NFC USB Dongle - Displaying data during write

jollyto — Wed, 01 May 2024 19:09:28 GMT

Hello team,

I'm interested in learning if there's a method to retrieve the data sent to the NFC USB Dongle. Currently, I've successfully executed the 'C' example by enabling the #define CARDEMU_SUPPORT. I can both write to and read from the dongle. However, during the writing process, I'm looking for a way for the application to capture the data record sent by the writer. Any assistance on this matter would be highly appreciated.

The specific dongle I'm using can be found here: https://www.mikroe.com/nfc-usb-dongle

I am using the PN7150 NFC USB Dongle and attempting to communicate with my mobile phone. I ran the NXP-NCI_Windows_example.exe provided in example package SW4335. The application launches successfully, and the command prompt displays:

WAITING FOR DEVICE DISCOVERY When I bring my phone close to the dongle, it detects it successfully, and the following messages appear: LISTEN MODE: Activated from remote Reader --- NDEF Record sent Immediately after, the following message is displayed: READER DISCONNECTED

I initially suspected this might be a driver issue, but as per your documentation, no drivers are required. I’ve tested this behavior on multiple laptops and phones, but the issue persists.

Could you please help me understand why the reader disconnects after the NDEF record is sent? I’ve attached the logs from the command prompt for your reference
