Hello, I would like to communicate with HC-05 Bluetooth device with serial communication (rs232) with SDC2130 model. How should the configuration and scripting program be? Can the hardware connection HC-05 and SDC2130 be made directly? The SDC2130 also has a view pinout 2. pin (txdata) 3. pin (rxdata) is displayed.

Yes this should work. You will likely need to manually choose the com port of the HC-05 in Roborun+. See attached screenshot for where to manually change the COM port:

Dim led As integer
led=GetValue(_CMDSER)
top:
If(led=sol) then
setcommand(_GO,1,500)
else
setcommand(_GO,1,0)
end if
GoTo top

I can not write program for serial communication. Can you write a sample program? My goal is to control the engine with the program I wrote at android. I used the HC-05 bluetooth module for this. When I press the button in the application on the phone, I communicate the word "left" with serial communication. I will write in the driver, this word in the program will run the engine if it comes. I tried to write the program above but it did not work.

There are a few errors in your script. However, if your goal is to receive commands from your Bluetooth device that is connected to the motor controller via RS232 then you wouldn't take this script approach anyway.

You would send serial commands from the bluetooth device. You can see the full reference of serial commands in Section 18 of our User Manual.

For example the serial command to turn the motor in the positive direction at 50% duty cycle would be !G 1 500. To turn the motor in the negative direction at 25% duty cycle the serial command would be !G 1 -250.

thank you for attention. I did what you said communicate with the pc. But I sent it as a scheme I wanted to do. In this case, do you write a sample scripting program?

The commands you are working while connected to the usb cable. But I want to run it by typing scripting via bluetooth module. It helps to cheer you up. Thank you.

Hello,

We have not used the HC-05 Bluetooth Module so we are not very familiar with it's operation and therefore do not have a sample script to provide.

After briefly looking over it's datasheet, I see one major issue with the serial logic levels of the HC05 that will effect its communication with our controller. The logic voltage of the HC-05 module is only 0 - 3.3V. Our controller uses true RS232 so it's logic voltage level is -10/+10V. Additionally I see that the default baud rate of the HC-05 is 9600bps, where our controllers default baud rate is 115200bps. This isn't as major of an issue because this can be changed on either the controller or it appears the HC-05 as well.

Please read through Section 13 of our User Manual . This will detail the serial communication standards of our controller and all the parameters required to establish a serial communication with our controller.
