GainSpan Wi-Fi library
The GS1011 is an ultra low power 802.11b wireless module from GainSpan.
see: http://mbed.org/users/gsfan/notebook/gainspan_wifi/
Information
Please change the baud rate in advance.
- ATB=115200
- AT&W0
It may be better and sometimes faster.
GSwifi gs(p13, p14, baud);
Heavily modified new library: http://mbed.org/users/gsfan/code/GSwifi
ゲインスパン Wi-Fi モジュール ライブラリ
ゲインスパン社の低電力 Wi-Fiモジュール（無線LAN） GS1011 シリーズ用のライブラリです。
解説: http://mbed.org/users/gsfan/notebook/gainspan_wifi/
Information
モジュールはあらかじめ次のコマンドでボーレートを変更しておく。
- ATB=115200
- AT&W0
場合によってはもっと高速の方がいいかもしれない。クラス宣言時にレート設定をする。
GSwifi gs(p13, p14, baud);
