NRF52840 PCA10059 USB Dongle NFC

[Francis Dahl]

Hi to all:

First post and new to the Nordic universe.

I'm working on an example with the NRF52840 usb dongle using NFC.

I'm using the nfc_meshcop example and change it just to publish (I hope) some data through NFC. The ideia is that i can use my mobile phone to read from the NFC the data that the dongle is sending.

But I have no success on this.

So my questions are:

- Does the NRF52840 dongle has NFC or does it need an antenna to be connected?

- Can I make the NRF52840 behave just like a NFC card, not has a reader/writer, and if so, is the nfc_meshcop example a good starting point?

Thanks for the help!

Hi, and welcome to the Nordic universe (I like the ring of that )

 

nRF52840 dongle is nothing but a PCB hosting a nRF52840 SoC. The board itself does not have NFC, but the SoC does, you just need to attach a NFC antenna to P0.09 and P0.10 pins, tune it and program it as you otherwise would. You should note though that the dongle does not come with a NFC antenna, as oppsed to the nRF52840 DK, so as such it is a little more work to get up and running.

 

Best regards,

Hi Andreas:

Thanks for the answer.

That was what expected, the SOC is NFC capable, but since the dongle has no antenna, it doesn't work.

Any tips for an off the shelf NFC antenna that I can use?

Thanks again!
