Hi Jared,

Thanks for the update. I'm now on vacation for two week, so I will give the code a try when I return.

Many thanks for your support.

Hi,

Here is the whole record text sample from NCS v2.5.0 with precompiled hex for nRF52840 and nRF52833. I've tested that they work on the nRF52840 DK and the nRF52833 DK.

build: nRF52840

build_1: nRF52833

regards

Jared

Hi Jared

Do you think that's what the issue is then? My initial target (planned end product) will use a NRF52833. I have a DK for this device (BL653 from Laird - BL653 Development Kits - Ezurio | Mouser ). I couldn't get the NFC working on this either - so I then tried to get the NFC example working on the NRF52840 Dev kits I have....

Can you supply me with a working NFC sample hex code example and project based around the NRF52833 so I can validate it works with this the Larid BL653 hardware ?

Kind regards

Michael

Hi,

You're using a preview development kit. A PDK is an early version of a DK that contains an engineering version of the nRF52840 instead of a release version.

The PDKs are not supported in NCS,

Buy a Development Kit,

Hi Jared,

Please see my reply below - I'm still looking for a solution. I can't import the project zip contents as an application into Zephyr /VSCode as it says the folder does not contain an application

Hi Jared,

Sorry I haven't got back to you earlier as I have been busy on other urgent projects.

Unfortunately I am still having issues with this. I have downloaded the zip file and extracted the Zephyr.Hex file (117kb) from the Zephyr directory. I have flashed the hex code to Two of my NRf52 DK boards it using the NRF programmer utility.

Both boards seem to program okay (no reported errors).

When I use the Nordic NRF NFC tag tool on my phone, neither board is detected as a NFC tag device.

My phones NFC tag reader seems to be working as it still detect an old NFC hotel room key card (as shown in the picture).

I tried to open your project in Zephyr to recompile/debug the code but it says that the project does not contain an application source:

Any ideas as where I could be going wrong? Is there a hardware switch on the NRF52 DK, or if it just a case of plugging in the NFC antenna?

Kind regards

Michael

Hi,

Yes that is the Zephyr based SDK, namely nRF Connect SDK.

I used the v2.5.0.

Here is the build folder with hex file:

devzone.nordicsemi.com/.../2475.build.7z

I've tested with the Google Pixel 7 Pro and with a Samsung phone as well.

Hi Jared, is that the SDK in Zephyr (which is the SDK I am using)?

Can you share the generated hex file output so that I can try it to test my hardware.

Also is it possible to share the Zephyr project (in it's entirety so I avoid any import issues (as when I bring the record_test sample into Zephyr mine doesn't work).

What phone app are you using to scan the tag?

Cheers

Michael

Hi Michael,

Yes, nRF Connect SDK v2.5.0, tested with both nRF52840 and nRF52832 DKs, sample is record_text sample,

Hi Jared,

Yes I have two Nordic NRF52840 DK kit (unmodified) and three NFC trace antennas. My phone has NFC enabled and I can read an NFC TAG (an old room hotel key).

Are you using Zephyr as the development environment - which example are you running?

Kind regards

Michael

Hi there,

I just tested the sample with my nRF52 DK on NCS v2.5.0 and it worked for me.

Have you done any modifications to the sample? Have you made sure that NFC is turned ON, on your phone?

regards

Jared
