Hi.

This question should be asked on u-blox's forum.

[quote user=""]U-blox NINA-B111-04B is being adopted. (Nordic Semiconductor nRF52832 is used)[/quote]

If you only have the U-blox NINA-B111-04B chip and not the EVK-NINA-B1 evaluation kit,you have to use an external debugger to program it.

[quote user=""]Please tell me how to change the chip firmware to test firmware.[/quote]

If you take a look at the datasheet for U-blox NINA-B111-04B , you can read the following :-)

You can use SDK 15.3 and SoftDevice S132, download these here. Find a suiting firmware and flash it.

[quote user=""]Also, please tell me how to restore the firmware after rewriting it.[/quote]

I don't know what firmware u-blox uses, you have to ask on the u-blox forum.

Best regards,

Andreas
