The subscribed message from MQTT Server displays on MQTTool on smartphone.
Meanwhile, the Blue Led on EK-RA6M4 turns on and off by turns when button is pressed.
If you want to observe AT Command, use a UART to USB bridge and connect RXD of UART part to P410 pin on EK-
RA6M4 board, open serial tool such as Tera Term, and set the baud rate to 115200. Then AT command will pop up. It’s
an auxiliary way to debug the program and of course as an option.
Summarize: All described above is a simplest demo for a beginner. If you want a more complex example, please refer
to other samples.
