WPA2 EAP TLS: Increasing speed to connect

[nubiator]

Hi there,

I am currently working on a project with the ESP32 (IDF 3.1.4) and WPA2 Enterprise network.

In my scenario I am using 4096 bit certificates. The ESP32 connects to the AP, sends a message via http and goes to deepsleep.

The certification process however takes up to two seconds. Is there a way to speed up the process?

It seems that the ESP is sending the certificate in chunks of 1000 bytes. Can I increase the size to speed up the process?

Question:
- Is there a way to speed up the WPA2 EAP TLS certification process (I am currently using the WPA2 Example)
- The Wifi Events seem to be a bit strange. Can I speed up something here? (After connecting to wifi i disconnect to AP)

Many thanks.

Best Regards

Sometimes I also see this (unable to connect to the AP) > Restarting the client helps:
