    <title>NFCのトピックNT3H2111 from RF Detect (Phone)</title>
    <link>https://community.nxp.com/t5/NFC/NT3H2111-from-RF-Detect-Phone/m-p/1037872#M6930</link>
    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Currently, I use this IC for testing. And on this stage, I can use micro-control through I2C to read/write NT3H2111 in user memory (1 K version), so I implement a function to write NDEF message into user memory, then I use Android phone and turn on NFC and launched "NFC TagInfo by NXP" Application, but the phone cannot detect anything.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So, I want to know 2 questions as following,&lt;/P&gt;&lt;P&gt;1. Does any configuration I need to be set through I2C first?&lt;/P&gt;&lt;P&gt;2. I think even NFC tag has no content, the phone still need to detect the NFC tag, isn't it?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;ps. I use same phone to detect other NFC tag product, the phone can detect it, so I think that there has no worry from phone side.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thank you so much.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Griffith,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Could the tag be detected before you write the NDEF data into this device via I2C? Please kindly clarify.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for your patience!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Have a great day,&lt;BR /&gt;Kan&lt;/P&gt;&lt;P style="min-height: 8pt; padding: 0px;"&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;-------------------------------------------------------------------------------&lt;BR /&gt;Note:&lt;BR /&gt;- If this post answers your question, please click the "Mark Correct" button.
