EZ Gui is commonly used in controlling two different projects, which are drone and self balancing robot. But when we use the EZ Gui, we faced a lot of problem in controlling our projects. This errors and problems of EZ Gui create a new challenge in front of the developers. However the most common problem of EZ Gui is “No Data Received”. Almost every user face this type of issue while running this application. Today I will give you the solution of “No Data Received” problem. If you follow the basic steps that I have mentioned bellow, then you may get rid of this problem. But before this you have to check some parameters of your project. If everything is fine then only you follow the mentioned steps to avoid “No Data Received” issue.
Here we are considering the project of self balancing robot. Check the following things before you go further –
(1) The error of no data received is coming due to the problem of serial communication. For this you have to check all the parameters of your Bluetooth module HC-05. Majority of the people do not change the baud rate of Bluetooth module to 115200. If you don’t change the baud rate, there is a problem of serial communication between the Bluetooth module and EZ Gui. To change the baud rate, open the Arduino IDE software and write down the below code -
AT+UART = 115200,0,0
To check the present baud rate of your Bluetooth module you have to write down the code mentioned here –
AT+UART
(2) If you followed the first step fairly, and still the problem is not going then you should follow the second step. You have to check the condition of your Bluetooth module. If there is any problem in Bluetooth module, then you may face the problem of no data received. It is always recommended that you should always use a new Bluetooth module in your project. If you still having the same issue, then you can replace the Bluetooth module with another one and keep checking.
If you already follow this mentioned steps then you should go to the EZ Gui application and follow the steps listed below –
(1) Open the EZ Gui application and connect it with the Bluetooth module. During this process you may see a check box written as “No Data Received Warning”. Simply you have to uncheck the box and then continue the further process. For better understand you may follow the picture below.
(2) Now come to the model control option. At the top right corner you can see option of changing the settings. Click on the settings options. A new screen will come in front of you. At this page you will find the option of changing the refresh rate. In general the refresh rate of the application should be more than 100. So you can set the refresh rate as 200. When you have done this step the problem of no data received may vanish. But if you are facing the problem again, you may change the refresh rate to a higher value like 500. For better understand you may follow this image.
