Can't Use the Wifi Rs21 Module in spider

I want create a new Gadgeteer 4.2 Project.
When I drog the Wifi R21 module form toolbox to Program.gadgeteer.
It shows The module could not be added: -A required library could not be fund.

How to solve it?

My SDK infor.
ClrInfo.clrVendorInfo: Microsoft Copyright © Microsoft Corporation. All rig

What mainboard are you using?

I think this module is only compatable with the premium boards like the Spider.

I use the Spider.

If I create the 4.1 Project, when deploying, it will shows Error 1 Cannot deploy the base assembly ‘mscorlib, or any of his satellite assemblies, to device – USB:Gadgeteer twice. Assembly ‘mscorlib on the device has version, while the program is trying to deploy version 4.1.2821.0″ .
How to solve it?

sounds like the Spider has 4.2 firmware so that would mean you need to create a 4.2 project

Isn’t Wifi one of the “pending” items on the 4.2 readme/known issues list?

Flash your spider with the 4.1 firmware and deploy your 4.1 app. That’s easy.

Thanks, I will down the firmware to 4.1 then try.
GHI has many types of product, thats good, but different firmware always make me depressed.

I wandered through the firmware weeds last week over this exact same thing, basically what I found works is this:

  1. Install both the 4.1 and 4.2 GHI SDKs if you haven’t already.
  2. Uninstall the 4.2 Gadgeteer SDK, install the 4.1 Gadgeteer SDK
  3. Use the 4.2 GHI firmware updater, pointed at the 4.1 GHI firmware files (I think they’re something like CLR.hex/CLR2.hex/Config.hex), to “update” the Spider to a firmware package that will work with RS21.
  4. Create your project as a NETMF 4.1 project, make sure all your assemblies are pointing to 4.1.2821.0, and away you go. Recommend trying to deploy a dummy project first to verify it works…if a fresh project prints “Program Started” in VC#'s Output window, you’re good to go.

Not sure why step 2 is needed above. Still, we are very concerned and working hard on finishing WiFi so no one would have to use 4.1

Hi, where can I find the 4.1 firmware of spider?

Is it not in the 4.1 SDK & Gadgeteer download on the Support page (#4)?

But the SDK is .msi file.
I have installed the 4.2 RC2 8-24-2012. I don’t want to remove 4.2 because I have FEZ Cerbuino Bee.
If I only want to install the 4.1 firmware of spider, where can I find it .
Thanks you very much.

it’s in the separate 4.1 SDK download ; on the same download web page. Install that SDK as well as the 4.2 one (they work alongside each other). Then use the 4.2 firmware udpater but use the 4.1 firmware files.

I added a another section to this page GHI Electronics – Where Hardware Meets Software

Thanks Gus.
