Hello,

Could you please provide more information about what you are trying to do ? Which tag are you referring to ?

You can check in this link for the TapLinx which is one of the resources we provide for the customers so they can develop their NFC mobile applications, maybe that is what you are looking for.

Regards,

Hello Martinez,

Thank you for your prompt reply.

I'm an android developer and I'm trying to develop an app to connect this board,here is a picture of my board.

My board: QN9020+CLRC663(BLE+NFC)

The tag is the bottom left on the board.

Through my App, I can successfully scan and connect the board,but I can't read any information returned by the NFC.

Here is a picture of my BLETool.

But I can read/write successfully with the BLETool you provide,here is the picture

After BLE connection, do I need to send some instructions to receive the tag information read by NFC?

Or I need import a jar to use the API you provide?

Hello,

Sorry for the confusion.

If you are using your own board and it does work with the default source code with the NXP application the issue is most likely that your application is not receiving or interpreting in the correct way the information sent by Bluetooth LE you will need to check the format used to sent the information and translate it correctly to your needs in the mobile phone.

And  no, you do not need to use the APIs I mentioned in the first response as I thought you were trying to read a tag with your mobile phone and not seeing the information from the reader that is being sent to the phone through Bluetooth LE.

Hello,

Hope you get a solution.


You can try to use an sniffer to check/verify  the Bluetooth  communication and you can see how the packets are being sent.
