Dialog Semiconductor customer support - Battery hibernation https://support.dialog-semiconductor.com/resource-keywords/battery-hibernation en System not in hibernation when dg_configBATTERY_LOW_LEVEL reached. https://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bluetooth-low-energy-%E2%80%93-software/system-not-hibernation-when

Hello,

In the bsp_defaults.h file I find for dg_configBATTERY_LOW_LEVEL:
* If not zero, this is the low limit of the battery voltage. If Vbat drops below this limit, the
* system enters hibernation mode, waiting either for the battery to the changed or recharged.

dg_configBATTERY_LOW_LEVEL is set to (2293) => 2.8V

However if I leave my system on (no BLE activity) it will discharge the battery al the way down to 1V.
I see the define is used in sys_power_mgr.c, could it be that power management is not active? Should I enable something?
What am I doing wrong here.

- we have a rechargeable battery
- we are not using SOC
- we don't put the system into sleep mode (yet)
- charging itself works fine

Thanks.
