Low-power modes for STM32WB5x

Greetings,We're looking into the low power modes of the STM32WB. Our measured consumption in Stop2 on our custom PCBA is very close to the expected value. However, in reset (holding the reset button), the MCU is not drawing what we'd expect.For com...

How to implement Low Power modes for B L072Z LRWAN1 discovery kit

Hello everyone,I am working on B L072Z LRWAN1 kit, in which murata LoRa Module is used having STM32L072 controller. I am trying to implement low power modes and running the example code :STM32Cube\Repository\STM32Cube_FW_L0_V1.11.2\Projects\STM32L073...

STM32WB55CE is it possible to compile ZigBee example with other tool than IAR?

Hello,I tried to build project over KEIL but there is of course problem with linking stm32wb_zigbee_wb_lib.a, keil library has extension ".lib".Next step i used Atollic and option to import IAR project - compilation failed. Compiler can't find files ...

Radio power supply shutdown

Hi,I have a project with heavy constrains on power consumption.I want to completely shut down the supply of the LoRa modem when not in use to save the needed µA.The CPU can save any context needed.The NVM module seems to be the way to go.I've seen so...

I would like to ask for help! I'm working with muRata LoRa module what contain STM32L072 microcontroller. I must connect USB to STM32L072, but I can't found correct information how to do that. Maybe someone can share schematic?

UART trames are not good

Hello I am worcking an the P-NUCLEO-WB55 and I try to communicate with a other module with the LPUART. Seeing that I didn't have any responce to my commands, I use a scope to see the TX trame.This is for example the trame of '<' (00111100) .I used th...
