GSM 调制解调器以 UCS2 格式发送消息错误 [英] GSM Modem Send Message in UCS2 format error

问题描述

我正在使用 Java 通过 AT 命令与 gsm 调制解调器(西门子)通信.
我将调制解调器的编码设置为UCS2".
发送电话号码后立即发送消息时，我从设备收到错误消息:

AT+CSCS=UCS2
好的

AT+CSMP=17,167,0,8
好的

AT+CMGF=1
好的

AT+CMGS="0919xxxxxxx"
错误

帮帮我，求求你了！:(

I'm using java to communicate with a gsm modem (Siemens) using AT commands.
I set the encoding of modem to "UCS2".
When sending messages as soon as I send the phone number I get ERROR from the device:

AT+CSCS=UCS2
OK

AT+CSMP=17,167,0,8
OK

AT+CMGF=1
OK

AT+CMGS="0919xxxxxxx"
ERROR

HELP ME, PLEEEEEEASE! :(

推荐答案

我认为您将 <da> 地址参数编码为 AT+CMGS 不正确.

I think you are encoding the <da> address argument to AT+CMGS incorrectly.

您指的是 91 和 92 样式，但您实际上指的是 在 UCS2 的 SIM 卡中编码 Alpha 字段 博客文章关于3GPP TS 11.11?

You refer to 91 and 92 style, but are you actually referring to the '81'/'82' format as explained in the Coding of Alpha fields in the SIM for UCS2 blog post about encoding as specified in 3GPP TS 11.11?

在您运行 AT+CSCS="UCS2" 后，每个字符串都必须以这种方式进行编码，因此例如从 UCS2 切换到 UTF-8 将是 AT+CSCS="005500540046002D0038".

After you run AT+CSCS="UCS2" every single string must be encoded that way, so for instance to switch from UCS2 to UTF-8 would be AT+CSCS="005500540046002D0038".

采用 80/81/82 编码的 Alpha 字段仅适用于某些情况，一般不适用于 UCS2 编码的字符串.特别注意上面AT+CSCS命令中字符串UTF-8"的编码与此无关.这也适用于 AT+CMGS 的 参数.

Alpha fields with 80/81/82 encoding only applies to some cases, and not UCS2 encoded strings in general. In particular notice that the encoding of the string "UTF-8" in the above AT+CSCS command has nothing to do with this. That also applies to the <da> argument to AT+CMGS.
