How to testing Quecopen on EC21 module

I have an EC21 module. I heard from a Quectel engineer that I can use QuecOpen, but I’m not sure how to use it. Can I get a detailed explanation about this?

Thank you

Hi @wireless

First you need to get the QuecOpen SDK, I’m not sure if you already have it.
Then you need a development environment, such as ubuntu16.04, or 18.04. The code needs to be compiled here, and finally the USB driver for the corresponding environment needs to be installed, so that you can start your development.
The following video explains how to compile and run an application using the sdk, hope these can help you.

Thank you for your response.
I’m curious about how I can obtain the QuecOpen SDK.
