Resolved! No BLE for STM32Wb5x Zigbee_BLE_Dynamic mode

Hello,I try to test the BLE on my Nucleo-STM32WB55 board.I use the v1.21.0 ST package for WB boards with BLE_Zigbee_Dyn exemple.I can use Zigbee without problems, but i never be able to use BLE. I can't discover device on ST BLE sensor classic.I uplo...

Which STM32 for me?

I am looking for a board, and think that I need someone to say that they have used it, rather than googling for it. In the immortal words of Jimi "are you experienced?" I would like to program in Ada, so the STM32 looks ideal.If at all possible, I wo...
