为什么M24LR套件中不能读出标签？

亲爱的Eckart，
iOS coreNFC不支持M24LR16E，因为它使用未在coreNFC中处理的协议扩展标志。对于标记类型5，iOS仅支持标记＆lt; = 4Kbits。
关于UM2274，你是对的：目前还不清楚。

我们会纠正并澄清这一点。
希望能帮助到你。

Dear Eckart,
M24LR16E is not supported  by iOS coreNFC , as it uses the protocol extension flag which is not handled in coreNFC. For tag type  5, iOS supports only tags <= 4Kbits.
Regarding UM2274, you're right : this is unclear.

We'll correct and clarify that.
Hope it helps.

你好，Eckart，
错字修复。 iOS仅支持标签＆lt; = 8Kbits !!!

嗨Eckart，
对不起我的误会......我以为是M24LR16。
我刚刚用两个M24LR再次尝试过
- 发现板，它与iPhone7一起使用。
 
请问您能分享M24LR发现的CC文件的值吗？你将需要一部带有ST25应用程序的Android手机。
通常，您的CC寄存器（4个字节@Address 0）应为'E1 40 40 05'。
我们已经看到，在生产中，M24LR发现没有很好地编程并且包含CC ='E1 40 FF 05'。所以，你试图在解压缩后立即阅读M24LR，它可以解释这个问题。
在这种情况下，我建议您使用ST25 Android应用程序正确地重新编程CC文件。
让我知道。
BR，
文森特

Hi Eckart,
sorry for my misunderstanding...I thought it was M24LR16.
I have just tried again with two M24LR
-discovery boards, and it works fine with iPhone7.

Please, could you share the values of CC File of your M24LR-discovery ? you will need an Android Phone with the ST25 Application.
Normally, your CC register (4 bytes @Address 0) should be 'E1 40 40 05'.

We have seen that, in production, the M24LR-discovery were not programmed well and contained CC = 'E1 40 FF 05'.  So, it you tried to read M24LR just after unpacking it , it could explain the issue.

In this case, I suggest you to reprogram correctly the CC file with the ST25 Android Application.

Let me know.

Br,

Vincent

嗨文森特，
这是错误。将CC寄存器设置为0x40后，我可以毫无问题地重置标签。
谢谢。
你知道iOS将来是否支持16 Kbit类型？
关心Eckart

Hi Vincent,
that was the error. After setting the CC register to 0x40 I can red out the Tag without problems.
Thank you.
Do you know if the 16 Kbit type will be supported by iOS in future?
Regards Eckart
