No. 1575 Re: Re: Re: Re: Re: Re: Re: at+pssl 2018-03-06

Dear Marc,

Thank you for your information.

The response message from "at+pssl" command seems normal.
We suggest that you may follow the steps below to check if "at+pssl" command works or not:

Open ezManager, click [Search All] ==> Select your CSE-M53N device.
Click [Status] and see if the "SSL Status" is available or not (Refer to the attached photo).
If SSL is activated, you can find the SSL status in Status window, and if SSL is deactivated, you won'st find SSL information there.

Then, you may try inputting "at+pssl=1" or "at+pssl=0" and check the Status window to see if those AT commands work.

Please feel free to contact us if there is any problem.

Thank you very much.
Best Regards,
