Questions about the STM32WB PWR and Advertising

[GS2]

Hi STTwo-32,

I have 2 more questions:

1. What jumper to remove - so the NUCLEO board will stop advertising ?

2. What to do - to change power on  STM32WB5MMG module from  current 2.4-2.6V to 3.3V ?

Thanks

Hello @GS2 

1. There is not a solder bridge or a jumper that control the advertising on the NUCLEO board.
2. What do you mean by "What to do-to change power on STM32WB5MMG module from current 2.4-2.6V to 3.3V"?

Best Regards.

The voltage on custom board with STM32WB5MMG module that comes from NUCLEO board is 2.4-2.6V 

[STTwo-32]

Could you explain more. Are you powering an STM2WB module from a Nucleo board.

Best Regards.

Yes, see https://community.st.com/t5/stm32-mcus-wireless/use-st-link-from-nucleo-wb55rg-to-flash-an-stm32wb5mmg-module/td-p/727118

For the power, try using an external source (not the Nucleo board).

Thank you, now I have more questions:

1. Why - For the power, try using an external source (not the Nucleo board)?

2. Can I use Nucleo board 3.3V for the power ?

3. Why voltage from T_VDD is 2.4-2.6V ?

4. Do you know the easy way to measure battery voltage, using ADC ?

Battery service - bas does not provide the battery level %.

You have nothing to say ???
