RF430CL330H: general query

Hi,

Jaden Yue said:

1) Can our NFC interact with the NFC on the base in a point-to-point manner: transferring messages, data, and firmware?

Yes, you can transfer messages and data. Please note that the RF430CL330H sends data over the air based on what is loaded to the 3KB of SRAM memory of the device. Due to this, the maximum message size that can be sent in one connection is 3KB. To send or receive more, the NFC connection must be reset, and new data must be loaded into or read from the RF430CL330H. Please refer to the FAQ for additional information. https://www.ti.com/lit/sloa244

2) Do we need to switch the NFC working mode separately to support NFC card simulation and unlock the door?

I'm not clear with your question and your end application. RF430CL330H is a NFC transponder device supporting ISO/IEC 14443 Type B and NFC Forum Type 4B. You could pair RF430CL330H with a Bluetooth or Wifi device allowing you to perform custom actions such as unlocking a door. Please refer to the below whitepaper and app note.

3) NFC is connected with the Android main SOC chip. Do we have a demo code that can pass GMS?

No, we do not such example.
