Resolved! More SWDIO/SWCLK bugs for STM32WL33 generated code

I have found another bug in SWDIO code generation. I previously reported that no code is generated for SWCLK, but if both are relocated, SWDIO is also incorrect. The .Alternate uses a define of GPIO_AF1_SYS, which does not exist in stm32wl3x_hal_gpio...

Resolved! Timer TIM2 does not work when BLE is initialized in STM32WB55.

Hello.I am facing a problem: timer tim2 is not working with initialized ble and tasks and timers HW_TS (button and LED processing). Just in case, I checked that TIM16 is working, but it is busy with another task, so I can't use it. I've tried many th...

Resolved! STM32WL33CC1 – Wakeup LPAWUL/MRSUBG Failing After 10m

Hello everyone, I’m experiencing an issue with communication between two STM32WL33CC1 devices. I’m using one for LPAWUL wakeup receiver and the other for MRSUBG transmitter, but I noticed that beyond 10 meters, the communication starts failing....

Resolved! P-Nucleo WB55 USB Dongle Stack Programming Problem

I own 2 P-Nucleo-WB55 boards and dongles. I was able to program the FUS, Stack and FW in both Nucleo boards, but now I want to do the same with the dongles but I cannot program the FUS or the Stack in none of them. * In one of them I get:FUS status i...

Resolved! STM32WB55MMG Cannot Start FUS form running firmware to wirelessly update BLE stack

Respected Members,We are using STM32Cube Package 1.16.0 and STM32CubeIDE v1.12.1. We have 10,000 devices in market with BLE stack v1.16.0 and FUS v1.2.0 (STM32WB5MMG). We encountered a BLE related disconnection bug that was resolved when we switch to...

How to use Autonomous mode with STM32WBA55 (USART2 with GPDMA)?

Hello,I am using a STM32WBA55 controller and want to wake up from sleep mode (STOP1) as soon as an external interrupt (UART start bit) with falling edge occurs on pin PA11 (PA11 is also the USART2 Rx pin).Is there a possibility (e.g. with USART auton...

Resolved! Development board for STM32WL5MOC

Hi, I am planning to use STM32WL5MOCH6TR which you have suggested. So, to start with can I use this expansion board which contains the same chip for prototype purpose. Can I order this board https://www.st.com/en/evaluation-tools/b-wl5m-subg1.html?ec...

Stlink-V3PWR occurs embed Debug Authentication

Stlink-V3PWR no longer works because it displays the message "embeds Debug Authentication, please perform a discovery using Debug Authentication" and "Connection to target must be established before performing file download operation". I have already...

MRSUBG/LPAWUR Communication WakeUp

Hello Is it possible to communicate with the LPAWUL using only the STM32CubeMX MRSUBG/LPAWUR settings, to wakeup sending a direct message through the data buffer? I noticed on GitHub that the CRC calculation and the concatenation of the preamble and ...

Resolved! STM32CubeIDE not generating correct code for SWCLK on STM32WL33

In my design I needed to use the SPI on the 32-pin WL33, which normally is SWCLK, so I relocated it from its usual PA3, to PB2. When connecting the debugger, it was unable to find the target, which is usually an indication of incorrect connections to...
