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.
Does your EZ-B make a chime when the power is applied? Such as demonstrated in the tutorial videos
Have you been able to connect to it before?
@DJ
Do you think it is more a problem with the board itself ?
Did the EZ-B make a chime when you had first got it?
@DJ Yes it did (I remember i found the sound really loud for such a small board
)
And sorry for the delay in my responses (time zone differences)
are there any lights flashing if not check the fuse and battery
It sounds as if the EZ-B chip has been damaged and is no longer functional - which is why you are unable to connect - and why it is not creating a bootup sound. Obviously a very rare occurrence due to a short, incorrect wiring, or too much current draw from something connected to it.
@DJ
If the chip is damaged, is it normal that the board is seen at the address http://192.168.1.1 in AP mode and that I can pass through AP mode and Client mode (blue light to green light)? Also I can connect to the EZ Cam at the same address.... Maybe only some specific part of ship is damaged, then.
Moreover, I don't see what incorrect wiring or overload might happen as I have only connected EZ-robot servos and Cam so far.
But the real question is: what can I do about it ?
Clearly, as I have received my EZB a long time ago (more than 1 year) and even if I didn't use it so much, there must be no more warranty... So if there is some crazy soldering I may try, please let me know...
Oh - do not worry about soldering
We made the board modular so only one piece would need to be replaced.
The EZ-B v4 has two chips on it, which is why you can configure the web server and view the camera. The Wifi chip is working for you, and that allows those functions to continue working.
The second chip is no longer working - and that would be the root to your trouble. This is how you can tell, when the EZ-B is powered up the CHIME and a RED led will be lit. Here is a video demonstrating how the RED led should be lit during bootup...
