Re: [Discuss-gnuradio] How to "kill flowgraph" with a custom block

[davidk]

Dear Marcus, Happy new year!

Here is my UDP Server Block Python Code:

/import numpy
import socket
from gnuradio import gr
from gnuradio import blocks

UDP_IP = "192.168.10.2"
UDP_PORT = 58

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

class serverSource(gr.sync_block):
    def __init__(self):
       
gr.sync_block.__init__(self,name="serverSource",in_sig=None,out_sig=[numpy.float32])
        print "Setting up server"
        sock.bind((UDP_IP, UDP_PORT))

    def work(self, input_items, output_items):
        out = output_items[0]
        data, addr = sock.recvfrom(1024)
        packetString = repr(data)

        packetString = packetString.replace('\\x00','')
        packetString = packetString.replace('\'','')

        print "message received: ", packetString
        print "address: ", addr

        if packetString == 'stop':
            return -1

        return len(output_items[0])/

and here is my UDP Broadcast block:

/import numpy
import socket
from gnuradio import gr

class udpBroadcast(gr.basic_block):
    def __init__(self, ip, port, message):
       
gr.basic_block.__init__(self,name="udpBroadcast",in_sig=[numpy.float32],out_sig=[numpy.float32])
        print "Setting up UDP Message"

        UDP_IP = ip
        UDP_PORT = port
        MESSAGE = message

        sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))/

Hopefully you can make out what I'm aiming for here.

Many thanks
David
