Arduino Stackable Uart WiFi Module Kit


This WiFi module has UART interface. And it is more powerful, with more functions




Summary

TLG10UA03 is a new embedded Uart-Wifi modules.

Uart-Wif is an embedded module based on the Uart serial,according with the WiFi wireless WLAN standards, It accords with IEEE802.11 protocol stack and TCP / IP protocol stack,and it enables the data conversion between the user serial and the wireless network module. through the Uart-Wifi module, the traditional serial devices can easily access to the wireless network.

TLG10UA03 does a comprehensive hardware and software upgrades based on the products of the first two generations, now it’s more functional and more convenient to use,its main features include:

1、Support transparent transmission of serial completely,and achieve a plug and play serial

2、Support new AT+instruction set, Which is all based on ASCII format, it’s simple to use and pellucid.

3、Support more perfect TCP/IP protocol tack, support DHCP protocol for dynamicassignation of IP address and DNS domain name parsing.

4、Embed WEB server, and achieve the long-range parameters configuration through wireless network with IE browser.

5、Support more prefect transmission performance,the maximum sending rate can reach to 11KB/s.

Test

Here we supply a detailed test example. You can download the test file in the Download list. With Arduino WiFi Module Shield, this wifi module can easily compatable with Arduino.

First you should configure the wifi module. On your PC you should visit the admin panel of your wifi network. Usually this address is http://192.168.1.1



Connect wifi module with PC via USB-TTL module. Start wifi software to find the device. Input all the information needed to configure the wifi module.



Set the wifi IP address 192.168.1.119 in server mode. Port is 8089.

After the configuration on wifi module, upload the following code to Arduino:

void setup()
{
Serial.begin(115200);
}
void loop()
{
boolean currentLineIsBlank = true;
while(1){
if (Serial.available()) {
char c = Serial.read();
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == 'n' && currentLineIsBlank) {
// send the webpage
Serial.println("HTTP/1.1 200 OKrnContent-Type: text/htmlrnrn<center><h1>Hello World!! I am WiFi WebServer!!!</h1></center>");
break;

}
if (c == 'n') {
// you're starting a new line
currentLineIsBlank = true;
}
else if (c != 'r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
}


Connect WiFi module with Arduino

In your browser, visit http://192.168.1.119:8089




Arduino WiFi Module Shield




Finally here comes the WiFi shield for Arduino. We have UART WiFi Network Server/Client Module Kits. However, you have to connect wires by hand to Arduino. Now, with this module, you can get rid of the wires from your Arduino. Just plug in and play.


Interface

Besides the interface for wifi module, this shield has some other interface on it.

Port 1: the interface for UART WiFi Network Server/Client Module Kits. Please note the antenna direction is up.
 
Port 2: Here we use special designs to allow your wifi module switch communication with between Arduino or your PC. We made a mark to indication the plugging. In the picture above, wifi module can communication with Arduino.

Port 3: UART interface, considering this shield would be used in other cases, we extended UART interface from Arduino. The 4 pins above are: 3.3V, TX, RX, GND. The 4 pins below are 5V, TX, RX, GND. All the TX and RX are 5V TTL. But 5V TTL and 3.3V TTL are compatible. please note port 2 could determin the TX and RX pins. As the port 2 setting above in the picture, the pins of port 3 will be as the mark on the board. You can refer to the design document for more information

Port 4: I2C port of Arduino.

Port 5: The pins are 5V, digital pin7 on Arduino, digital pin6 on Arduino, GND. We place this port on board because some times we need to use soft-serial or soft-I2C to communicate.


If you want to know more information about this kit, please download and see the configuration step by step in the test file. You can download below.
