Hello,
After unsuccessfully trying the UART WIFI suggested by this website, mainly because of power issues though I could have it to work and run for a little while, I tried another UART WIFI which seems much, much, much more reliable and user friendly since it has its own AP mode which allows you to configure it through web interface directly (you do not need to connect it to USB TTL module) and a quite efficient factory restoration process in case you input the wrong settings.
The model hardware name on Amazon is "Embedded Wifi To Serial Module RS232UART WIFI Board Module External Antenna"
I can get a connexion to EZB using both methods : typing directly the IP address + port into ARC's connection or through serial emulation.
However, when I use serial emulation (HW virtual serial port) I get a repeating message such as : "Disgard incoming buffer (This should never happen)"
And if I connect through IP address directly I get something really weird : it says that I have to upgrade the EZBoard firmware and, most of all, it shows different versions numbers : 24.x , 14, 17...
Here is the full debug report in cas God (DJ) took a look at it. I remember someone had ordered the same device so I'm posting this in case he found the proper settings. I set the module to 9600 bauds, TCP server mode. Let me know if you need more details.
Here is the debug report.

You may not need any password, the box comes up when connecting to another instance of ARC, which can have a password but doesn't need one. If none is used just clicking OK or cancel works.
What I disdcovered is that when any charactors are typed into that block, you get an error and the Version number changes to other versions like 4.1, 7.2, etc. I finally got one of the two WiFi boards from Amazon.com to connect by only using the virtual comm port.
If the device is configured correctly, there is no reason why it should be an issue. The EZ-B is TTL (3 or 5 volts works). The EZ-B is not RS-232. The EZ-B will automatically adjust baud rate between 300bps and 115,200bps during connection.
By default it is recommended to use 9600 for best use of ARC control timing.
Some suggestions:
As for the UART timing settings - I have no idea what those are. I can't even understand what they could be?
Thanks for the tips DJ, the WiFi board from Amazon.com is powered using a 3.7vdc LI-ion pack and the communication is at TTL levels not RS232. The WiFi admin page was changed to 9600, 8,N, & 1. No option for local echo and CTS, RTS were turned off. Success was achieved only by the virtual comm port.
Would you send me the name of this board or, better, a link to the amazon product ? I'm eager to finally have a wifi working on my project. Can you also let me know which port redirector you're using ? Is it HW ? If so, what are the settings you picked in the settings tab ? Thank you.
@elfege, I have the same board you discussed on the first page of this thread.
Here are the HW serial port settings:
Here's a pic of the WiFi board
And it works through com forwarding ? You gained control of the EZB ? because I did the same... and it didn't work. I'll try again and see what I might have missed. Thank you !
Sorry to bother you again but would you send a picture of the wifi WEB app config ? Because I still get "disregard incoming buffer issue".
