Why connection loss during send command to STM32WB55 MCU on STM32CubeMonitor-RF GUI?
I have a self-design STM32WB board and properly flash "stm32wb5x_FUS_fw.bin", "stm32wb5x_BLE_Stack_full_fw.bin" and "BLE_TransparentMode_reference.hex" STM32_Programmer_CLI.exe. Now I am trying to use STM32CubeMonitor-RF. When I try to connect to it ...
Where can i find the user manual for the ST Bluetooth LE Mesh Library?
The Mesh Library file ist in STM32CubeWB\Middlewares\ST\STM32_WPAN\ble\mesh\Library.And the user API is in ble_mesh.h.When i want to use it how it is described in ble_mesh.h there are many undefined references, so i have to implement many functions, ...

LoRaWAN Fragmented Data Block Transport package. How to make it work ?
Hi everyone!I am trying to make the LoRaWAN Fragmented Data Blok Transport package work. As a first step, my goal is to send a file such as a txt document (or whatever) to my end-device.I work with a STM32WL and an End_Node project. I have already ad...
current measurement (ADC) when pwm is ON.
Hi,I have stm32wle5 and a circuit to measure current. stm32 will generate a PWM using timer1 ch1. The opamp's output is also connected to the ADC input of stm32. I want to measure the current (read ADC values) when PWM is on. Preferably in the middle...
Resolved! LPTIM1 one-shot mode does not work
I am using the LPTIM1 to aquire a sensor measurement trough interruption each T period. When I set it in continous mode (reference manual says: To enable the continuous counting, the CNTSTRT bit must be set) everything works out well. HAL_LPTIM_TimeO...

STM32WB15CC Custom Board Target No Device Found
Hi.I'm having hard time with my custom board based on STM32WB15CC.I referred Nucleo-WB15 schematics but using ST-Link V2 instead of ST-Link on Nucleo Board.I had an experience of STM32F411 so I thought this time I also can do it by STM32WB15. However...
STM32WB55 - How to use RTC under backup battery.
I work around a project based on STM32WB55.In this project it is necessary to keep a clock / calendar when the card is off.We usually use external real time clock / calendar such as PCF85063A.I work with the core board and try to use the WB55 RTC, wi...
UART reading problem
Hello,I have STM32WLE5CBU6 and I communicate with my Quectel chip over standard UART communication (interface LPUART, PA2, PA3) via AT commands. Transmitting from STM to Quectel is always working well, but when I want to read response from Quectel ch...
