Resolved! STM32WB55RGV6 – BLE stack stopped working after switching projects (even old examples fail)

Hello,I am working with an STM32WB55RGV6 on a custom board powered by battery (always connected).I successfully ran the Proximity example (non-RTOS) with BLE stack before, but after I worked on another project that used BLE stack + FreeRTOS, the BLE ...

STM32 Sleepy End-Devices loosing connection at random points in time

Hello, I am developing a Sleepy End-Device based on STM32WB5MMG which should read and transmit sensor data periodically. The board is mounted to a PCB with the recommended layout for optimal antenna gain. The sensor readings are transmitted with a cu...

Resolved! Cannot run any example on Nucleo-WB55RG board

Hello @STTwo-32,I was having the same issue and pressing the "start wireless stack" button did the trick for me. I was assuming after flashing the FUS & BLE Stack firmware, is that the CPU2 would be up and running already. So, does this mean that we ...

STM32WB5MMG Ble connection problem

Hello!I have an STM32WB5MMG with a breakout board (more specifically Sparkfun ATP breakoutSparkFun MicroMod ATP Carrier Board - DEV-16885 - SparkFun Electronicswith the STM32WB5MMG module SparkFun MicroMod STM32WB5MMG Processor - DEV-21438 - SparkFun...

Resolved! NUCLEO-WL55JC stop mode consumption

Hi everyone , I'm testing ultra-low power on the NUCLEO-WL55JC using STM32CubeIDE . My goal is to reach ~0.9 µA in Stop 2 mode, but I consistently measure around 2.9 mA, even with the debugger disconnected. My setup: Stop 2 mode enabled MSI @ 100 kHz...

Resolved! Clock settings are reset when loading IOC file

Hello,I am having an issue with my STM32WBA65MI-based project file (IOC file) and CubeMX (6.15.0). It also happens when configuring the IOC file in CubeIDE 1.19.0.When I configure the clocks and then generate code and save the IOC file and then close...

Is RTC needed on STM32WLE5Cx

Greetings,This is my frist time with wireless mcu. I just want to ask whether RTC is required for LORA Sub GHz Phy communication ? Any help will be greatful.

Resolved! STM32CubeIDE 1.19.1 + STM32CubeWL build fails on new project: 'ResponseTimeout' member not found

Hello,I'm having trouble building a LoRaWAN project targeting the STM32WLE5JCI6. The same error occurs even on a clean, newly created project, which leads me to believe there might be a compatibility issue between the IDE and the software package.■ T...

Resolved! B-WL5M-SUBG1 LoRa communication range issue

Hello everybody,For a proof of concept, I attempted to validate the LoRa modulation by having two B-WL5M-SUBG1 boards exchange ping-pong messages. However, I couldn't manage to exchange data with these boards at a distance greater than 230m in an ope...

Resolved! Can we power STM32WB0 from two external voltage sources?

We would like to power the VDD33 domain of an STM32WB0 device (STM32WB05KZ) from an external 3.3V source and the other domains from an external 1.8V source. In theory, it should be possible - by supplying 1.8V to VDDSD in SMPS BYPASS mode, or directl...
