Power off the solution kit, insert DA16200 PMOD board into J25 (PMOD2 on EK), establishing the whole system just
as the picture at chapter 1.1.

Debug and download code to EK-RA6M4
The EK-RA6M4 features a SEGGER J-Link On-Board debugger, using Renesas S124 Debug MCU and SEGGER J-
Link® firmware to provide the on-board debug functionality, so all the customer needs for debugging is a Micro USB
cable.
Step 1. Insert Micro USB cable into Debug USB Micro-B connector (J10), establishing a debug channel.
Step 2. Modify the project according to the actual internet environment.
Import project into e2 studio, open project->src->da16200_AT.c, find the array variables associated with the internet
environment, such as the current country, ssid and password of Wi-Fi Router, IP address of MQTT Broker and ssid and
password for logging in.
