Client board can't detect my new notification characteristic in the server

Hello! I am using stm32wb55 boards to exchange data. I added a new notification char in my server but client doesn't notice when I update the value of my new characteristic. But in ST BLE Sensor I can receive notifications from my new char, and also ...

– Integrated balun to reduce BOM

we are using ble in stm32wb series – Integrated balun design is there any reference schematic .the height of our application is 40feet can we use this ble with balun anteena or we will need an external antenna who we calculate the range and power ?

STM32WB - Problems with BLE and RTC

Hey Guys, Im new to ST and have the following Problem with the STM32WB55.I want to use the BLE function while the RTC is running in the background. The BLE should run for 10 seconds and shutdown after for 1 minute.When I go into the Standby Mode (Wit...

STM32WB55 BLE Beacon Example doesn't work

Hi all,i bought the STM32WB55 Nucleo Pack and I tried different examples from the STM32WB55 Firmware Package. The BLE Datathroughput example worked fine for me, but the BLE Beacon won't work.I updated the FUS to the newest version.I flashed the newes...

Resolved! How do I connect the ground of a high-speed external crystal oscillator in the STM32WB55?

I've looked at the reference design in the application note AN5615 page 13. This micro controller has integrated load capacitors for the high speed external oscillator. In the bottom right package, on the 32Mhz oscillator there is a symbol leading to...

Updating Network Stack through SWD on STM32WB55 Leads to Errors

I attempted to update the network stack through SWD on a few STM32WB55 nucleo boards, dongles, and custom PCBs. The results were similar in all cases. When attempting to query the processor to see if the FUS is out-of-date (it should be since these w...

Bootloader STM_OTA update firmware and access to BLE characteristics via BLE and python script or other CLI

Hi all,I using Nucleo STM32WB55 and bootloader from STM (STM_OTA). For update firmware I using for now STM32CubeMonitor-RF and stm32WB USB DONGLE (which is part of nucleo kit). Now I would like to do this in other way - other tools, CLI, scripts...Is...

Resolved! HSEM HAL strange behavior

Hi,I'm playing around HSEM module and i noticed strange behavior. Why calling:HAL_HSEM_FastTake(HSEM_ID_0);orHAL_HSEM_Take(HSEM_ID_0, 0);lock all semaphores at once instead of just locking single semaphore specified by a macro using 0 as processid?Th...

BUG report: Code generation on STM32CubeIDE for STM32WB with RTC in LL

Hello,when specifying "use low level driver" for RTC in "Project Manager->Advanced Settings" of ioc editor in STM32CubeIDE, the generated code of the STM32_WPAN does not compile anymore, since it needs the drivers in "HAL version". It must also compi...
