Hi, can anybody advice wich one from this two wifi modules: Wifi RS21, IoT Labs WiFi module is the best choice for Cerbuino bee mainboard. I already know that iot labs module can handle about 20 simultaneous sockets… how many sockets can handle wifi rs21? thank you…
Now i am using an RN-XV Wifly module in my project, but due to it can handle only one socket connection i want to try another one…
@ Alex Bilityuk - The WiFi RS21 is not compatible with the Cerb-Family, FEZ Cebuino Bee included.
Thank you for quick reply, how about iot labs module? is it compatible with cerbuino bee?
And I want to add is that our RS21 support is the only WiFi support with actual “Socket” interface. It is the only one that hooks right into the internal TCP/IP stack in NETMF.
@ Alex Bilityuk - I have not tested the IoT Labs Wifi module with a FEZ Cebuino Bee, but the Bee does have a ‘K’ socket which is required, so it should work (as long as the hardware handshaking is functional).
@ Gus is right that actual “Socket” is not supported on the IoT Labs module, but it does have a similar concept, “WifiSocket” that is used in a number of different class that come with the SDK. You can download the SDK from http://iot-labs.net/sdk/il-g-wf121sdk.zip and it contains the help file for the module.
Ok! Thank you! Let me know please if you test it with cerbuino bee

Now i have not only a Cerbuino bee, also i have a Raptor device.
Can you tell please me how many socket connections the RS21 can handle simultaneosly?
@ Alex Bilityuk - The limit is not with the module but the internal lwip stack. In the current pre-release the maximum number for the G400 is 64 TCP sockets, 32 UDP sockets, and 24 listening TCP sockets. I have noticed that the actual working limit is a bit below that though in practice.
I would not rely on these numbers too much as they are subject to change between SDKs.
