Bluetooth Arduino/DWIN/DGUS

-----------------
UZA365SER 1.9 Overview
2025.12.23 DB Bug Resolved
-----------------
It is a very useful app as an operation test assistant in various electronic works because it has a wide variety of methods and functions for sending data to and receiving data from all devices that support the Bluetooth function, such as Arduino devices or DWIN serial monitor, using the smartphone Bluetooth function.

-----------------
[ Main Screen ]
-----------------
You will see a list of paired devices registered on your smartphone, so you can select a device and connect it with the [CONNECT] button.

-----------------
[ MENU ] - BPS Setting
-----------------
Before connecting to the device, you need to match the BPS and communication speed. The default is 9600BPS.

-----------------
[ MENU ] - Send & Receive
-----------------
It is a basic communication utility, no different from general communication apps. If there is data input, transmission, and reception, it is displayed in the reception box. Both transmission and reception can be sent and viewed in hexadecimal mode, and carriage returns such as CR and CRLF can also be used.

-----------------
[ MENU ] - List Send & Edit List
-----------------
You can work with a list of command lists created in advance in [Menu]-[Edit List]. You can send data one list at a time with one touch while viewing the list of commands divided by category. You can also click the [LOOP] button to repeatedly send the lists.The repetition time delay can be changed in milliseconds.

-----------------
[ MENU ] - DWIN List Send & Edit DWIN List
-----------------
With the list transmission function specialized for DWIN's serial display,
You can work with a list of command lists created in advance in [Menu]-Edit DWIN List. Click the [LOOP] button to repeatedly send the command lists divided by category. In particular, for data transmission, random data automatically generated within a specified range is sent. The repetition time delay can be changed in milliseconds.The header is built-in and sent automatically.

-----------------
[ MENU ] - DWIN Curve
-----------------
This is a function to send real-time curve graph data to the DWIN serial monitor. Select a channel, specify a range, and press the [LOOP] button to repeatedly send automatically generated random data at the specified delay time interval. The header for the graph is embedded and sent.

-----------------
[ MENU ] -Multi-DWIN
-----------------
There is a method to send data by generating random data, and an UP & DOWN method that increases from the lowest value to the highest value, and when it reaches the highest point, it decreases to the lowest value again and repeats this action. At this time, you can specify the step of the increase/decrease value.
Additionally, you can change the X and Y coordinate values of the target using two pieces of data.
