I want to measure current draw on a Nucleo-WBA65RI board using a Nordic PPK2 power profiler. I put the PPK2 in ammeter mode across JP2 of the Nucleo board, and loaded the BLE_Power_Central example in IDE. The Nucleo board is being powered by the USB connection st-link. This is following STM32WBA Bluetooth® Low Energy – Power consumption applications - stm32mcu
When the firmware runs, I see around 4mA drawn for the first 10s setup time. The the red led goes out, as it enters the measurement time, and yet I still see a current draw of 4mA.
What do I need to do to truly measure the current draw of the stm32wba65?
