Measurement of current consumption

[Nour]

Hello everyone,

I want to measure the current consumption on a STM32WB5MMDK discovery board. I've found that I had to put an ammetre on the jumper JP1, and I programmed the RGB LED to be working. However, when I put the ammetre and I power my board, I found that the current is null, and I can't find why, even if I checked the schematics and the datasheets. I was supposed to have something around 100 mA normally.

Does anyone know the reason of my problem ?

Thank you

Nour
