The BSD sockets are one of the marvels hidden the Galileo's hood, they are extremely powerful (they are true Linux sockets!) and they will make you forget very quickly the numerous limitations (and bugs.) of the W5100 chip. You can easily access to the Galileo's embedded network support (the local RJ45 if you prefer) from any sketch simply by using the BSD sockets. The shield is perfect for AVR based Arduino boards, but using it on Galileo is exactly like if you have a Tesla car and you want to move it using an electric bicycle motor using the car batteries If you are using the W5100 shield on the Galileo, simply forget about it Question : are you using the Ethernet shield or the embedded network socket on the Galileo ? I am a bit late to answer to this question, but I think it can be interesting. I am having a lot of fun with my Galileo even though it does not work as I expect it to. You'll be able to see exactly why your commands or scripts do not work. Log into the linux environment over SSH (Putty anybody?), and copy and paste your commands into the console and run them. to configure the ethernet port first, and then try sending packets using a compatible broadcast address, like in this case it would be '10.0.21.255'.Ī tip I figured out on my own for working with 'system()' commands in C++ just btw: So just for the heck of it, I want to try something else out tonight to see if I can still get UDP communication to work, and I'll report back to the community here when I get a chance. I couldn't get any packets to send over UDP, so I installed Linux on my Galileo on an SD card as per Intel's instructions, and then I launched a Python script from the C++ interface and the Python script took care of everything much more easily. Udp.write(packetBuffer, WOL_PACKET_SIZE) memset(packetBuffer, 0, NTP_PACKET_SIZE) Unsigned long sendWOLpacket(unsigned char macaddr ) Static unsigned char wake_mac = // broadcast IP address Package etherconn is a golang pkg that allow user to send/receive Ethernet payload (like IP pkt) or UDP packet ,with custom Ethernet encapsulation like MAC.

This is modified from some code in the NTP Time example that I kept running into online while looking for UDP-related info. In many cases while using an Arduino, you will want to see the data being. The key part being where the packet get sent in the sendWOLpacket routine. So here's my code below for the 'Lite' version of my WOL Application.
