Detailed Description
Esp8266 WiFi serial module.
Warnning: CH_PD pin has to connect VCC to boot from internal flash! Command has to end with "\r\n" If you can't get full AT output, set console same baudrate or higher, or set wifi baudrate low!!! DO NOT print console if you want get a long result from internet. Some bad data at beginning because the baudrate changed to 74880 : 0xd
: 0xa
