stm32wl55ccu6 - synchronization between m4 and m0

I started my project from scratch in CubeIde. So just select stm32wl55ccu6, choose all necessary peripherals and lorawan. Unfortunately, from scratch, this MCU can't choose only one core option(M4). To be able to use the Lorawan option, I need to IPC...

Receiving HCI_HARDWARE_ERROR_EVENT event_time_overrun, advertising never observed

My company is working on a product based on the STM32WB55, using the full BLE stack, currently v1.11.0. The error described below was also occurring on v1.10.1 previously.As far as the host application on CPU1 knows, the device is advertising success...

STMWB55: Flash write access during BLE connection

Hello,We are trying to write(erase) the flash during BLE connection.If we follow the STM32Cube_FW_WB_V1.4.0/Projects/P-NUCLEO-WB55.Nucleo/Examples/FLASH/FLASH_EraseProgramExample the BLE connection terminates immediately (timeout error code).Apparent...

What is the connection between RTCCLK and Sysclock?

I am using hw_timerserver and sequencer for BLE. I added additional tasks to the sequencer for my application. It appeared that my tasks are running much too frequently, so I looked into the clock configuration of the RTC and found that WUCLK was d...

STM32WB SRAM2A what is the size that can be used without interfering with BLE ?

I really need to use the SRAM2A that can hold data while in standby mode.But I have a hard time finding how much of the SRAM2A that I can use without meddling with BLE ? I found (STM32WB software architecture AN5289) and the mention about SBRSA But n...

STM32WB55 ScanRequest stucks in hci_cmd_resp_wait forever after couple of hours of test

Hi everyoneI have ported p2pClient project to a custom board and kept it running for hew hours.I`m using the STM32Cube_FW_WB_V1.7.0 ilbraries and and imported system workbench project.Eveyrthing seems to be working but after 4 hours board was not res...

STM32WB55，on our customer board, ble statck init failed, but the code work well in demo board.

In the function Ble_Hci_Gap_Gatt_Init(), it stopped at hci_cmd_resp_wait(HCI_TL_DEFAULT_TIMEOUT);And does not advertising any signal.what the problem may be with my board.Thanks.

STM32WB55 locking up when characteristic value is altered

Hello,I am developing a system using an STM32WB55 Nucleo, such that the STM32 receives data from a Windows application via BLE changing of characteristic value, the STM32 then sends this over uart to an external device which returns an acknowledgemen...

STM32WL55CCU6 - QFN missing VR_PA

Hello,I build my own end node based on STM32WL55CCU6 in the QFN package.During bring up I noticed missing VR_PAVDDPA is available on pin 25.Can someone help me to understand why is missing? I check also on the oscilloscope and is missing too. Nothing...

Resolved! STM32WBxx programming stack from bootloader always results in FUS_STATE_ERROR_IMG_CORRUPT error

I am implementing a bootloader that will support OTA installation of a new BLE stack if needed. I want to be able to command the FUS to install a new stack and I am utilizing the delete WS and FW upgrade SHCI commands to do this. I am always deleti...
