Connection Troubleshooting



This tutorial explains how to connect to an EZ-B from your Windows PC. This is a generic connection tutorial and not specific to any robots. There are specific connection tutorials for each style of robot on the Getting Started Guide. However, for connecting issues, use this tutorial.

Anti Virus for WiFi Controllers

Antivirus Software - This is the number one connectionn issue for WiFi controllers, such as the EZ-Robot EZ-B v4 or IoTiny. There are many reports of connection issues with PCs running Antivirus Software, such as AVAST, McAfee, Norton or Norton Internet Security. If your PC has Antivirus software installed, please disable or uninstall it. Nearly all of the WiFi communication issues are related to anti-virus software. Simply disable the virus scanner before posting a message.

Arduino and USB Controllers

Arduino and USB controllers have tutorials for connection on the Getting Started Guide. However, the leading cause of connection trouble with Arduino is the baud rate. Ensure you have followed the Getting Started guide links to configure ARC to the correct baud rate. Additionally, providing proper power to the controller is important as well.

Connect to EZ-Robot controllers via Wi-Fi

The default EZ-B v4 Wi-Fi setting is AP Mode (also called Wi-Fi Access Point or AdHoc). EZ-Robot has tutorials on how to change the WiFi mode can be accessed HERE.

DIY Robot Builders (Power related)

If you have an Arduino or EZ-Robot developer kit and the EZ-B is disconnecting, chances are that the batteries or power source is not providing enough current for the servos. When this happens, it is called a "Brown Out". That means the EZ-B controller is not getting enough power when the servos move. In this case, the only solution is to replace the power source with higher amperage. A wall-wart (power adapter) will not provide enough current for electro-mechanical servo motors. The ideal option is to purchase a LiPo Battery, Balance Charger, and LiPo Battery Harness. If you're convinced to use an adapter for power, there are also 2 great tutorials created by EZ-Robot users HERE and HERE.

Guide: Forum Posting For Assistance

If you are still having trouble connecting to an EZ-B, this section below contains trouble shooting steps. If you are ready to post on the community requesting assistance with connection issues, it is mandatory that you answer these questions in your forum post.

  1. What product are you connecting to? (i.e. EZ-Robot, Arduino, Raspberry Pi, JD, Robotis Bioloid, etc).

  2. What power source you providing the robot?

  3. Does the robot make a startup sound when powered on (if applicable)? Is there a verbal message spoken from the EZ-Robot products? If so, you may need to reset The EZ-B v4

  4. If EZ-Robot product, what color is the light on the EZ-B and is it flashing or steady? (Flashing Green, steady blue, white, etc)

  5. If WiFi device, are you connecting the device to the WiFi network of the EZ-B v4 by following the video instructions on this page?

  6. What error message is displayed in the status window at the bottom of ARC? Press the COPY button on the status window and paste the contents in the forum post.

    • If an error appears, some devices take up to 1 minute to detect the ezb - wait 5-10 seconds and press connect again.
    • Note: do not change or modify the IP address field on connection screen. Use the default value.

  7. If a connection still does not occur, are you certain your device is connected to the EZ-B v4 via Wi-Fi?

  8. Have you double checked the wire connections to the EZ-B v4 using the very helpful learn section on our website? Ensuring the black wire if all plugs matches the black side of the ezb connections? Etc...

  9. Reset the EZ-B and repeat this procedure if you are still experiencing issues.
