Hal Layer polling not working

aravinthkumarja — Fri, 05 May 2017 07:31:36 GMT

Hi All,

I'm using light sensor in Android 6.

If i'm giving

=> cat /sys/class/i2c-dev/i2c-1/device/1-0045/iio:device0/in_illuminance_input

I'm getting current lux value. same value updated on android application also. But in application it's not updating continuously.

When ever i'm giving the "cat /sys/class/i2c-dev/i2c-1/device/1-0045/iio:device0/in_illuminance_input " in that time only it's updating.

What can i do to poll to read the data continuously???

Regards,

Aravinth

I fixed this issue. I did some changes on opt3001 light sensor driver code. Now it's working fine.

Thanks,
