@Legion:

Can you unzip the file ConsoleApp1.zip and run the command:

mono ./ConsoleApp1.exe

Note: No need the root privileges e.g. sudo

Please post the output.

=== AddressList ==== Af=[InterNetwork] Addr=[192.168.1.178] === Send Udp Message ==== Send Udp message=[EZ-B||Testing||192.168.1.178||23]

@DJ: It seems is a bug in the udp code:

please change your code:

        private void doSendUDP(string str)
        {
            using (UdpClient udpClient = new UdpClient("255.255.255.255", 4242))
            {
                byte[] bytes = Encoding.ASCII.GetBytes(str);
                udpClient.Send(bytes, bytes.Length);
            }
        }

to this code:

        private void doSendUDP(string str)
        {
            var ipEndPoint = new IPEndPoint(IPAddress.Broadcast, 4242);
            using (var udpClient = new UdpClient())
            {
                var bytes = Encoding.ASCII.GetBytes(str);
                udpClient.Send(bytes, bytes.Length, ipEndPoint);
                udpClient.Close();
            }
        }

Download this fix EZBPi_fixed.zip do backup copy of the existent EZBPI.exe and then override with the new file. then run:

sudo mono ./EZBPi.exe

Let me know if it works.

IT WORKED!!!!

Oh ty ty ty so much!

I’ll get amin to update next week. Thanks guys!!

Hi, I'm having the same problem as above on my RasPi3B when trying to run EZBPi.exe. I've followed all the above checks and the code update but I'm still getting the same response:

pi@raspberrypi:~ $ sudo mono /home/pi/EZBPi/EZBPi.exe Raspberry EZBPi Version: 2019.3.29.0 Verbose logging is: False Serial port is: /dev/serial0 EZB: TCP Started on port 23 EZ-B Server started on TCP Port: 23 Camera: TCP Started on port 24 Camera Server started on TCP Port: 24 Press ESC to quit Broadcast error. The broadcast service has stopped. Here is why: System.Net.Sockets.SocketException (0x80004005): Access denied at System.Net.Sockets.UdpClient.Connect (System.String hostname, System.Int32 port) [0x001b0] in :0 at System.Net.Sockets.UdpClient..ctor (System.String hostname, System.Int32 port) [0x00044] in :0 at EZBPi.Broadcaster.doSendUDP (System.String str) [0x00001] in <0d7091e22ba140df8312a9ba44fa579a>:0 at EZBPi.Broadcaster._timer_Elapsed (System.Object sender, System.Timers.ElapsedEventArgs e) [0x00050] in <0d7091e22ba140df8312a9ba44fa579a>:0

I also have a Pi ZeroW and a Pi 2B on the network and get the same response. Pi Zero and 3 both running Buster, Pi 2 running Stretch.

I've also tried all the other usual fixes, like disabling firewall etc.

I'm getting a similar response when trying to connect ARC 2019.05.08.00 from my PC (Win10) to the Pi:

Attempting connection on 192.168.1.183 Connection Failed: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 192.168.1.183:23 at System.Net.Sockets.Socket.InternalEndConnect(IAsyncResult asyncResult) at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult) at System.Net.Sockets.TcpClient.EndConnect(IAsyncResult asyncResult) at EZ_B.EZB.Connect(String hostname, Int32 baudRate) Disconnected

I don't have anything else running that might be causing any conflict and I can connect to all my Pi's remotely from my phone using RasPi Check and RaspController.

Regards, CRW

Did you use the exe fix PTP gave?
