How can I communicate with 2 raspberry pi I2C

I want to communicate with i2c between 2 raspberry picos. My code and explanations are in the images. But I can't see the other raspberry pico. How can I solve it?

Hello,

You are using both Pico's as master. One needs to be master the other one slave. The master controls the send/receive direction.

Replace your first code with something like shown in (to make it a slave and wait for send/receive commands from the master):
