tca9548a not responding
I have a STM32WB55 board where I have two I2C connections:1. LSM6DSO IMU2. TCA9548A with downstream I2C to hall sensors The TCA9548A I2C multiplexer does not ACK when addressed. The firmware scans 0x70 (this should be correct already)–0x77 and gets n...

Change LPUART clock from LSE to HSI after wake up from STOP2
Hi, I'm using an STM32WL5MOC where the LPUART is used to wake up the module from Stop2 mode. Since I have a lot of data to transfer, I would like to ask how I can switch to the HSI clock after waking up, and then, of course, switch back to the LSE to...
STM32WB5MMGHx FreeRTOS and Custom BLE p2p_server app
Hello.I'm currently working on the above cpu and trying to implement a custom ble p2p server app. I have 1 service and 2-3 characteristics and i want to add Freertos for time critical constraints managenments. Correct me if im wrong, but it seems tha...
Resolved! [Solved] STM32_Programmer_CLI returns incorrect BLE Stack Version after programming
Issue Description:I am using the `STM32_Programmer_CLI` to flash the BLE Wireless Stack on an STM32WB series MCU. However, after the programming process is complete, the memory read returns an unexpected value at the Stack Version address, even thoug...
Resolved! Using STM32WB55: FreeRTOS osThreadFlagsWait can return osErrorTimeout early
I have come across an issue which I believe is a bug in the implementation of the osThreadFlagsWait function. Scenario A thread is waiting on a flag (e.g. 0x2u) for a timeout above 0, before this timeout should occur, there are multiple other flags s...
Backup registry save and system reset risky for STM32WBA?
Hello everyone, as mentioned in the title, I'm using STM32WBA in a project. Immediately after sending data to the stm32wba coordinator, I add an expression to the backup register and reset the processor using `Nvic_system_reset`. I check this at s...
Resolved! Expansion Board with Quad SPI NOR FLASH
Are there any expansion boards with Quad SPI NOR Flash chips? I am interested in using it with a NUCLEO-WB55RG board.Preferably it should use the Macronix 25L6433FM2I-08G chip, but that is not a hard requirement. This chip is found on the X-NUCLEO-GF...
How to design STM32WL55 with IPD for 865MHz
Is there any way to optimize the IPD BALFHB-WL-01D3 to work at 865MHz at 22dbm for STM32WL55? And is there any hardware design guide for power of STM32WL like it is there Hardware design guide for STM32L0 application note AN4467.
BLE: intermittent connect, repeated disconnect reason 0x3E during connection attempts
Hi ST Community,I’m working with STM32WBA (STM32WPAN / BlueNRG-style stack APIs). I’m using Extended Advertising on the peripheral (connectable + scannable, secondary PHY = Coded) and a STM32WBA central that scans and then calls aci_gap_create_conne...
