ESP-LAUNCHER Development kit for ESP8266

Hi to all,
I purchased this dev kit ESP-LAUNCHER ESPRESSIF - Dev.kit: WiFi | A/D,I2C,IR,PWM,SDIO,SPI,UART,USB; ESP8266; 20dBm | TME - Electronic components with the famous ESP8266.
After configuring the wifi in the esp8266, when a wifi packet is sent, how can i read the packet? Should i check the Serial?
