Instance Method Details

#recvfrom_nonblock(length, flags = 0) ⇒ Object

The reader thread writes each datagram into rsock followed by its sockaddr, so a recvfrom() pulls the data datagram then the sockaddr datagram back off the pair. Mirrors Datagram::SocketInterface.

def recvfrom_nonblock(length, flags = 0)
  data     = super(length, flags)[0]
  sockaddr = super(MAX_SOCKADDR_LENGTH, flags)[0]
  [data, sockaddr]
end

#send(buf, _flags = 0, _a = nil, _b = nil) ⇒ Object

UDPSocket#send-compatible signature. The modem connection is bound to a single peer (AT+QIOPEN “UDP”,“host”,port), so the explicit host/port are accepted to satisfy the interface but the datagram always goes to that peer.
