Hello
I was developing an application that uses BLE and low power mode. I was testing that on a custom board and when I measured the current consumption at STOP2_MODE, it was 1.7 mA.
I expected that I had made a mistake. So I tried the low power examples found there STM32CubeWB/Projects/P-NUCLEO-WB55.Nucleo/Examples/PWR at master · STMicroelectronics/STM32CubeWB on my board and then using the P-Nucleo-WB55 and I found the current consumption is above 4 mA.
Shouldn't be measured in micro-ampere? I am confused now, as I am using an ST example and a dev board, so it should work well.
Thanks in advance.
Best regards,
Mahmoud A.

Hello,
before measurement with NucleoWB55 please remove everything from JP5 and JP2, also remove USB cable from ST-Link during measurement.
Please let me know if you can reach the stop mode current, thanks.
