I'm trying to fix a P-Nucleo-WB55 board using CubeProgrammer.However, the board shows a 0.0.0.0 version of FUS and Stack and I cannot start FUS.I don't know why there is no version because the FUS cannot be deleted forever in the FUS upgrade document...

I want to change the DMA memory according to the PWM signal and change the GPIO pin to turn on/off automatically based DMA memory information. Are there any good examples of this?

Thank you for your response.I look identified the issue in my code.One thing unclear is whether SPI communication starts automatically when I change the Tx memory when I activate SPI_DMA. My microcontroller code is currently sending received BLE data...

Could you send the link again? I'm trying to upgrade FUS following the "STM32WB Firmware Upgrade Service wiki" but there is no description when FUS does not exist.

You don't need even a dongle if you use the wireless module in your Laptop. I cannot share my software because of security but you can program the BLE connection program using Visual Studio and follow the below instructions.Below is an example of C# ...

We can access the dummy microcontroller using a very short jumper pin connecter.If we replace the jumper pin connecter to a normal 2.54 wire (length < 15 cm, resistance < 1 ohm), we cannot connect to the dummy microcontroller even. This problem has ...
