Is any sample code for ADC VBat channel for STM32WB nucleo board? I leverage sample code from 1.13.0, 1.14.0 and 1.15.0 and change IOC to set internal channel VBat, but not work. thank you.

Hello @LChan.5​ 

You can start with some examples in STM32WB FW package then you can switch the input channel to ADC_CHANNEL_VBAT
