Dear, customer:
Are you working in a company or a personal developer?

But I did not get access to the sources or documents.

Dear,customer:
We can release FTP account and Gitlab account to you via our Smart Management System.
You can download firmware and documents from FTP and git clone Android code from Gitlab.
But you need to fill sdk questionnaire table and sign NDA with Quectel.
By the way, do you have our EService account?
If yes, you can create a ticket in EService, then we can provide better support.
Thanks.

Hello
Thank you for reply.
No problem to fill out sdk questionnaire table and sign NDA.
Can you send me the Documents @ dca@hotmail.ch ?
I do not have an EService account. How to proceed to get one ?
Thank you !

Hi,
There are too many documents on FTP.
I think you can contact with local sales for your project.
Thanks.
