我正与短消息连接。 我的 GSM 调制解调器支持 PDU 模式 。 当我在05年使用 IEI 使用特定端口时, 我的 UDH 运行良好, 但后来我尝试使用 IEI 00 来连接。 我接收了两条信息, 合并为单条信息, 没有问题, 但我接收了无法读取的怪异字符。 下面是第一部分的 PDU 。

0041000B89062972624F6000A600000A005000AA10201547414AFAA7C76B9058FEBBBB41E6371EA4AEEEEB71757E173E983E8E832881DDD6741E4F4F7905A2A2AC0783D3D5E83C4C4F2F2F7DD0D0D032BFF12075BD0DD983DEF6B21C4447979741ECB03E22FFFC2E2E1055D06C5EBEB9F11F11A2496BFEF6E90F98D079EB6E814B97E5203ABA0C6C687F7910F9781AE838585EF8F820B1F720BFC77783CC6FFFFFFFFFFF6FE

这是为第二部分:

谢谢你提前帮了大忙

问题回答

你还记得给你的UDH加了更多的比特吗? 让你的UDS 开始在Septet边界上跳动吗?

例如,如果在您的 UDH (最常见的) 中您有 6 octets, 等于 48 位元, 那么您必须再添加 1 位元, 使 GSM-7 编码的字符从 septet 边界开始( 49 位元是 7 个 sepets) 。
