WiFi PLUS click is a compact solution for adding WiFi communication to your project. The click features MRF24WB0MA – 2.4GHz, IEEE std. 802.11 - compliant module from Microchip, as well as MCW1001 companion controller with on-board TCP/IP stack and 802.11 connection manager.

The combination of the MRF24WB0MA and MCW1001 results in support for IEEE Standard 802.11 and IP services.

WiFi PLUS click is designed to run on a 3.3V power supply. It communicates with the target MCU over an UART interface.

PCB antenna

The MRF24WB0MA RF transceiver module contains integrated PCB antenna with range up to 400m.

MRF24WB0MA module

MRF24WB0MA is a low-power, 2.4 GHz, IEEE 802.11-compliant, surface mount module with all associated RF components such as crystal oscillator, bypass and bias passives with integrated MAC, baseband, RF and power amplifier, and built-in hardware support for AES, and TKIP (WEP, WPA, WPA2 security).

The module has low power consumption modes. In sleep mode it uses 250 µA (typical), and while in hibernate mode the typical power consumption is only 0.1 µA.

MCW1001A companion chip

The MCW1001A is a companion chip to the MRF24WB0 802.11 module. It provides simple socket based method of sending and receiving data from the MRF24WB0 802.11 module. The MCW1001A has an on-board TCP/IP stack and 802.11 connection manager to simplify the connection between a wireless network and the TCP/IP stack management.

Programming

The following function handles the UDP packet recieved from a wireless client.

01: void UDP_Handler()
02: {
03: int i;
04: unsigned short cnt;
05: response = Net_Wireless_MCW1001_SocketCreate( &socketHandle, _NET_WIRELESS_MCW1001_SOCKET_TYPE_UDP );
06: if( response == _NET_WIRELESS_MCW1001_NO_ERROR )
07: {
08: LCD_ClrLine(2);
09: Lcd_Out(2, 1, "Socket is OK");
10: Delay_ms(600);
11: }
12: Net_Wireless_MCW1001_SocketBind( socketHandle, &localPort, &bindResult );
13: if( bindResult < 254 )
14: {
15: LCD_ClrLine( 2 );
16: Lcd_Out( 2, 1, "Bind is OK" );
17: Delay_ms( 600 );
18: }
19: Net_Wireless_MCW1001_TimeToWait = 5;
20: response = Net_Wireless_MCW1001_UDP_SendBytes( socketHandle, remotePort, remoteIP, dat, strlen( dat ), &cntBytes );

36: Lcd_Chr( 1, 16, ' ' );
37: dat[ cntBytes ] = 0;

39: else

41: Lcd_Chr( 1, 16, '!' ); // Exlamation indicates ON LCD that recived data is too long for LCD line
42: dat[ 16 ] = 0; // Sting will be limited to 16 characters - adding zero teminaging character
43: }
