Hi ‘msfujino’,

Sorry for your trouble with the Python UI part. There is clearly an issue to write the data file, that I dont have on my environment. May be a restriction to write in the directory where you launch the exe. You could remove the part of the code that handle it in the Python code directly as its not a key feature by the way.

Regarding the flash, I didn’t have the info on the huge writes that the integrated Flash supports, thanks! I thought also that the size was 1 Mb, not 2. I could have done a simpler storage lib
Now, it’s done and it works as an ultra basic file system. -
In fact I struggle to get accurate information on the exact user space zone that is free. It looks very small according to my internet searches: xED000 to xF4000 (really?).
I have just put a comment on this subject in another thread: Accessing XIAO BLE Sense (nRF52840)'s onboard QSPI flash through non-mbed board - #3 by troubadour06
