I'm currently building a device to monitor and control the fermentation of our home brewed beer using a Netduino Plus 2.

 

Since I don't want to drag an ethernet cable to the cellar I was planning on using a wifi bridge. After some searching I've bought a Vonets VAP11G. I tested the device using a desktop PC without a wifi adapter (also, a Windows computer is needed to set up the wifi bridge. It worked flawless, although the range is bit disappointing.

 

The next step is testing the wifi bridge with my little Fermentator project. And here started the frustration...

 

Although I see DHCP requests on my router log, the IP on the device is reported as 0.0.0.0. Opening a socket for listening or sending results in a SocketException. Changing the IP to static doesn't change a thing.

 

Once I was able to perform some network stuff, but the next reboot of the device resulted in the above behaviour.

 

Plugging in a ethernet cable makes the device run my code happily...

 

My question: does anyone have experience using a wifi bridge on a Netduino Plus? If so, which one did work for you?

 

Kind regards,

Niels

 

PS: I've found one mention of "Vonets" on the forum, but nothing useful.

Hi!

I think Baxter has successfully used this one:
http://www.amazon.co...edimax br-6258n

You can read more about it in this thread:

Hi Hanzibal,

 

I can't seem to find a European dealer for the Edimax, but I've ordered an Asus WL-330N for about 34 EUR.

 

So... let's hope this works better than the Vonets VAP11G I already have.

 

Niels

Assuming you're in Denmark (given the Viking, maybe Roedby) then shipping from China is like 2 - 4 weeks so I can appreciate that.

 

Good luck with it!

I have used the older version (ASUS WL-330gE) and it works just fine. Some setup instructions for the Xbox, but basically the same procedure for all ethernet bridging with this adapter,

Thanks for the H-Online link, but if you click through you'll notice that the Edimax is either out of stock or totally overpriced (2x,00 EUR + 20,00 EUR shipping or 5x,00 EUR and 5 EUR shipping, etc).

 

I'm awaiting the arrival of my Asus and I'll see how it goes.

Do you really need DHCP for a (i assume) home network?

 

Personally i always keep at least 20 ip's out of the DHCP for static and/or multiple ip's etc. typically 192.168.1.234 - 192.168.1.254

Even if you dont take the IP out of the DHCP pool if you set your ND to have an IP of 192.168.1.253 its highly unlikely that your router would ever allocate that IP (unless you manage to get 252 other devices connected to your network) as SOHO routers tend to always allocate up the range i.e. lowest numbers first

Even a static IP results in the same socket exceptions. Since I'm going to open source the project I want both DHCP and static IP solutions to work. Niels
