This is a demo for the WiflyInterface Library.
Dependencies: WiflyInterface mbed
Wifly Firmware Update
Part of the demo will use the software update API to install 1 of 2 versions of the Wifly firmware, from the Microchip web site. You can see in the demo below the commands to install each of the 2 versions.
WiflyInterface - Broadcast packet
Part of the demo will send a broadcast packet to the network.
// TeraTerm monitoring mbed | Windows network monitor // Initializing network interface... | > ReceiveUDP 40000 // Connecting to network... | Receiving datagrams... // Ethernet connected as 192.168.1.188 | // Ethernet MAC is 00:06:66:71:5d:ef | // Connected at 24 Mb/s | // Wifly info: wifly-EZX Ver: 4.75 Build: r1777, | // Oct 2 2015 10:18:50 on RN-171 | // | // ctrl-a to download Wifly firmward v4.41 | // ctrl-b to download Wifly firmward v4.75 | // ctrl-c to send a broadcast message | // | // User types ctrl-c in TeraTerm | // Broadcast sending 'Hello World' on port 40000 | Rx[10.789]: Hello World // done. | // User types ctrl-c in TeraTerm | // Broadcast sending 'Hello World' on port 40000 | Rx[13.673]: Hello World // done. |
