In the datasheet of STM32WB5MMG, BOOT0 does not need to connect pull-up resistors and pull-down resistors, just connect GND or VCC directly.In STM32WB5MM DK schematic，Do swdio and swclk need to be connected with pull-up or pull-down resistors? I wan...

What mode can I put my mcu in to consume the least amount of power but still have the ability to "wake up" after an event has been triggered?

I have a stm32 mcu. I want to put it in a very low power mode until an event triggers it to wake up. What mode can give me the lowest power consumption? whilst still being able to accept an event to wake up? and what sort of power would that draw?

Resolved! Why if I set number of characteristics greater than 1 into STM32WB55 BLE service, I can't find the device with ST BLE Toolbox?

I have a characteristic1 as a write and I want to add a second characteristic as a read, but when I add this second I can't fint the device with the App?

Unable to flash wireless stack to nucleo WB55RG

I am trying to do some testing with the new Matter protocol and using Thread and BLE on the Nucleo STM32WB55RG. Installing the new wireless stack firmware (found on the STM32 GitHub Hotspot), went just fine. After using the nucleo for a different use...
