How can the big core receive the values sent by the small core via "mailbox"?

[Gitefu]

Hello,

I have tried to use mailbox_test.
It looks like the example program executes only the communication from the big core to the small core.
How can the big core receive the values sent by the small core?

The small core program was developed by Arduino.

Best,

Hi @carbonfix ,

I'm sorry I forgot to mention your account.
I would be glad if you would let me know about a way.

Hello @arturmodz,

Thank you for sharing the video.
I watched the video but I already tried the introduction used in the video.
Through the introduction, I cannot understand how can the small core send the values to the big core.
As I wrote, I use Arduino for developing the small core program.

Do you know any other solution using Arduino?

Best regards,
