Cannot Connect

Skip to comments   Jump to end

Hi all,

I hope anyone can help us ...:)

My 8 yo and I are trying to connect our so much expected EZ-B v4 but haven't succeeded so far.

When looking at the connection script we get the following:

connection failed: system.net.sockets.socketexception (0x80004005): No connection could be made because the target machine actively refused it 192.168.1.1:23.

I haven't found another available port apart from this one, and don't know if I need to change the wifi configuration to enable this one?

Any help will be very much appreciated!

Thank you,

Julian and Sofia

Silly question, but do you actually have the new EZB4 board? Or are you just playing with the software until it arrives?... I ask because without the board there is nothing for you to connect to... You won't be using a com port anyway... the new V4 uses WiFi...Have you viewed the ezb4 tutorials... EZB4 connection tutorial? The tutorial will show you how to connect ARC to the new EZB4 board...

Yes, we've looked at the videos, all of them. I was expecting that the robot would use wifi, all we did is we plugged it in and it apeared on our available connections list. When selecting it to connect, it didn't. This is via wifi.

And yes, we have the robot, as mentioned. The boot up chain started, and I'm exactly following the instructions on the tutorial. I also tried the next step, connecting with the software (EZ-Builder)

What robot do you have ? Do you have the V4 ezb (white in colour) or the old V3 ezb?

It sounds like you are still connected to your wifi router, not the EZ-B's network. Try opening a browser and connecting to 192.168.1.1 and see if you get your router's admin page or the ez-b configuration page.

If you get your router's page, you need to go back to your computer's wifi settings and disconnect from your home network, then connect to the EZ-B network before starting ARC and connecting to the EZ-B

(once you are successful, we can talk about being connected to both at once, but let's get simple connectivity solved first).

First connect to the wifi network that the ezb is transmitting. You will need to disconnect from your current network to do this.

Next open ARC and hit connect. If no settings were changed on the ezb it should connect.

If not point your internet browser to 192.168.1.1 to ensure it is an ezb. Also, while in there you can change settings and modes.

If it is the new V4, turn it on (and follow the video) to see it is in your WiFi network list.... then we can work on the next step

I'm about to publish a how to video for connections.

Main steps:

  1. turn on ez-b and ensure the blue light is flashing.
  2. go to your computer and look in the wifi menu. select the ez-b's wifi(usually "EZ-b v4 (ez-b #)")
  3. connect to it and ensure that your computer stays connected.
  4. go to ARC and click the connect button in the "connections" control.

If this is what your doing and it doesn't work try pressing the reset button on the ez-b.(little hole to the left of the logo on the case)
