mido Posted April 1, 2018 Posted April 1, 2018 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.
leomecma Posted April 1, 2018 Posted April 1, 2018 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.
mido Posted April 1, 2018 Author Posted April 1, 2018 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? ata_device block gpio i2c-dev mdio_bus phy pwm scsi_host udc ata_link devcoredump graphics ieee80211 mem power_supply regulator sound vc ata_port dma hidraw input misc ppp rtc spi_master video4linux backlight extcon hwmon lcd mmc_host pps scsi_device thermal vtconsole bdi firmware i2c-adapter leds net ptp scsi_disk tty watchdog

It was brought up once - do some forum search.
