Application: This example uses M480 UART to drive ESP8266 for MQTT client functionality.
BSP Version: M480 Series BSP CMSIS V3.04.000
Hardware: NuMaker-IoT-M487 v1.3
This example code uses M480 UART1 to drive the ESP8266 WiFi module, establishing the TCP/HTTP server capability. When the ESP8266 module is connected to the wireless access point, it establishes a connection with MQTT broker, and publishes the message of NuMaker-IoT-M487 SW2 (GPIO F11) and SW3 (GPIO G5) status.
