Hello Vicente,

You can check KeyFobDemo project(keyfobdemo.c-->KFD_BATTERY_CHECK_EVT)

Hi,

You can check percentage from voltage level. You can sample voltage level via built in ADC in cc2541.

Sample code for it is given in battery service.

You can find battery service in :"Project->BLE->Profiles->Batt->battservice.c"

Check this function "battMeasure".

Hope this will be helpful.

Hi,

Yes, It works with CC2541.

Try to load Keyfob / SensorTag project directly to CC2541.

Check in battery service whether it shows percentage or not.
