RFテスト用firmware

[kugo]

U-blox NINA-B111-04B is being adopted. (Nordic Semiconductor nRF52832 is used)
For product evaluation, I would like to connect with Anritsu BLE tester MT8852B for evaluation. Please tell me how to change the chip firmware to test firmware.
Also, please tell me how to restore the firmware after rewriting it.
I'm not good at English, so please give me an easy-to-understand explanation.

U-blox社のNINA-B111-04Bの採用を進めております。（Nordic Semiconductor　nRF52832を使用している）
製品評価のために、アンリツ社製　BLEテスタ　MT8852Bと接続して評価をしたいと考えておりますが、chipのfirmwareをテスト用firmwareにする方法を教えてください。
また、firmware書き換え後、元に戻す方法についても教えてください。
英語が得意でないため、分かりやすい説明をお願いします。

Hi.

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

U-blox NINA-B111-04B is being adopted. (Nordic Semiconductor nRF52832 is used)

 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.

Please tell me how to change the chip firmware to test firmware.

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.

Also, please tell me how to restore the firmware after rewriting it.

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

Best regards,

Andreas
