Hi, I started using Lime2 recently. I am using Openwrt with Lime2. I am powering the board using LiPo battery. I could not find a way to find the battery level. I use SSH to communicate with the board. Is there any script or way to find the battery level through SSH. Help please.

I haven't one to test, but generally you find this on sys/class/power/...  after power maybe battery/status or battery/voltage.

 

To read

cat /sys/class/power/battery/voltage

 

This path is only a sample, you have to look inside sys/class/power/ the correct one.

Thanks a lot for your reply. I could not find anything about the battery. This is a list of the folders in the path /sys/class/ the power_supply is empty.  Do you have any hints on how I should proceed?

If you don't use our kernel, this function might not be supported.If you do, check this part for reading things:

Another option is talking to AXP chip via I2C which is a bit more complicated. It was brought up once - do some forum search.
