如何发送M24SR02 NDEF文件？

海兰


我们目前正在使用M24SR02-Y。使用''TOL_ScriptingTool_ACR122''软件和ACR122 NFC读写器设备，我们将一些数据存储到
''使用以下命令选择NDEF文件'：


; [1]选择NDEF文件

00 A4 04 00 07 D2 76 00 00 85 01 01 00（9000）

; [2] NDEF选择命令

00 A4 00 0C 02 00 01（9000）

; [3]将193字节数据写入位置0x00的nfc EEPROM

00 D6 00 00 C1 AA 01 38 26 06 00 03 0E F0 24 FD 45 14 00 D7 11 64 00 00 00 00 00 00 00 F0 24 00 00 00 00 A8 61 00 00 00 00 B5 0B 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00日00 00 00 00 00 00 00 00 00 3 3 00 00 00 00 00 00 00 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 3 3F 00 00 00 00 0A D7 23 3C 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 3 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00 00 00 80 3F 00 00 00 00（9000 ）


然而，NFC挂断并且不写入数据。数据为193字节，应该可以存储在一个命令中（最大值为246字节（数据表））。

当我们只发送56字节时它工作得很好但是57字节它已经停止工作了，为什么有56个字节的限制？

我们如何发送总共193字节？

NFC读写器有问题吗？
