Product introduction:

  • Since the Arduino serial port buffer is only 128 bytes, when the http request and the website interact, the length of the http header is usually greater than 128 bytes, which causes content coverage, such as http response: head+body has 200 bytes, arduino only Can receive 128 bytes.
  • Based on this, we implemented the http proxy in the firmware layer. More powerfully, this firmware supports the Airkiss configuration online, does not connect to the hotspot, and then configures through the webpage.

Arduino only calls:

  • GET request:
  1. Name: do_get(url,header);
  2. Parameter 1: url: the requested url address
  3. Parameter 2: header: the header information of the request, the default is empty. If you need to customize the header, the format is separated by ' ' for each header unit, such as "API_KEY:key API_USER:doit"
  4. Returns: the body information returned as http
  • POST request:
  1. Name: do_post(url,q_str,header);;
  2. Parameter 1: url: the requested url address
  3. Parameter 2: q_str: the body of the request, such as key=value
  4. Parameter 3: header: the header information of the request, the default is empty. If you need to customize the header, the format is separated by ' ' for each header unit, such as "API_KEY:key API_USER:doit"
  5. Returns: the body information returned as http
  • PUT request:
  1. Name: do_put(url,q_str,header);;
  2. Parameter 1: url: the requested url address
  3. Parameter 2: q_str: the body of the request, such as key=value
  4. Parameter 3: header: the header information of the request, the default is empty. If you need to customize the header, the format is separated by ' ' for each header unit, such as "API_KEY:key API_USER:doit"
  5. Returns: the body information returned as http
  • DELETE request:
  1. Name: do_delete(url,q_str,header);;
  2. Parameter 1: url: the requested url address
  3. Parameter 2: q_str: the body of the request, such as key=value
  4. Parameter 3: header: the header information of the request, the default is empty. If you need to customize the header, the format is separated by ' ' for each header unit, such as "API_KEY:key API_USER:doit"
  5. Returns: the body information returned as http

Features:

  • WiFi uses industrial grade chip ESP8266, the module is ESP-13 with metal shield, strong anti-interference ability;
  • The standard pins are compatible with the main control board such as Arduino Uno and Mega2560. The Arduino and UNO are connected with a voltage conversion chip, making 3.3V and 5V compatible.
  • The serial port is controlled by a dual-dial switch, so that the expansion board can be used as an Arduino Uno expansion board alone or as an ESP8266 expansion board.
  • Real serial WiFi, Arduino program does not require any configuration;
  • Configure WiFi parameters and serial port parameters based on Web Server;
  • Can be used as a stand-alone ESP8266 development board, download official AT command firmware, NodeMCU open source firmware, etc.
  • Can be used as a stand-alone Arduino Uno expansion board with all pins.

Technical specifications:

  • Support for wireless 802.11 b/g/n standards;
  • Support STA/AP working modes;
  • Built-in TCP/IP protocol stack, you can configure a socket;
  • Support standard TCP/UDP Server and Client;
  • Serial port baud rate support: 1200/2400/4800/9600/19200/38400/57600/74800/115200 bps;
  • Serial data bit: 5/6/7/8 bit;
  • Serial port parity: none;
  • Serial port stop bit: 1/2 bit;
  • Standard Arduino UNO, Mega pin spacing;
  • Leading to Arduino Pin 2/3/4/5/6/7/8/9/10/11/12/13;
