Hello, I can't get a current lower than 108µA in stop1 mode. It's expected 3µA in the datasheet.I set all pin in analog input mode, disable the debug in low power mode.I try with the NUCLEO Board as explain in the article number n°2190.I also removed...

Hello,I use a stm32WB15 MCU in shutdown mode with a wake up by the wake up pin PA0 (System wake-up 1).Everything works fine with the polarity "High". I use the HAL function "HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1_HIGH)".But with the polarity "Low" a...

Hi,On a custom board I can no longer reprogram the MCU (STM32WB15) via the SWD link.The last program flashed on the card works perfectly but I can no longer establish the SWD link with CubeIde via the ST-LINK probe.Message "target not found".I guess ...

CPU2 was not in shutdown mode ! Now with CPU2 in shutdown mode (LL_C2_PWR_SetPowerMode(LL_PWR_MODE_SHUTDOWN);) current consumption is 3µA for CPU1 stop1 mode.Sorry

Hello,Please Piranha stop answering my request and instead let ST tech support do it professionally.Regards,Joël

Thanks Piranha for your response.But my question is not how to enter in shutdown mode but why with High level it works correctly and why with Low level it fail ( in this case the MCU wakes up regardless the level on the wake up pin).IHas anyone ever ...

Hello WWU.807,I would like to know if you have found a solution to your problem because I have exactly the same problem with an STM32WB15!.Thanks,Joël

Hello Romain,I tried the two commands but without success.I know that in shutdown mode the clocks are stopped exept the LSE.Actually the MCU is wake-up by the RTC every 30 seconds and it works correctly, exept that the WD link even when the the MCU i...
