  • You are now ready to upload the Wifi Test Code to ensure everything is working properly. The Wifi Test Code can be found on the Arduino IDE by using menu File->Sketchbook->Example Codes->WifiTestCode

  • To be able to connect remotely to your controller from outside your wifi network, you will need to setup port forwarding on your router. The TCP port you need to forward to your wifi attachment is port 2000.
    Most recent routers have UPnP capability. This utility will try to setup port forwarding automatically on any UPnP capable router that is compatible with the UPnPLib Java.
  • If the utility is successful on setting up port forwarding on your router, you will get a message below:

Did you upload the WifiTestCode to RA?
Have you plugged the wifi attachment to RA after uploading the code?
Make sure you have the port after the ip address. By default the port is 2000. So you need :2000 after the ip address.
If you are using IE, you also need to make sure that you have http:// in front of the ip address or IE just won't understand and will think you are trying to search something.

Should the interface with the installer look like the tutorial? Mine looks the same as the old one with the same functions. I have recently removed all my earlier reefangel programs and updated to the latest stuff including the new libraries.

Is your wifi network on WPA2-PSK with AES encryption?
I'd highly suggest using this security scheme.

Hi Roberto this is what I have , like is readed from the Belkin Router I´m using:

In the Channel and SSID tab:

SSID > XXXXXXX (7 letters)
SSID Broadcast> Enable (other options : Disabled)
Wireless Mode> Mixed (11b+11g) (other options 11g only, 11b only, off)
Extend range> Disable (other option: enabled)
Protected mode> OFF (other option ON)
WMM Mode> ON (other option OFF)
Turbo mode> Disable (other option Enable)

In the Security tab:

Security Mode: WPA2 only > (other options: WPA/WPA2, WPA only, WEP, disabled)
Authentication: Password(PSK)
Password(PSK) type: Passphrase (8 ^63 characters) > (other options Hex (64 digits)
Password(PSK): xxxxxxxxxxx (11 letters and numbers)
Guest Password(PSK). yyyyyyyyyy (10 letters and numbers)

In the Wifi protected setup (WPS) tab:

Wifi Protected setup (WPS) : enabled

option 3) Manual configurtion method
Network name (SSID): XXXXXXX (7 letters the same as above)
Wireless security: Configured
Network authentication: WPA2+PSK
Data encryption: AES
Network Key (PSK): xxxxxxxxxxx (11 letters and numbers, same as above)

In the Use as access point tab:

I tried to configure through Wifi_Utility with :


and get:

Your Reef Angel Wifi Attachment is now configured
*Wifi* Status
Associated: true
Authenticated: false
DHCP: false
Mode: WPA2
IP adress and port: (remember that I used the "Restore Factory Settings" before, and since then the IP changed to this)

and the blue and green leds blinks

Any advice on how to solve this really apreciated
