Hi there,

The trigger library is meant for the dongle, you can Build/compile with it in your program to do some DFU ,bootloader tricks.

exactly what you want, your python automation would handshake with the dongle to set DFU mode , Upload the new code and it would reset on completion, other options can make it stop and wait on reboot for a do over or boot the app.

HTH

Hi Robin,

If you have the same issue on native Window, then you might have the same issue discussed in the first half of this case: RE: custom nRF5340 board no bluetooth signal .

Could you please refer to the answer I link and see if that is the case?

Hieu

small precision : I use WSL1 (it seems that it is easier to manage USB connection with it than with WSL2)

And I tried executing my script directly on Windows and had the same result.

Try running Linux host somehow (e.g. via boot from USB stick). Windows and Linux have VERY different ideas about USB drivers, and mixing them will be a nightmare.

There is documentation that describes how to connect USB devices to WSL, but that stuff seems off topic here.
