I have a STM32WB55 Nucleo with which I would like to implement a BLE client (mast, central). In the end it should be able to automatically parse with another BLE (slave, peripheral).
Currently I have no idea how to accomplish this task and my Google Skills were disappointing.
Does anyone have an example project or knows a good reference?

Hello @SGimm.1,
I recommend you referring to the "Academy -> eLearning Catalog", you will find there different official trainings, including the "STM32 Wireless BLE" under the "General Purpose Microcontrollers" topic.
You can also check the "Building wireless applications with STM32WB Series microcontrollers" AN5289 and you can have a look at the projects of the WB Cube Firmware, it will help you get started with your project.

Hello again @ChahinezC,
I implemented the BLE_p2p example and was able to connect two stm32WB55 boards with each other. I than tried to connect a sensor with a HC-08 BLE Modul to the Nucleo Client. I changed the uuid and name from the HC-08 (BLE v4.0) to the same uuid from the Nucleo server which was able to connect to the Nucleo client. Sadly the GAP between the HC-08 and the Nucleo doesn’t work.
Now my Question:
Is BLE 5.0 compatible with BLE 4.0? If so what kind of other configurations are there to enable the connection between the two? (UUID, Name, PIN should be implemented correctly)
Kind regards,
Samuel
