Introduction

USR-WIFI232-A2 is an embedded 802.11 b/g/n wifi /wireless module used for Transparent data transmission between MCU controlled device and wireless network.  Under open horizon and no obstacle situation,the Max transmission distance is 200m . In AP mode, the max Station connection is 32.

Feature

  • UART/GPIO/Ethernet data interface.
  • Built in Web Server/Webpage for configuration.
  • Webpage socket to Serial.
  • HTTP Client: send data as HTTP format automatically. Serial data submitted to server by HTTP (GET/POST).
  • DHCP: automatically obtain an IP address and query IP address.
  • DNS address and MAC address can be modified.
  • Synchronous and adaptive serial port baud rate.
  • Support router/bridge mode networking.
  • Registration packet: identified header can be added to packets to check
  • connection status.
  • Heartbeat packet: can be sent to serial or network periodic. To ensure connection is reliable, put an end to dead link.
  • Support UDP, TCP, HTTP protocol and Transparent transmission, AT Command Mode, HTTP Client Mode.

WIFI Networking Mode

1)AP: the wireless access point and the founder of wireless network. all devices can connect AP. E.g.: A router also work as AP.
In AP Mode, the Max STA connection is 32.
2)STA: terminal of the wireless network. All communication between STAs is through AP. e.g.: PC can work as STA.
3)AP+STA: supports one device as AT and one device as STA.

TCP/UDP Transparent Transmission Mode

Serial RS232 WIFI Converter WIFI232-602 work as TCP Client, TCP Server, UDP Client,
UDP Server Mode.
1) In TCP Client Mode: Client connects Server automatically. User should configure the TCP Server’s IP address and Port.
2) In TCP Server Mode: The Max Client number is 32.
3) In UDP Client Mode: serial data will be sent to a fix IP address/port which you appointed.
4) In UDP Server Mode: serial data will be sent to last source IP/Port.
