STM32 MCUs Wireless

I want to power my STM32WB30 MCU from a coin cell. Can anyone provide me with a circuit of some sort to do so. I am beginner with this and don't have any testing equipment to test the circuit so a circuit or schematic would be really helpful.

How to use USART1 to send/receive data packets (for serial application) and LPUART1 as Virtual COM Port in STM32WB5MMG-DK?

Hi,I am using STVM32WB5MMG-DK for my project development activities.When I referred the user manual "UM2825", I came to know that the STM32WB5MMG USART1 interface is connected to the UART2 port of the STM32F103 ST-LINK/ V2-1 MCU.Is there anyway that ...

How to reset the P-Nucleo-WB55 to original and what are the possible problems with the sample code (BLE_HeartRate)?

I am new to this area and I just bought two P-nucleo-wb55 boards. When I used the p2p server example, it can work properly and I am able to use my phone to control the on/off of the led. However, when I tried with another sample 'BLE_HeartRate', it c...

How to provision LoRa devices?

STM32WL55 family devices need unique credentials on a chip-by-chip basis. These include DevEUI, AppKey and AppEUI, as well as Region etc.What strategies are there to permit this provisioning during the manufacturing process?I am thinking of this proc...

Assuming the manufacturing was done correctly, are there any I/O connections that would cause a 3V3 short?

The module that was used on this PCB was the STM32WB5MMGI/O was connected according to the datasheet attached for STM32WB55MMGShort found on 3V3 on 6 out of 6 sample prototypes. When module was desoldered from the PCB, the short went away on both PC...
