can you also add where in the documentation if mentions to include cert.pem?

Please note that Cortex only supports the WebSocket Secure (wss) protocol. It doesn't support the plain WebSocket (ws) protocol without encryption.
The Cortex web socket server uses a self-signed certificate. When you install Emotiv softwares, the installer has already installed the Emotiv Root CA file and ask the system to trust it, so most of the time, your application don't need to configure anything else.

why are we passing in a cert.pem file if it's saying that it doesn't need it? Do you have reference to where you got this code from? Have you tried running this code without the cert.pem file and without the SSLContext?

i think that means the launcher itself because the section after that is talking about using a raspberry pi as the wss server. it wasn't working without the cert.pem file

nit: but in the documentation they say to call getUserLogin to check if the user already logged in.
https://emotiv.gitbook.io/cortex-api/authentication
First, you should call [getUserLogin](https://emotiv.gitbook.io/cortex-api/authentication/getuserlogin) to check if the user has already logged in though [EMOTIV Launcher](https://emotiv.gitbook.io/emotiv-launcher/). Then, you must call [requestAccess](https://emotiv.gitbook.io/cortex-api/authentication/requestaccess) to ask the user to approve your application.

how does the value of session_id change? Will it be different every time?

yeah, after the script stops running the session is closed so a new session id needs to be generated on the next run
A session is linked to an application. All the sessions of an application are automatically closed when the application is disconnected from the Cortex service. A session is also closed if the headset is disconnected.

why do we call this twice?

whoops, that was remenants from testing, i don't think it ever reached the call on line 421 when i was testing it but hopefully that's just because i was exiting the experiment early/no actual hardware

what is warning 18?
There was a problem hiding this comment.
it's for successfully saved record
You must stop the record before you can export it. If you want to export a record immediately after you stop it then you must wait for the warning 18 before you try to export.

gotcha. Maybe link to the documentation and copy paste this:
The record data has been successfully saved. Cortex sends this warning when a record is done with some long-run post processing after record is stopped.
