ARC Connection Question

Skip to comments   Jump to end

Hi everyone,

I have been kept away from this forum (and robots) for a looong time but I am back again:) So, I try to connect ARC with my EZB-v4. The problem is, it doesn't work...

First, I have looked carefully at the tutorial and everything is clear. Second, it doesn't seem to be a wifi issue :

  • in AP mode, I can see my EZ-B v4 0282 wifi network in windows (seven) and connect to it. I can then access to http://192.168.1.1 but when I go to Diagostics, I can hear no sounds. When I try to connect in ARC, the blue light stop to blink for 4 seconds and I have the "could not connect to the EZ-B" message. So, I go to Client mode....
  • in Client mode, the EZ-B blink green and It seems that it do not connect to the network (no message of success from the EZ-B). Yet, in my router configuration panel, I can see the EZ-B, and an IP address is assigned...But again, when I try to connect in ARC with the assigned ip, I have the "could not connect to the EZ-B" message and if i try to detect the EZ-B with the scan option, it finds nothing.

I am not a specialist, but it seems that my PC, my router and my EZ-B are able to communicate and see each other, but ARC cannot connect with the EZ-B. And I cannot see why...

So any help is welcome. Thanks.

Have you tried disabling anti-virus? Is the PC a HP PC? Is the speaker connected to the underside of the EZ-B? Can you connect from an android device?

fredebec, Try resetting EZB with a pin or pen to default, back to AP Mode. Look at your internet options again to see if EZ Robot shows? Sometimes recycling power on your PC and EZB helps. Try connecting if it shows, then try connecting in ARC. Does your camera show? Steve S

Yes, no effect.

No, it is not.

I am not sure what you mean by that. I have the EZ-B still integrated in its box as I received it, so I'd say yes.

I have tried with my galaxy tab with no success.

Hope it helps...

@Steve S,

I have reset the EZB many time, with many cycle AP mode ->Client mode, but it didn't work. I can see the EZB on my network, but ARC cannot connect...

What's in the debug in ARC after a failed connection attempt?

@Steve,

In AP mode, I can connect to the camera in ARC by looking at the adress 192.168.1.1:23

@Rich,

It depends. I have either a simple :

Quote:

04/03/2015 23:25 - Attempting connection on 192.168.1.1:23 04/03/2015 23:25 - Connection Failed: System.TimeoutException: Le délai d'attente de l'opération a expiré. à EZ_B.EZB.Connect(String hostname, Int32 baudRate) 04/03/2015 23:25 - Disconnected

or a more complicated :

Quote:

I am sorry, most of the text is in french...

I have both messages either in APmode or in client mode.

Were those messages from AP mode or Client mode?

And you are sure the IP address is 192.168.1.1 in client mode (if the message was from client mode)? Or do you change that for the IP of the EZ-B? Including the :23 after it?

It's timing out which would indicate that some software is stopping the connection (AV or similar) or the IP address is incorrect.

The messages come from AP mode. When I use Client mode, I replace the address by the one assigned by the router to the EZB (192.168.0.21:23) and I have the same messages. So it don't seems to be a problem of wrong IP address. From your suggestion, I will try to find if some software is blocking/stopping the connection (even though I have no idea which one could do that). I'll do it this evening (I am at work now). Thanks for the help...
