AT + CUSD没有余额 [英] AT+CUSD doesn't get balance

问题描述

我有一个DataNet GSM调制解调器(华为移动宽带E173).我想与USSD代码* 141 * 1#取得平衡，但不幸的是我没有任何结果.

I have a DataNet GSM Modem (HUAWEI Mobile Broadband E173). I want to get balance with USSD code *141*1# but unfortunately I don't get any result.I get just OK in response.

我阅读了这些帖子以及许多其他文章: 通过USSD检查余额时出现错误 我尝试了IRA，GSM和UCS2，但没有结果. 如何通过USSD命令获得平衡? 我的端口选择正确，因为其他命令正常运行 AT命令-USSD 我最后测试了15个，没有这个

I read these posts and many others: Error on checking balance via USSD I have tried IRA and GSM and UCS2 but no result. how to get balance by USSD commands? My port is selected correctly because other commands work properly AT command - USSD I test with 15 at the end and without that

我的情况如下:

    AT+CSCS?
    +CSCS: "GSM"
    AT+CUSD=1,"*141*1#"
    ERROR
    AT+CUSD=1,"AA182DA68A8D1A",15
   OK

我应该能够取得平衡，但是我就可以了.

I should be able get balance in result but I just get OK.

推荐答案

我可以解决问题.我选择的端口错误.我的调制解调器有3个端口，分别是COM38，COM39和COM40.我曾经使用过COM38，但是当我使用COM40时，AT + CUSD = 1，"* 141 * 1#"可以工作.

I could solve the problem. The port I have selected was wrong. My modem had 3 port, COM38, COM39 and COM 40. I have used COM38 but when I used COM40 the AT+CUSD=1,"*141*1#" worked.
