kazz12211 0:e450010334e1 2 * Use ESP-8266 (called ESP-WROOM-02 in Japan) from LPC1114
kazz12211 0:e450010334e1 3 * LPC1114 has only 1 Hardware UART so this class uses SoftSerial to
kazz12211 0:e450010334e1 4 * communicate with ESP-8266.
kazz12211 0:e450010334e1 5 * I wrote like this class for Arduino then partially ported to mbed.
