Establishing the initial connection with NUCLEO-WB05KZ, 7CC, and 9KE boards

[STTwo-32]

Users experiencing connection issues with the NUCLEO-WB05KZ, NUCLEO-WB07CC, and NUCLEO-WB09KE boards should check if the problem is due to the low-power mode. The low-power mode is activated by the BLE_p2pserver demo, which is pre-programmed on the boards out of the box.

The low-power mode enhances low-power performance but also turns off the SWD lines, making it impossible for tools to connect to the device. To resolve this, users need to enter bootloader mode.

For the NUCLEO-WB07CC and NUCLEO-WB09KE, this requires connecting pins 2 and 1 on the JP1 jumper of the MB2119-WB07-A02 or MB2032-WB09-B02 MCU RF board. 

For the NUCLEO-WB05KZ, users should connect pin 5 and pin 7 on the JP3 jumper found on CN3 of the MB1801 mezzanine board. The JP1 is not fitted on the MB2032-WB05-B03.

By following these instructions, users can restore connectivity and reprogram their Nucleo boards effectively.

Hi, I'm using NUCLEO-WB05KZ, read the user manual, I'm following the instructions in paragraph 7.12
But I can't cause the target to return to the boot section.

What shall be the exact jumper configuration on the MB1801 Board, and in the MB2032B target 
(note that JP1 in MB2032 is assembled).

What shall be the exact STlink configuration on the programmer?

And what shall be the procedure to return to the Bootloader?

Thanks in advance for your support.
