셨나요?? 지나가다가 질문 남깁니다.
