EC200问题咨询

物联网模组
1

您好，我手头有两块移远的模组：EC200S-CN、EC200U-CN。在测试HTTPS的时候遇到问题，求助。
1.EC200S-CN在测试AT+QHTTPREADFILE=“UFS:3.txt”,80这条指令的时候一直返回+CME ERROR: 705，然后使用AT+QFLDS也返回ERR，请问EC200S-CN这块模组没有分配储媒介的空间吗？
2.基于上述问题，我使用了EC200U-CN做了测试，AT+QHTTPREADFILE=“UFS:3.txt”,80这个是成功的，AT+QFLDS也是成功的，但是在使用AT+QFLST查询文件的时候，返回+CME ERROR: 405，期间有一次返回过文件信息，后来就一直是返回+CME ERROR: 405。

基于上述两个问题，请移远大佬帮忙解答一下是什么问题，以及对应的解决方案是什么，谢谢~

1、请提供一下你的AT指令流程，705错误码表示你没有发起get请求
2、请提供具体的报错AT指令流程，405错误码表示没有发现文件

Hi everyone,

I’m currently working with a Quectel EC200U-CN GSM module and using QNavigator to pass AT commands. I’ve successfully managed to set up the module and can send commands without any issues. However, I’m facing a problem where there are no notifications for incoming calls and messages.

Here’s a summary of my setup:

  • Module: Quectel EC200U-CN
  • Software: QNavigator
  • AT Commands:
    • AT+CPIN? returns +CPIN: READY
    • AT+CREG? returns +CREG: 0,1

Despite the module being registered on the network and the SIM card being ready, I don’t receive any indication or notification for incoming calls and messages. I’ve gone through the AT Command Manual but couldn’t pinpoint what might be causing this issue.

Here are the AT commands I have tried so far to enable notifications:

  1. AT+CNMI=2,1,0,0,0 (For enabling new message indications)
  2. AT+CLIP=1 (For enabling calling line identification)

Unfortunately, these commands haven’t resolved the issue.

Has anyone faced a similar problem or have any suggestions on what I might be missing? Any help or pointers would be greatly appreciated!

Thanks in advance!
