Introduction

USR-WIFI232-B2 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 280m with 3dbi antenna. 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.
