SparkFun Thing Plus - NINA-B306 issue

I was able to get this sketch to work, then it quit

Red light on

First effort with SparkFun so I’m likely missing something simple.

Windows 11 computer

Error message:

Possible causes:

  • Selected Bootloader version does not match the one on Bluefruit device.
    Please upgrade the Bootloader or select correct version in Tools->Bootloader.
  • Baud rate must be 115200, Flow control must be off.
  • Target is not in DFU mode. Ground DFU pin and RESET and release both to enter DFU mode.

Thank you,

COM3 is apparently not the right port number for your Arduino . Check the Device Manager to see what it actually is.

See which COM ports appear when you plug it in and direct it to use that one

When I plug in the B306 II doesn’t assign it a port. I plug in a ScanDisk device and 11 assigns it as Mass Storage Device. I tried the cable that worked before and another cable.

I did neglect to say that 11 stop seeing the B306 after an update where 11 decided that iqvw64e.sys was a vulnerable driver.

Do I need a different driver?

Thank you,
John Woodyard

I think you probably just need to whitelist that driver again
