ESP-32 CSI and MIMO technology

[nodejs_advocate]

Hello everyone,

I have couple questions regarding using ESP-32 for CSI packets sensing.

1. Can I create a MIMO system by combining multiple ESP-32 modules with a single antenna? What are the important factors and challenges I should consider in setting up this configuration?

2. How can I synchronize the transmission and reception of ESP-32 modules to ensure they work together cohesively in a MIMO setup? What methods or techniques should I explore?

3. Is it possible to capture CSI packets using the ESP-32 modules? If not, are there any other recommended approaches or hardware options that would enable CSI measurement in a MIMO system?

I would greatly appreciate any insights, advice, or pointers to relevant documentation or resources related to this topic. Thank you in advance for your assistance!
