Does the Arduino Yun support the WiFi shield?

Official Hardware Classic Yún

Due to the limited functionality of the Bridge library we're thinking of buying some WiFi shields to attack to our Yun boards and I was wondering if there are any incompatibilities, as the searches I did did not give me satisfactory answers.

Up to you to figure that one out for the WiFi shield you want to use. But you wont find it's better than using built in WiFi via the bridge.

You can manage your built in Wifi directly from linux enviroment. How could it be better?

Only time Yun need an other wifi shield or adapter is 5 Ghz support. but WiFi shield is lack that as well.

Just keep in mind that once you go to the WiFi shield, you must manage everything related to the wireless network in the sketch code. And you don't have a lot of code space on the processor that runs the sketch, and that processor is slow compared to the Linux side. You will only have the limited set of functionality that you choose to implement in your sketch and won't have access to all the extra features that are possible with the Linux environment driving the network.

What is so limiting about the Bridge that makes it worth crippling a relatively expensive board with a WiFi shield? I would think that's the last option to consider, and before going that route you should either look for a better way to accomplish your tasks on the Yun (most likely offloading a lot of the work to the Linux processor) or you should go with a less expensive board like an Uno or Leonardo?

@younghyun1,
you can use a wifi shield. It has been done for good reasons. Your reason does not sound like a good one.

  • You can disable the Bridge Library. Handle the traffic yourself.
  • If you use a shield, you will still have a throughput limit, because you will still be using a serial port.
  • You really need to measure your goal, with the tasks needed to accomplish your goal.
  • People in this forum have replacements for the factory bridge library. You need to ask for their replacement.

Best of Luck

Or, describe what problems are being experienced with the Bridge. It may be that it's not being used in an optimal manner, and rethinking the way the code uses the Bridge could fix the issues?
