使用AT命令从手机读取消息时出错 [英] Error in reading message from mobile using AT commands

问题描述

我的笔记本电脑连接了索尼爱立信k550i手机.我正在使用AT逗号与移动设备进行交互.

当我尝试使用AT命令AT + CMGF = 1将移动信息模式从PDU模式更改为文本模式时，它将返回错误消息+ CMS ERROR303.

我该如何解决这个问题?
请帮助我..............



是的，我正在尝试命令AT + CMGF =?.它返回(0,1).
当我给AT + CMGF = 0时，它返回OK.但是它只为AT + CMGF = 1返回错误.

推荐答案

修订(版本2):
信息响应"+ CMGF:(0,1)"表示您的电话同时支持PDU模式和文本模式.
它也应该在文本模式下工作.

尝试使用以下方法检查手机的功能级别:

Revised (Ver. 2):
The information response "+CMGF: (0,1)" indicates that your phone supports both PDU mode and text mode.
It should work in Text mode as well.

Try checking your phone''s functionality level using:

AT+CFUN=?

将其设置为1可获得全部功能
还要检查是否需要PIN码.
我不太确定这些限制是否会限制更改SMS模式，但请尝试一次，让我知道它是否可以解决问题.

-----
(Ver 1):
错误303表示不支持该操作.
请先尝试

Set it to 1 for full functionality
Also check if requires PIN.
I am not very sure if these restrict changing the SMS mode, but try it once and let me know if it solves the problem.

-----
(Ver 1):
Error 303 means, the operation is not supported.
Try this first

AT+CMGF=?

这将告诉您支持的模式.
如果ans为(0,1)，则两种模式均受支持.

我认为您的手机不支持文本模式，U必须使用PDU模式.

希望对您有帮助！

This will tell you supported modes.
If the ans is (0,1) both the modes are supported.

I think your phone does not support text mode, U will have to work with PDU mode.

Hope this helps!!
