MATLAB bulk_read_write cannot work

[WIFIwifi8966]

I'm using DynamixelSDK ver. 3.5.4

I'm using MATLAB/example/protocol2.0/bulk_read_write

I'm using USB2Dynamixel2 serial converter

and I'm having an issue:

Running code directly does not allow movement

I have three dynamixel xc330 connected. I would like to read and write position values to them. Using the bulk_read_write.m example under protocol two, I have managed to read and write position values from the two motors.

However when I runned, I get the following message :

[ID:001] Present Position : 2598 [ID:002] Present Position: 0
There two servos could not rotate as the code. So i'm not sure where is the error.

Hello, sorry for the late reply.
After checking the MATLAB example, we confirmed that it is working properly.
When running the bulk_read_write.m file, the output appears as follows:

[ID:001] Present Position : 4022 [ID:002] LED Value: 0

so the position and LED values are displayed correctly.

Did you happen to modify part of the source code?
Or was the “LED Value” section in your previous log mistakenly written as “Present Position”?

Since the values are being read correctly, communication seems to be functioning properly.
If you press any key except ‘e’ in the Command Window and hit Enter,
you should see the position value change and the LED turn on simultaneously.

If you did modify the code, please share your version so we can assist you further.
Thank you.
