Serial Communication Error

I'm attempting to control the Bioloid robot now using the wireless Zigbee module now but I'm running into some new errors now. I've written a very simple code just to test the wireless communication as shown below:

Code: Select all
 
START PROGRAM {
       
      ENDLESSLOOP{

                if(REMOCONARRIVED == TRUE){
                     MOTIONPAGE = 7
                 }

      }


}



In this case motionpage = 7 is the demo page for Bioloid dog standing up. However when I try to transmit the command through Roboplus terminal the Bioloid does not seem to respond to it at all.

I currently have one Zigbee module attached to the CM-5 board, and the other is mounted on the Zig2Serial attached to the USB2Dynamixel which is attached to my computer. After connecting through the appropriate COM port (COM 6 for me), I try pressing a few buttons in Roboplus Terminal. The TxD light on the Zig2Serial flash followed by the RxD light on the CM-5 however the Bioloid does not respond. Can anyone help with this?

Note the status light on the Zig2Serial is solid and the serial cable is not plugged into the CM-5 at this time.

dnhan,

When you RoboPlus Task checks for REMOCONARRIVED the following action occurs. The input buffer is scanned to see if there is a valid remote control communications packet present. If a packet is present the two-byte code is saved for later retrieval and the REMOCONARRIVED flag is set to true. If you transmit unformatted data it will be skipped over when the program searches for the 0xFF, 0x55 packet header.

See this page for information about remote control data packets. http://support.robotis.com/en/product/auxdevice/communication/rc100_manual.htm.
