Enabling SO_BROADCAST on a BeagleBone Black UDP socket to reach an entire LAN subnet, then proving delivery with a Wireshark capture on a separate Windows PC.
Read More →
Building a UDP echo server and client in C with socket(), bind(), sendto(), and recvfrom() on the BeagleBone Black â the smallest working example of the Berkeley sockets API, and what actually happens (and doesn't) when a UDP packet leaves the kernel.
