Thingy91: NFC sample reader

[Vincent MORENO]

Hello,

Do you know where I could find a sample to read NFC Tag with Thingy91 ? The best could be to have a sample sendind on MQTT NFC tags reads.

I read different posts and some said 2 years ago they were not working ?

Thanks.

Hello, really sorry to worry you but I buy the thingy91 to send by LTE-M scan reads by NFC and I'm quite blocked because I connot find examples to help starting. Thanks for your help.

Hi,

I think you might have missunder stood the capability's of the HW. The Thingy91 has a passive NFC tag, not a reader. 
See documetiaon: https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/hw_nfc.html?cp=14_0_2_3_0

Thanks for your response, I'm quite loss sorry.

The THINGY91 is done with a nRF52840 that can have listen mode we cannot use it for this ?

Thanks

Hi,

Maybe you can explain the Goal of your project, and i can see if i can guide you to the relevant info. 

In short, the Thingy91 is a prototype platform that has to micro controllers on it, one nrf52840, it does USB, BLE and NFC actions for the device. Then you have the nRF9160 it does the LTE and GPS on the device. 

The NFC that is on the Thingy91 is connected to the nRF52840 so any examples will be running on the nRF52840, it is a passive NFC tag, and not a reader, so if you want a NFC reader then you need external hardware and attach it to the Thingy91.

Hi,

Thanks for your comments and clear explanations. So for sure I need to connect a reader. In case of, do you have any documents or recommandations to attach a NFC Reader ? 

But I better understand now my fault reading too fast the thingy91 documentation :-(.

Thanks

Hi, 

Sorry for the slow response, but i dont have any specific third party NFC reader in mind that i can recombed. The Thingy91 does not have many GPIO accessible so there is a limit to how much you can connect to it.

We have hade similar questions here on Devzone before:
