How do I place the STM32WB55 into Shutdown Mode with WKUP pins and RTC wakeup sources?

I am unable to successfully put the STM32WB55 into Shutdown mode and then wakeup via either one of the WKUP pins or the RTC. I can get the WKUP pins to work if I use HAL_PWRex_DisableInternalWakeupLine, but then it won't wakeup via the RTC. If I om...

Resolved! PCB Antenna for STM32WB shown in AN5129 Application note where used pcb stack-up with core 711.2 μm. Exactly the same antenna used in P-NUCLEO-WB55 (MB1355) where pcb thickness is ~1500 μm. How is it possible?

STM32WB BLE not Advertising

Hi,We designed a product using STM32WB series for BLE application. In our case we didn't follow any impedance for antenna due to size constraints. Now we are facing BLE advertising problem.Is the problem with impedance or any other. Kindly guide us ...

Resolved! Error when trying to terminate BLE connection

I'm using a WB55 Nucleo board and setting up a BLE connection with a 2nd WB55 Nucleo board using aci_gap_create_connection(). The connection succeeds and I am able to transfer data between the 2 boards. I would then like to terminate the connection. ...

I was reading the release notes for LoRa software expansion for STM32Cube and read that a bug had been fixed "Fix for issue of increasing power consumption over time" and "Update of AT_Master project to prevent FW from freezing after entering low power mo

Resolved! Bugs in CubeIDE code generation for STM32WB55CG (and others)

Hello,I have found some bugs in linker scripts generation when creating a project from CubeMX. Those bugs appears only when code is generated for STM32CubeIDE, related to linker scripts:/* Highest address of the user mode stack */ _estack = 0x2004000...

STM32WB55CG is under read/write protection in STM32CubeProgrammer_CLI and no protection in STM32CubeProgrammer.

In STM32CubeProgrammer I can set RDP on AA level and BB level, but in CLI mode read/write protection is constantly in BB. In CLI protection byte doesnt change, I mean I can't change itand can't write FUS or stack, and even check the fuse version.C:\P...

Can't program BLE stack to STM32WB55CC

I have successfully uploaded stm32wb5x_FUS_fw.bin to my STM32WB55CC and the next step resulted in the error I don't know how to deal with. Here is the CMD log ------------------------------------------------------------------ ...

Hi All, I'd like to use the new STM32WB instead of a BLE module and I would know if there is the RED certification of it, and if not how much are the cost to sustiain it. Stefano
