STM32WB05 reboots when starting to advertise

Hi I have an app working perfectly on a Nucleo board and the MB2032 for the STM32WB05. Just the standrd default setup there.I have built my own board now following the application notes and the guides. It all starts ok but as soon as it gets to the a...

STM32WB5MMG - custom PCB - BLE

Hi,I developed PCB with STM32WB5MMGH6TR. I have code which I used previously with STM32WB55RG (on Nucleo board). I adapted it for STM32WB5MMGH6TR and it works (GPIO, SPI, I2C) except the BLE part. So I took STM's BLE_HearRate example for STM32WB5MM-D...

Resolved! Delivery Date Changed from Jun-2026 to Feb-2027 – Request for Clarification

Dear STMicroelectronics Team,We would like to request clarification regarding the delivery schedule of our STM32WL5MOCH6TR orders.As indicated in the attached correspondence and supply reports, we were initially informed that our order would be deliv...

STM32WL3R high current consumtion in deep stop

Hello,On the STM32WL3R microcontroller, when deep stop mode is activated, the current consumption is about 1.3 mA, which is a very high value compared to the 0.8 µA specified in the datasheet. In contrast, when I activate shutdown mode in the same fi...

Resolved! STM32WB55 - Use LSI2 as a RTC clock source for waking up from STOP2 mode

Hi everybody, I have an application, where my device should go every record_interval into the stop2 mode. Then Wakes up then measure some sensor values, then goes into the sleep. Same goes over and over. The issue is, I am using the LSI2 as a clock s...

STM32WLE5CCU6 LoRaWAN Stack development

Hello everyone, I have my own custom board based on the STM32WLE5CC , and I want to build a LoRaWAN project on it. For the RF design, I used the MB1874-LP reference schematic as a base, together with the BALFHB-WL-06D3 balun/filter for a 2-layer PCB,...

STM32WBA Can't Initialize HSE

The problem I am facing is that I can't seem to get passed the SystemClock_Config() function call, more specifically, the HAL_RCC_OscConfig() function returns HAL_TIMEOUT in this part indicating that the HSE is not getting ready. /* Wait till...

Resolved! STM32WL33KCV TCXO

Dear Experts, I have an E04-400 module which contains a 48 MHz tcxo controlled through PB1 pin.If i set the module to use HSI it can work (blinks an LED, radio is off)If i set the module to use HSE (and set PB1 to 1 directly when main.c starts) the m...

Unable to upgrade FUS on STM32WB55 (WeAct) / FUS_NOT_RUNNING

I was trying to upgrade the FUS on my STM32WB55CGU6 (WeAct board) using an ST-Link V2, but it keeps spamming errors when I try to "Start FUS": Or when I try "Firmware delete":This is what appears when I read the FUS infos:These are my option bytes:I ...

[STM32WL3] RM0511 Rev 6: colored cells missing in register map tables

Hi, could you please check the colored cell highlighting in RM0511 Rev 6 register map tables? For example, page 304 states "The green cells indicates the register is in the VDD12o power domain" but no green cells are visible. This affects at least Ta...
