Is it possible to save the initial firmware that came along with the STM32 P-NUCLEO-WB55 board?

[KWah.1]

I am intending to flash MicroPython into this board, where I understand there is extensive support for this. I would like to investigate the possibility of using ST-Link Utility to save the initial firmware that came along with the board, so that I will be able to rollback in the event I realize that MicroPython will not be good for my use-case.

Hi Rami QUINTIN and KWah.1 ,

Have installed the micro python on the Nucleo WB.

Works good and easy on gpio and adc with machine, I2C, Pin and ADC imports.

Couldn't find an easy to use library for BLE though, ubluetooth is imported.

Is there one to be imported which is auto configured so words can be sent back and forth?

Kind of missing the ease of Arduino and esp32 which has lots of examples.

The task is

"read an I2C magnetic sensor which has 1 address pin then send the data to the nearby pc via BLE".

Thanks for the attention, hope you can help
