WiFi module does not initialize?

I am using a dual USB cable which should be capable of outputting 1A.

Yes it “should” but I wouldn’t trust it. Can you try a powered hub or add a power pack to the DP module please?

No, not all of them are broken. I ordered about 60 units a while ago and I probably have got 40 or so working fine with the new SDK and the new firmware. At the moment 5 of the 60 units fail on initialization at following line:

wifi = new GTM.GHIElectronics.WiFi_RS21(9);

VS pops up following message:

[quote]An unhandled exception of type ‘System.ApplicationException’ occurred in GTM.GHIElectronics.WiFi_RS21.dll

Additional information: Unable to enable WiFi module.[/quote]

And this is what the debug output says:

I have also tried now hooking up a 9V psu to the USB DP board but same problem.

Please email GHI directly for further investigation of the issue please.

What was the final outcome of this, as I currently have the same problem.

Thanks

If you see the same symptoms, it does not mean that it is the same problem.

Please create a new thread with what you tested and what results you got. With a pictures of how you connected it if possible.

Its pretty much exactly what I’m seeing and I have tried:

tried both sockets 6 and 9

different cables

using just a USBClientDP on its own and with a powered hub (note I’m also having a problem powering either of my USBClientDP modules see http://tinyclr.com/forum/21/6576/

tried using a USBClientSP

Tried using a powered USB hub (5v 2A)

tried a setup with just a wifi module

Using Feb. 24, 2012 Gadgeteer Package

Reflashed Spider 1.0 board to ensure latest firmware (confirmed with MFDeploy)

still can’t get past wifi = new GTM.GHIElectronics.WiFi_RS21(9);

no green led on the wifi module

error is Unable to enable WiFi module.

The wifi module is v1.1
The Spider board is v1.0
The USBClientDP is v1.3 (tried also with a v1.2)

What are the current hardware version of the spider and wifi modules as I think I’ll order some more of both and see if the problem goes away that way.
