JUNIPER- WiFi Shield for Arduino Based on GainSpan Module

JUNIPER- WiFi Shield for Arduino Based on GainSpan Module

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.

Features:

• Supports IEEE 802.11
• Seamlessly integrates with existing 802.11b/g infrastructure and utilizes the 802.11 security, manageability, ease-of-use, and quality of service
• 802.11i/WPA2 Authentication, AES Hardware encryption
• Optimized for battery powered application with very low power consumption for multiple years of battery life
• PCB antenna: Range 200-300M+ Outdoor (Typical Estimate)
• Two 32-bit ARM7 CPU @44MHz, 1 for applications (APP) : 1 dedicated to radio (WLAN)
• 2 UART , I2C, 2 SPI, 2 ADC, 3 PWM, and 32 GPIO
• Operates at 3.3V

 Note：
As this WiFi shield shares the same UART port with FT232, when you download the programs, please remove the WiFi shield first.

Effect：Connect to Yahoo mail box（STMP）
>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
Effect：According to command > S0hello worldE specified by gainspan, send to Yahoo mail server by 16 hex through serial.

Notes:
1: 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.
2: is the key esc on the keyboard and ascii code value. It doesn’t means input esc string.
