Community Question

Just tried to upgrade one of my robots with EZB V4 hopping to get something much faster and also to overcome some serious issues and limitations due to EZB V3 losing Digital ports one after the other.

1) This expensive piece of hardware does something totally unbelievable : it CHANGES MY NETWORK'S GATEWAY to its own client's address... How is it even POSSIBLE ? *confused*

2) Both the EZBs' I got are EXTREMELY SLOW. If I don't disable most of the sensors connected to it, and this EVEN in AP MODE, digital ports will simply take up to 30 seconds to respond. In AP mode N mode it is a little bit faster, but still at a pace that makes running any script useless. I also varied the milisecs for all of them, even at 2 seconds delays I have some little improvement only and no one can seriously hope to use a 2 seconds delay on an IR sensor, right?

I tried from different routers, without routers (AP modes) and the only thing that will make it work properly is turning off almost all sensors (2 ulstrasounds, 3 IRs', 2 currents meters and a lux sensor).

Has anyone met the same 2 problems ? I will try to change the power source, especially the power regulator that I use and see if it does something in terms of transfer rate. For the first SO WEIRD problem, here, I'm stuck... no idea what could do that the EZB takes over the router's address on my network forcing me to set all my computers on fixed ip addesses... . It should not be possible at all.

Thanks for your help,
Elf├Ęge.

I have been off these projects for a while so please excuse. Basically what is said here is that we must upgrade the firmware by buying the kit, not directly like V3. I tried on network and access point and both there is too much lag time. Different PC also. No good on the speed.

Depends what version of the ez-b v4 you have.

Tried using interface says unable I guess this early version. I am really have a lag between pc and V4. Run same program on V3 works great. same equipment. Could the problem be the Hbridge?

1) The problem is generally 99% user code - meaning, what are you doing with it? Share the project for someone to take a look at

2) Also, how are connecting to the wifi? Is it direct adhoc or client mode through router

3) lastly, you can check what version of wifi you have. There's a the robot program episode that shows or you can READ the ez-b v4 upgrade page here: http://www.ez-robot.com/Shop/AccessoriesDetails.aspx?prevCat=101&productNumber=51

My code is up on your site called Vetrobot. Tries connecting both modes. Using Win 10 on 2 different machines. latest version of your software. Lag time is between 2- 10 seconds. My laptop which runs nothing else and was ok with V3. I do not believe it is the code. Tried with and without script also. Tried with and without joystick either.
