1 Introduction

The DA16200 GUI tool lets users control the DA16200 EVK in a GUI environment. There are three modes of operation: Certification mode, Network mode and OTP mode (see Figure 1).
Figure 1: DA16200 EVK GUI

1.1 Certification Mode

This mode is for Wi-Fi RF test (Tx power, Rx sensitivity, etc.) also known as “TEST Mode”.

1.2 Network Mode

With Network mode, the Station or AP mode of the DA16200 is tested.
● AP mode: Soft-AP test with configurable parameters like SSID, security, DHCP Server, etc.
● Station mode: STA test to search and connect to an Access Point and check/test the STA
function
After the network mode is set, the user can test the TCP/UDP or the MQTT and manage the TLS certificates.
● Data Transfer: message exchange through the TCP Server/Client, and UDP session
● MQTT Client: message exchange through the MQTT protocol
● TLS Setting: management of TLS certificate that is set (e.g. Root CA, Client Certificate, Client
Private Key)

1.3 OTP Mode

This mode is for power calibration and temperature calibration with OTP memory location.

2 How to Connect

2.1 USB to Serial Driver

The DA16200 evaluation board supports USB to serial interface. The user connects to DA16200 EVK with the PC through a micro-USB cable and then two COM ports will be detected automatically.
One (UART0) is for console command and the other (UART1) is for AT command. Normally, the higher number COM port is for AT commands and the lower number COM port is for the console.
● Required the FT232 Driver installation for Windows ○ In most cases, it will be installed automatically
The FTDI driver for the FT2232 FTDI chip used on DA16200 EVK is available for download at the following link: http://www.ftdichip.com/Drivers/CDM/CDM21224_Setup.zip
● See the EVK User Guide [3] to find information about the UART1 port. AT GUI tool uses UART1
port.
● To update with a new DA16200 firmware, see the DA16200 EVK User Guide [3].

3 DA16200 SDK or Firmware Selection

There are a number of types of SDK and firmware for DA16200 such as Generic and Manufacture that can be found in DA16200 SDK/Image packages. Consider the kinds of tests you plan to determine which SDK or firmware should be picked up.
● Certification or OTP Mode: ○ SDK: DA16200_SDK_Manufacture_QFN_xxx.zip ○ Firmware: DA16200_IMG_Manufacture_QFN
● Network Mode: ○ SDK: DA16200_SDK_Generic_QFN xxx.zip
– The __SUPPORT_ATCMD__ where can be found in config_generic_sdk.h file should be
enabled.
[\src\customer\config_generic_sdk.h]
// AT-CMD features
#define __SUPPORT_ATCMD__ // Support AT-CMD
○ Firmware: ATCMD firmware should be picked such as
DA16200_IMG_Generic_QFN_ATCMD, DA16200_IMG_Generic_FcCSP_LP_ATCMD or DA16200_IMG_Generic_FcCSP_NP_ATCMD depending on SoC package type.
