Clarification on HSE Load Capacitance formula in AN5646 (STM32WL55) with Series Capacitor

Hello ST Community,I am currently designing a board based on the STM32WL55 and I am aiming to optimize the BOM by utilizing the MCU's internal programmable high-speed capacitors, avoiding external load capacitors for the 32 MHz HSE.I am referencing A...

Resolved! STM32WL5MOC LSE 32kHz accuracy

Hi, In the STM32WL5MOC datasheet I can find the 32MHz TXCO HSE accurancy, but not the LSE 32kHz RTC clock accuracy. Could someone look into this and provide the min/max values similar to TXCO characteristics in Table 10? Best Regards,Dave

STM32WL55JC1 – Sigfox_PushButton example fails in E2P_Init()

Hello ST Community, I am working with the NUCLEO-WL55JC1 and the official Sigfox_PushButton example. When running the application, the firmware consistently fails during EEPROM emulation initialization. The execution enters E2P_Init() and stops very ...

Resolved! STM32WBA52 Standby Mode Example

Hello all,Anyone successfully implemented the Standby Mode for STM32WBA52/55? I am struggling going thru the examples and I wouldn't be able to enter the standby mode level. My board still consume about 70mA when I enter the standby mode. From the...

Resolved! Can't Program or erase NUCLEO-WL55JC1

I have just received 2 NUCLEO-WL55JC1. Upon connecting either one of them via I see The Red (main power) and green LEDs on. The other thre are flashing alternatively (red, orange, blue). I haven't changed the default jumper settings.The following deb...

Equivalent to SHCI_GetWirelessFwInfo in STM32 SWBA to obtain the stack version

Hi, team I previously worked with a SWB (dual core) microcontroller, and I was able to obtain the stack version using the SHCI_GetWirelessFwInfo function. Now, I am working with a SWBA (single core) but I was unable to find an equivalent function to ...

DIMMABLE COLOR LIGHT callbacks never invoked

Hi there and happy new year! I am currently trying to develop a dimmable color light with an stm32wb55 (Nucleo Board). Everything seems to work when connecting the device to a zigbee2mqtt server over zigbee. But actually all color server related call...

STM32WB5MMG module-based USB device ZigBee APS Coordinator with FreeRTOS

I'm working on a project based on the STM32WB5MMG module that must support the following three building blocks:ZigBee APS Coordinator - Only APS Layer packets, I dont need nor want the ZCL or any compatibility.USBFreeRTOSThe examples for the STM32WB5...

Active tampering event as a wakeup source in Standby mode

Hello, Can you please share an example code where active tampering is enabled in Standby mode and tamper event (disconnect loop) is used to wake up the MCU.I would like to know how we can configure the TAMP as a wakeup source during Standby. If you c...

Resolved! STM32WB55 freezing when returned from STOP2 after RTC wakeup

Hello,I modified the BLE Beacon example to send 5 beacon packets and then enter into the STOP2 mode. It is possible to wake-up and resend 5 packets when a button is activated. However, when the time is set, the MCU wakes-up, and freeze.The function U...
