Hi
I just purchase an WifiBlock for Lego Mindstorms NXT.
Can anyone let me how to to do the following two thing.

1. How to use robotc to read the information from web.

2. How to pass the variable from web interface "ASP.Net web interface" to robotc.

Thx kevin

You should consider reading the examples I have created for the driver in my Driver Suite.
Take a look at HRWB-test1.c and HRWB-test2.c. You can download the Suite from the link in my signature.

Hi Mightor
Hi how are you. Thanks for your help. I try HRWB-test1.c. and it was very useful.

But don’t know why it seems like didn’t connect to my modem at all and also got following error message when I complier.

*Warning*:No indices specified for array variable 'IP'
*Warning*:No indices specified for array variable 'gateway'
*Warning*:No indices specified for array variable 'netmask'

I try following step and try to fix it but still have no luck yet. Can you let me know how to fix it.

1. Change wireless security to WPA and change the password to (AndroidAP 12).
2. Check there 192.168.1.110 is free to use.
3. Check the subnet is correct. (255.255.255.0)
4. Check the default gateway is correct. (192.168.1.254)
5. Check the wifi ssid is correct (AndroidAP)
The only code i changed is
#define WIFIBLOCK_IP "192.168.1.110"
#define WIFIBLOCK_MASK "255.255.255.0"
#define WIFIBLOCK_GW "192.168.1.254
#define WIFIBLOCK_SSID "AndroidAP"
#define WIFIBLOCK_KEY " AndroidAP 12"

#define DO_WIFI_CONFIG 1

Thx Kevin

They're not errors, they're warnings and perfectly harmless.

Are you sure both your WiFiBlock and your phone have been configured to use the same encryption? Does it work with NXT-G? Are you using Infrastructure Mode or Ad-Hoc?
