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.
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
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, Elfège.
Thank you. I was waiting all this time for this promised tutorial (previously mentioned in this discussion). Didn't know it was out already. Since it uses a hex file it should be doable from arduino. If I figure it out I can post about it. Thanks again and again sorry for the frustration... currently my smartthings is crashed again because of bad dns. which means that it impacts my entire house... lights, heaters, all sorts of smart outlets and power meters.
There is no dns server on the ezb.
The dhcp on the current v4 has an issue with some hardware. The upgraded firmware from the tutorial will fix that: http://synthiam.com/Products/ARC
And of course new ones are shipping with the new firmware and don't have the issue so ordering new ones for the school is not an issue.

EDIT: I just deleted what I wrote. I struggle with people who do business like this. The American educational system and a lot of the pompous people who work in it are an embarrassment to the American taxpayer. blush
You're right Dave, that sucked a lot... but be sure that this does not represent the American educational system... I can't give details online but if you look into my fb profile you should find out that this ill frustrated talking was not representative of any US institution.

Since when the new ones don't have this issue any longer ? Because I received two more not so long ago, like a month or two ago and they still have that issue.
@DJ thanks for you kind answer and again, sorry for expressing my frustration this way.
@elfege, Sorry if I came across harsh. Sometimes we say things when we get upset and frustrated. I understand and I'm guilty of the same things many times over. Probably even in this thread. I guess we'er all just human no matter what our ideology is. blush
Happy robot building and hope you get your issue resolved.
Did you get them direct from EZ, or a reseller who might have had old stock. I think they have been shipping with the new firmware for at least 6 months. The AdventureBot I got in November had the new firmware.
The PIK tool is cheap and the flashing is pretty simple. You can also give them recognizable default SSID's which is useful. Just be sure to give each a unique MAC address and don't just flash the default firmware from the download.
