View source for JUNIPER- WiFi Shield for Arduino Based on GainSpan Module

== Introduction  ==


A low-power WiFi shield that is compatible with Arduino and STM32 Spruce board. Gainspan GS1011 module is a highly integrated ultra low power wireless single chip which contains an 802.11b radio, media access controller (MAC) and baseband processor, on-chip flash memory and SRAM, and an applications processor all on a single package.

The GS1011 module is a highly integrated ultra low power wireless single chip which contains an 802.11b radio, media access controller (MAC) and baseband processor, on-chip flash memory and SRAM, and an applications processor all on a single package.

Along with its embedded software stack it offers a highly scalable, reliable, manageable and secure wireless link to meet the growing demand of wireless sensor networks utilizing the broadly accepted IEEE 802.11b,g,n standards infrastructure.

:CONNECT 0
"Ok
"S0220 smtp105 mail.cnb.yahoo.com ESMTP

*According to command > S0hello worldE specified by gainspan, send to Yahoo mail server by 16 hex through serial.
 
:>1B 53 30 48 45 4C 4F 0D 0A 1B 45
:> S 0 H E L O Enter E
Return EOOS0250 smtp105.mail.cnb.yahoo.com


'''Notes：
# 0D 0A is Enter. You have to add this Enter after HELO string, or there will be no data returned from Yahoo server mail box.
# the key esc on the keyboard and ascii code value. It doesn’t means input esc string.
