Hi Nikos,

It is the new config for nRF53. It erases all user-available non-volatile memory and disables the readback protection mechanism if enabled. You can type "nrfjporg --help", and it will list the usage.

[quote userid="77782" url="~/f/nordic-q-a/64848/how-to-connect-to-nrf5340-from-smart-phone/264850"]Are you able to run the following commands with nRF-Command-Line-Tools/Download?[/quote]

What are those commands doing? I couldn't find the --coprocessor, CP_NETWORK and CP_APPLICATION on nrfjprog commands documentation.. Is there any additional documentation?

You're using the programmer (from nRF Connect for Desktop) to flash your board isn't it? Did you try the "Erase all" and then the "Read" to verify that the memory is empty?

Did you try an example that do not require softdevice?

Also check this post

I recommend you to follow the Running a first test and Programming an application of Getting started with nRF Connect SDK (nRF53 Series)

Download the latest SDK.

www.nordicsemi.com/.../Download

Then navigate to examples -> ble_peripherals -> blinky example

infocenter.nordicsemi.com/.../ble_sdk_app_blinky.html

RE: how to connect to nRF5340 from smart phone?

woff — Sat, 15 Aug 2020 09:52:55 GMT

Where is bliky example.

Please give me URL.

Thank you.

Hi woff,

Install nRF connect from app store. Then flash your nRF5340 using one of the ble peripherals example provided by Nordic's SDK (I suggest you starting with the bliky example). After flashing your board it will start adverising it self for a period specified on the example. During the advertising period you will be able to scan your device using your phone as central. Open the nRF Connect app and you will normally see your nRF5340 advertising.

Hope that helps.
