Re: ESP8266 SSL server breaks the connection after several seconds

Hi JunHao,

Thanks!! I'll modify espconn_mbedtls.c to have a try. :D
I'll post result here after done.

Regards

EDIT: The result is quite good. I changed to "0". Server will keep the connection all the time (at least quite long time for my trial). Thanks again.

Is ESP8266 SDK 2.1.0 affected by KRACK (WPA2 attack)?

Hello,

Is ESP8266 SDK 2.1.0 affected by KRACK (WPA2 attack)? The attack will change WPA2 encryption key to null. I cannot find any clues because of binary library.

Thanks.
