Fork of GSwifi_old by gs fan

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);
