@Alan : indeed it works and I could make it work too, not through direct ip though. However it seems pretty precarious for a permanent solution since it needs some regular intervention on the device itself such as power cycle. Perhaps I'm doing something wrong but this is the second one that stopped working properly on my side...

One point I may have forgotten to mention is that I am powering the WiFi module using standalone LI-ion cell phone batteries. Each battery is rated at 1600 mAH. I wire two together in parallel for a complete battery pack that provides 3200 mAH at 4 volts dc. I just got some dc to dc converters from China that can operate with a dc input of 9 to 30 volts and provide 3.3 vdc at 5 amps output. I plan to modify the LI-ion pack and add more cells to increase input voltage so that I can test these new regulators. I would like to make sure that the slowing down of the application is not due to power input to the WiFi device.

Although I can connect most of the time without issue I'm now finding that there is an issue with transmission capacity that degrades with the addition of more than one IR or ultrasonic device to the screen.

If/When I get it working and stable you can expect to see a step by step guide on it. I'm sure you're aware of the level of detail and clarity I put in to such things so if I can do it I'm confident we will get yours stable too.

Having had mine powered by USB on the PC for over 24 hours with no issue I don't see that power cycling will be required once it is powered correctly, with enough current to maintain the connection. Hopefully this doesn't offend you as that is not my intention but I am leaning more to the side of user error than a problem with the module.

On the other hand, I don't accept sub standard kit so it could go either way but I wont give up until we have a definitive answer on this module one way or the other

@Robotdoc, how often is it checking the IR? I know there can be issues with checking multiple ADC ports frequently. My bluetooth benchmark shows it can read from ADC 25 times in 1 second, so if it's set to check every 200ms it will be capable of reading 5 sensors (5 sensors, 5 times a second each = 5x5 = 25). It may pay for you to run a benchmark (benchmark control is in general in ARC I think) and see what the limit is. That is important to a lot of builds and if WiFi is low it will be worth noting for anyone looking to go down this route.

It's checking the Sharp IR radar at 500 ms and the radar scan at 250 ms. All I did was add one digital and one analog port taking the defaults from EZ-B.

Don't worry Rich, none offense to be taken since I'm perfectly aware of the fact that I suck! I'm just who I am : French! I'd rather accuse the second module I burned than myself ! Looking forward to reading your tutorial !

By the way... I suck so much that I cannot make my new robot to turn, (I burned the old rovio eventually because of my two system in one... I know, I know... you told me ) so I put everything on a 4WD platform with an HBridge (I strictly followed DJ's tutorial for that part) and the only way I get the platform to run is by stripping out the rear wheels from their rubber so there's less friction and it can turn. It seems that while given the order to turn the Hbridge runs the wheels on both side at the same speed while the wheels on the inner side should run much slower than the wheels on the outer side, is that correct ? If so, do you know what could possibly allow me to have the inner wheels to turn slower beside using PWN each time I want to turn ?

@elfege, it looks like you went off topic for this thread. You may get someone to answer your question in a new thread.

@elfege Hello i have read your post. like you i am also stuck with wifi module i have made some changes to use webserver on this UART-Wifi module i have achieved it successfully. Now i am not able to connect it again with UART-Wifi configuration software. www.elechouse.com/elechouse/images/product/UART%20WiFi%20Transparent%20Module/UART-WiFi_English.rar I am getting error "no valid com found". i tried to hard reset the module by connecting pin 2 to 5 and then 4 to GND temporary. but no result. I have followed your post and apply the solution as per the pdf you posted(on page 121). but still my module is not responding. Now i am also not able to configure it over WiFi. so how can i achieve Hard reset? can you please help me?
