Hi,I am currently doing some tests measuring the battery voltage on a system using the STM32WLE5, I am measuring both v_sys and v_bat. I am running into an issue with the v_bat measurement, I am seeing alot of noise compared to the v_sys measurement....

I am using an LPTIM1 with a 64 Prescaler and a count of 15360 which, with an external 32.768kHz watch crystal, gives a 30 second period. With an IWDG with a Prescaler of 256 and a 32kHz gives 32 seconds. The device should go into STOP2, wake up from ...

I am using the VBAT pin to measure the voltage of my battery, but the readings I am getting through this pin are always off by about 3%. The datasheet (https://www.st.com/resource/en/datasheet/stm32wle5cc.pdf#page=120) claims that there could be +-10...
