Hi Abderrazek MESDOUA,

NXP NTAG I2C plus is a family of connected NFC tags that combine a passive NFC interface with a contact I²C interface. so it must work with a NFC reader to make RF interface available, so your scenario is no possible for this device.

Hi Chadi SALIBA,

do you also want to use this device in such kind of scenario? Please kindly clarify.


Have a great day,
Kan

Hello Mr Kan LI,

Yes, i have 2 FRDM k82f Kits and 2 NFC antenna Ntag I2c, and i want to exchange Data between them.

I chose this NFC device after i read in the Data sheet that i can write and read . Kindly find attached a screen shot of page 2 in the Data sheet of NT3H2111/NT3H2211.

If it is impossible to exchange data between the two kits using NT3H2111 of ntag i2c, do you have any suggestions on what can i use so i can make this data transfer between the kits.

Hi Chadi SALIBA,

Replace one NTAG I2C with a NFC reader IC should make this application possible. Alternatively you may use two NFC reader IC and make them in P2P mode.


Have a great day,

Hi Chadi SALIBA & Abderrazek MESDOUA,

If you prefer to NFC reader IC, I would recommend PN7120 or PN7150, there is also a FRDM-K64 demo available to work with either of them in P2P mode, you may download it from https://www.nxp.com/webapp/Download?colCode=SW3735&appType=license&Parent_nodeId=1464843492338729907... 

The demo is based on the latest ksdk 2.2, so it should be easy to port to FRDM-K82F. Please refer to the following for details.

* Support for all NCI based NXP's NFC Controller (e.g PN7120, PN7150)
 * Support FRDM-K64F NXP's Microcontoller Units
 * Based of KSDK 1.3, KSDK 2.0, 2.1 and 2.2
 * Demonstrates:
    o NFC Forum tags reading (read NDEF message)
    o P2P (NDEF message exchange through NFC Forum SNEP protocol)
    o Type 4 Tag Emulation
    o NFC Forum T2T and T4T tag writing (write NDEF message)
    o Raw tag (non-NDEF) access (MIFARE, ISO14443-4, ISO14443-3A and ISO15693)
    o Multiple tag support (up to 2 of the same technology or multi-protocol card)

Hello Mr Kan

I have bought the NXP NFC Controller PN7120 , but it's rather difficult to take in the hand. 

Because there is no demo for the k82, There is only one FRDM-K64 demonstration available, Which I can not to port to FRDM-K82F, Can you please tell me What are the main steps to follow to do it.

thank you.

Dear Kan,

Thank you for the link, i already have this demo examples, but what i
