Description

when i upload my code i don't have error and the ESP start in auto connect AP but when i select a wifi network and put the password nothing happen and i get this in the serial monitor:
tail 8

I searched on internet And i found something about reset and cabling but i didn't understand the problem and i pretty sure my cabling is correct. I'm using Seeed ESP8266 With an arduino UNO and arduino IDE
