I could use a little help with a uC32 and Wifi shield MRF24G0MA.

I thought I have the libraries downloaded and installed: Volume in drive C is Gateway Volume Serial Number is 9EF6-6ED3

I have tried to run the scan but it fails with

Start of Sketch WiFiScan 3.0 Digilent, Copyright 2014

Start WiFi Scan Scan Failed

Status value: 268443650 End of Sketch

The comments say it is for my board I think.

I also tried

//#include <MRF24G.h> // This is for the MRF24WGxx on a pmodWiFi or WiFiShield //#include <IM8720PHY.h> // This is for the the Internal MAC and SMSC 8720 PHY #include <WiFiShieldOrPmodWiFi_G.h>

but it can not find the .h file

MPIDE version is 0150-windows-02150204-test

Running the scan program in DWIFck I get Start of Sketch WiFiScan 3.0 Digilent, Copyright 2014

Start WiFi Scan Scan Failed

Status value: 268443650 End of Sketch

Below is the script I used to demonstrate WifiScan and the HTTPServer examples recently on a WF32. My understanding is, the same code will work for uC32 and WiFi Shield without modification.

A couple to things to note:

• When using the ...0204 test release, all the necessary libraries are included automatically
• Be sure to save the HTTPServer demo in your sketchbook, so you can modify the HTTPServerConfig.h file (examples are by default read-only.)
• After you modify the .h file, be sure to save it explicitly

Hope this helps!

1. Plug in portable router, SSID: chipKIT, pswd: microchip
2. Connect laptop
3. Open browser, navigate to chipkit.net
4. Show the products page
5. Show the Getting Started: Install Software page, scroll down and navigate to “…test releases”
6. Show the test release dated “…0204”
7. Open the MPIDE, after installation
8. Open File:Preferences to verify the Sketchbook location
9. Open File:Examples:Basics:Blink
10. Look on Tools:Serial Port
11. Plug in the WF32
12. Look on Tools:Serial Port again
13. Select Tools:Board:chipKIT:chipKIT WF32
14. Click “Upload” icon to compile and load the sketch
15. Verify operation, slow blink on user LED
16. Open File:Examples:DEWFck:WiFiScan
17. Click “Upload” icon to compile and load the sketch
18. After loading is complete, open the Serial Monitor
19. Wait for a report of Access Points to be printed
20. Open File:Examples:HTTPServer:deWebServer
21. Click File:Save As... to save this example in the sketch folder
22. Click on HTTPServerConfig.h file
23. Scroll down, and change two lines for SSID (chipKIT) and password (microchip); and save the file
24. Navigate to <install folder>/hardware/pic32/libraries/HTTPServer/examples/dsWebServer/Content

• copy all of these files to a uSD card
• insert this card into the chipKIT WF32

25. Click “Upload” icon to compile and load the sketch
26. After loading is complete, open the Serial Monitor
27. Wait for a report to be printed, and copy down the IP address
28. Open a web browser, connect to the “chipKIT” network
29. Open a page at the IP address, recorded above
30. Click on “The chipKIT MPIDE System” to demonstrate files served from the SD card
31. Click back, then “Posting a Form” to show an interactive web page, with buttons and LEDs

version 204 is installed. I am removing it and re-installing.

When I got to step 19 I received the following on the serial output:

Start of Sketch WiFiScan 3.0 Digilent, Copyright 2014

Start WiFi Scan Scan Failed

Status value: 268443650 End of Sketch

Doesn't look right to me.
