Which BLE stack firmware version is compatible to this library for STM32WB55?

[tankist-git-2]

I've got WeAct Studio STM32WB55 board. I'm using Arduino IDE 2.3.6. In Arduino IDE the latest library version is 1.4.0. I try to build any BLE application from the STM32duinoBLE library and nothing works - every application is hanging on BLE.begin(). I've tried several BLE stack firmwares with the same results. Could you tell me which BLE firmware stack for STM32WB55 is absolutely compatible with this library?

Hi @tankist-git-2
Latest library verion is 1.4.1 and not 1.4.0: https://github.com/stm32duino/STM32duinoBLE/releases/tag/1.4.1

You should have a warning message to tell that your board was never tested with the library.
https://github.com/stm32duino/STM32duinoBLE/blob/32dd72a9719e6b289be1f7a3c319546e5a42c03f/src/utility/HCISharedMemTransport.cpp#L26-L29

As stated in the README:

In order to use this library with SM32WBxx series, you need to update the STM32WB Copro Wireless Binaries with stm32wbxx_BLE_HCILayer_fw.bin depending of your mcu:
https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/STM32WB_Copro_Wireless_Binaries

Each subdirectories contains binaries and Release_Notes.html which explain how to update it.

The version integrated in the 1.4.1 is defined here:
https://github.com/stm32duino/STM32duinoBLE/blob/main/src/utility/STM32_WPAN/README.md

So you have to use firmware from:
https://github.com/STMicroelectronics/STM32CubeWB/tree/v1.24.0/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x

Ok, I see. There was an issue with Arduino library update.

You should have a warning message to tell that your board was never tested with the library.

My board isn't Nucleo but WeActStudio STM32WB55CoreBoard WeActStudio STM32WB55CoreBoard wiki. It's ok if this board hasn't been tested before, I'm doing it now. I just need some assistance in some not obvious situations.

The version integrated in the 1.4.1 is defined here:

Are you serious? How should I find this file ever? Information like that should be posted on the main page with the capital letters! (seriously, I suggest you to do this).

Thank you very much for the assistance. I'm going to keep you informed about testing my board.

Feel free to provide a PR to enhance documentation. It is a community project and please avoid '!' it could be misinterpreted.
About your board hard to help without any information. Just pay attention to use HSE as a clock source.
