Hi, I'm trying to build the Wall-E robot using wifi. I am using the UART-Wifi suggested.
Do I need an arduino to make this work with EZ-B?
And I tried downloading the wifi software from elechouse but it gives me a .rar file which tries opening with iTunes. I can't find the .exe file?
This project is due in a week as a CAPSTONE project for my school and I am pretty behind. If anyone can help I would appreciate it!

Connect the Wifi Module to the USB module as the instructions.
Run the set up software for the wifi module
Set it up, details are in the other topic.
If set up correctly with the WiFi SSID, password and port number it should connect to the WiFi network - check your router to see what's attached via WiFi to confirm.
Open your internet browser
In the URL box type the WiFi modules IP then a : and then the port number (i.e. 192.168.0.3:80) - the password if you don't change it is 000000
Make any changes to the set up in the web based set up.
Restart the Wifi module
The red light should flash fast to indicate automatic connection to your wifi
Then, connect it to the EZB. Details are in the topic linked to.
It needs at least 300mA and 3.3v to power it, the EZB may not give it enough current (this is where mine is waiting).
Power up the EZB and the WiFi (if external 3.3v supply)
Red light should start flashing fast when connected to WiFi
In ARC connection don't select a com port but type in the IP of the wifi module then a : then the port set i.e. 192.168.0.3:6666
Hit connect
Thanks @rich but on the Uart-wifi software I have not been able to select a port and set it because it won't find a device when I hit search. I have tried COM6 and AUTO with different baud rates and nothing is found.
And the software won't let me modify the other settings.
Select the correct COM port (only you will know this) and search. When it finds one it'll probably give an error about reading the data, ignore that. Then set up the details, modify, reboot the module and it should auto connect.
So I chose that on the configuration and still nothing. I get a message when I click search that says:
Cannot find the device. The possible reasons are as follows: Com is invalid, device is not connected.
The red D2 light is on, yellow D1 is on, and Green D3 light is on on the USB board.
Try swapping Rx and Tx over on one of the 2 boards
What are the lights on the WiFi module doing?
Put it on 3.3
I do not have the jumper wires, I'll try to go by radio shack in the morning and let you know. If radioshack doesnt have them I'll rig something up with what I have.
Connect the USB and the WiFi together like this
Connect the USB to the PC
Open up the configuration program
Select the COM port
Click search
Change the settings to your settings (don't copy mine from below)
Set Auto Workmode to on
Details as my picture below (you can change your port if you wish)
Click Modify
It'll ask if you want to restart now or later, choose restart now
Open your web browser and type in the URL box the IP address of the WiFi module (if set static like I did you should know it, otherwise check your router's attached devices or use a network scanner to find it)
Log in, username is admin and password is 000000
Make any further changes here, if needed (it's easier than in the wifi program)
Save if changes are made.
Only now are you ready to connect the WiFi module to the EZ-B
