I'm really struggling to get this working. I have two issues.
1. broadcast messages don't arrive.
2. recv() hangs until there is some data available because I can't see how
to apply a timeout.
I decided to just try to talk to myself as a first step. Could someone else
try this please and tell me if I'm doing something wrong or if broadcast is
broken.
Sender side:
*This works*
#addr = IPv4(255,255,255,255)
addr = IPv4(127,0,0,1)
s = UdpSocket()
#ccall(:uv_udp_set_broadcast,Cint,(Ptr{Void},Cint), s, 1)
msg = zeros(Uint8, 63)
msg[1] = 0xef
msg[2] = 0xfe
msg[3] = 0x02
send(s, addr, 1024, msg)
*This fails (nothing received)*
addr = IPv4(255,255,255,255)
#addr = IPv4(127,0,0,1)
s = UdpSocket()
ccall(:uv_udp_set_broadcast,Cint,(Ptr{Void},Cint), s, 1)
msg = zeros(Uint8, 63)
msg[1] = 0xef
msg[2] = 0xfe
msg[3] = 0x02
send(s, addr, 1024, msg)
Receiver side:
addr = IPv4(127,0,0,1)
s = UdpSocket()
bind(s, addr, 1024)
println(recv(s))
