Uart Wifi

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.

Hello Alan, I'm sorry to hear you wasted your time and money.

Let's hope that DJ and his team will think of the following improvements :

  1. have the server option to work through port forwarding so we can connect one ARC to another one from anywhere and not only from local network.
  2. A new firmware for EZB that would allow wifi shields (I too had no one working otherwise than through serial port forwarding software : I tried 3 different modules).

Best, Elfege

Server should already work over WAN if port forwarding is set up correctly. I've not tested it but in theory, if your router is set to forward traffic for port 6666 to 192.168.0.8, using your WAN IP or a DDNS service you should be able to connect in from another ARC on your LAN or over the internet.

Theretically, indeed... but I couldn't when I tried to work it arround last time. I should try again. I wonder if anyone did it already. I think it's possible only if ARC sets works as a vpn, as it is supposed to do for the http server for example.

I can connect via telnet from my phone running on mobile data to my LAN over the internet which I believe is what it's based on. If it didn't work for you I would check your port forwarding options on your router.

I connect everyday to my lan over the Internet : 3 ipcam a NAT based hard drive + other features. Can you telnet your ARC's server from your Iphone ?

Grrr... so what's going on in my config ? Seriously! I must have something such as firewall blocking outside coms to this LAN for certain protocols... I don't get it. It's like my ip cam that I can't connect to EZB while you can, using the same model...

Hello,

Using HW I can connect over the internet to my EZB using the SR232 module we were initially talking about. The problem came from either my ethernet adapter on my pc or from Hamachi VPN network that was running. i suggest you turn off all VPN and network adapters running on your computer and try with another adapter if you still have the buffer error message. If it still doesn't work then change the port settings in port forwarding. Another thing I did was to set a different external and internal port (not using 80 port at all) in my router for the wifi module.
