Update NFC NTAG data from BLE

[Vinay Krishnappa]

Hello,

I have a requirement to implement the following functionality. Can this be done?

Basically i need to store some customer info on the NFC NTAG. This has to customizable from an app. So, i want to be able to edit the reqd file on the app, pair the phone with the nordic device, push the data onto the BLE module on the nordic device which inturn should be pushed on to the NFC NTAG.

Post this activity when i read the NFC NTAG from say an NFC phone, this new data must be seen.

Thanks,

vinay

Hi,

I'm not too sure about the question, can you clarify what you meant? Do you want to write data to an external NFC tag? If yes, the answer is no. It’s not possible to write or read NFC tags using nRF52 NFC interface. External HW would be required for such use case (NFC Reader/Writer device)

Why don't you write new data to the NFC NTAG device directly from the phone?

Hello,

Thanks for the reply.

Actually, what you are suggesting is exactly what i want. Here is the flow that i am hoping to implement. 

1. Data is typed on the Android App (phone).

2. Phone is paired (BLE) with nRF52 and once connection is established data is passed onto the nordic device.

3. This same data is then written into the NFC NTAG. 

This new data must be readable from an external NFC Reader (like a Adafruit NFC reader/writer).

Hello,

I would like to add that the app will be sitting on NON NFC phones. Hence we cannot edit the NFC NTAG data directly from the phone and therefore the need to push the data from the phone to nRF52 over BLE and upon receiving this new data, nRF52 internally, must change the NFC NTAG data to reflect this new data. 

Hope i clarified the confusion.

Like I mentioned in the initial answer. If you are using an external NFC tag, it is not possible to write or read NFC tags using nRF52 NFC interface.
