STM CubeMX for STM32WB55 Nucleo board (must recent), is there reason why sequencer in utilities is not allowed to be selected for non-wireless project?. I would like to experimentr that for other roles and purpose.

STM32WB55CCU6 low energy Bluetooth microcontroller without USART interface

I am using the STM32WB55CCU6 low energy Bluetooth microcontroller. As I am not using the USART interface and don't need to support a Real Time Calendar clock, I didn't attach an external low frequency crystal resonator. However, I am wondering whethe...

Resolved! SYSCLK vs SystemCoreClock

Hello,I want to know difference between SYSCLK and SystemCoreClok.When ı try to configure clock of different peripherals I saw terms SYSCLK and SystemCoreClock. I use MSI for SYSCLK which is configured to 32MHZ and for cpu1 ı divided sysclk by 4 and ...

Resolved! STM32WB55 enable IPCC chage clock and broken usb

I'm generating code with STM32CubeIde 1.11.0 for a STM32WB55, in my test project there is an USB CDC and BLE is enabled.When I enable BLE also IPCC must be enabled, but after HW_IPCC_Init is called usb clock is wrong so my usb device doesn't work any...

Resolved! I have some trouble with my st32cubeMX. I can not enable the EXTI on line 2, why ??

The enable boxed are there, but only for EXTI line 2, it's greyed out.

hi team, i have one question can i use external j-link debugger for remove RDP and write protection and also flash the code into the controller(STM32WLE5JC) LORA-E5 board. and also please provide j-link debugger software to remove protection.

hi team, i have one doubt. what is the use of arduino extension connectors in stm32wle5jc controllers. and what is morpho extension headers and what you mean direct access to all MCU I/O's can you explain clearly what that means.

Resolved! Setting MSI,HSI or HSE and configure clock speed of SYSCLK ,HCLK and other cloks.

Hello, I have a stm32wb55 nucleo board,I want to know that whats is the logic behind that , In reference manual it says After a system reset, the MSI oscillator, at 4 MHz, is selected .Lets say I want to use HSI or HSE for specific application and I ...

Resolved! STM32WB55 IrDA hardware setup

after looking over all the documentation i could find (datasheet, reference manual, etc.), i could not clearly find how i am meant to connect IR LED(s) for IrDA communication with an STM32WB55. The image i attached is a screenshot from the reference ...

Resolved! STM32WB BLE OTA low upload speed on some phones

Hello,I am using BLE_OTA project for STM32WB55. I upload a bin file which is 350 kb using ST BLE Sensor. However, the upload speed is so lower for some phones. For example, it takes up to 450 seconds on some android phones while the others take 25 se...
