Flash NINA-B11X-BOOT3.0.1.zip is OK
Flash s132_nrf52_5.0.0_softdevice.bin is OK
Flash NINA-B11X-FW4.0.0-003.bin is OK
But It does not start. why?
It is in swdio version
Is not it necessary to have a file like?
Sorry, I've solved it myself.
When I finished writing NINA-B11X-Configuration-4.0.0.json, it became Ver4.0.0.
The correct procedure is different, but if you write 4 files in turn, it will succeed.
