Quectel module Internal memory for user data?

Hi there,

I am working with the EC200U-CN module and am looking to download a firmware binary file of approximately 2MB via a GSM 4G network. I would like to store this file locally on the module before sending this to my controller.

Could you please confirm if the EC200U-CN module supports user data storage directly? If so, I would appreciate any guidance on how to store the firmware file within the module’s available storage.

If the module does not support direct user data storage, could you recommend any workarounds, such as external memory options.

Thank you for your assistance.

Hi there,

I would like to add some more inputs to my previous querie

I am currently working with the EC200U-CN module and using the Qcom tool to communicate with it (USB). Below is the sequence of AT commands I am using to download a 1.4 MB file:

  1. AT+QHTTPURL=66,60
  2. I send a downloadable URL for a 1.4 MB file.
  3. AT+QHTTPGET=60
  • Response: +QHTTPGET: 0,200,1457964 (indicating the file was successfully fetched).
  1. AT+QHTTPREADFILE="demo",60000
  • Response: +QHTTPREADFILE: 729 (memory allocation failed).

To troubleshoot, I listed the files in the internal memory using AT+QFLST, which returned:
+QFLST: “UFS:boot”,15004
+QFLST: “UFS:firm”,286000
+QFLST: “UFS:demo”,589824

From this, I observed that the module is only saving around 600 KB of the file. Each time I delete the "demo" file and retry the download, the same behavior is observed—only ~600 KB is saved.

According to the hardware design documentation, the EC200U-CN module has 64 Mb of internal storage, so I am unsure why it is unable to save the full 1.4 MB file.

Could you please advise if there is any configuration or limitation I might be overlooking?

Thank you for your assistance.

AT+QFLDS=“UFS” //Query the space information of UFS.
+QFLDS: A,B
A is freesize,you can use it for your file
If your files are larger than the free space, you need to subcontract the packets
