Cross-platform socket API for Xamarin iOS/Android/Forms, Xamarin.Mac/MonoMac, Windows Phone 8/8.1, Windows Store and Windows Desktop.
Thanks for your help!
var client = new TcpSocketClient();
await client.ConnectAsync("127.0.0.1", 7812);
await client.ConnectAsync("127.0.0.1", 7812);
on Android device it doesn't work
on windows it is working
same pcl package
any idea?
in the same project project.windows is able to connect but project.droid not
I have a question to the UdpSocketMulticastClient
I am fairly new to the topic, so sorry for asking stupid questions.
When I fetch all nt interfaces using the CommsInterface.GetAllInterfacesAsync(), and provide this info to the UdpSocketMulticastClient.JoinMulticastGroupAsync() with the interfaces broadcast address, port = 50002, and the interface itself I always receive the following error
The parameter is incorrect. 'host': This is not a valid multicast address.
Address provided for example is 10.5.2.255. Any ideas?
THX
@ChristophvanderFecht sorry for the late reply, multicast must be done over a specific range of valid multicast addresses, i think
224.0.0.0 to 239.255.255.255 per https://en.wikipedia.org/wiki/Multicast_address
Quick Question:
Can we use it to connect iOS and Android devices together with this plugin?
I am using 2.0.2 version and UDPSocket Client
For file transfer I would strongly recommend using a TCP socket in any case
I am trying to send zip file of 148 kB approx
In case it helps you could check the TCP samples here https://github.com/rdavisau/sockets-for-pcl/tree/dev/Sockets/linqpad-samples/Tcp . They are linqpad queries but you can just look at them and maybe it will highlight something that's missing. You could check the TcpSocketClient.linq and TcpSocketListener.linq files as examples of how the sender and receiver could work
(though looking at them now I would recommend a larger buffer size)
I would like to ask one more question - Do you have discovery functionality support in your plugin. Actually I would like to discover the devices which connect on same network
please let me know, if socket-for-pcl plugin supports such functionality
for discovery, you can use udp sockets - each device listens with a udp on a specified port (not the one you use for your TCP operations).. to find these devices, the searching device sends a UDP broadcast message (255.255.255.255) to that port - and when the listeners respond you will get their addresses (they could also send back other details like their names, etc.)
but you might be able to find a library that can do this for you..
Apple Bonjour API for discovery
Hi @rdavisau - I am using rda-socket library > UdpSocketMulticastClient to discover all the devices available in my network. Using the UdpSocketMulticastClient lib I am able to receive the broadcast message. Now i want to send the acknowledgement to sender who initiated broadcasting, Can you guide me which method I can use to send acknowledgement after receiving the multicast message
hi @vivu12585_twitter - I'd have the broadcaster also run a listener (either udp or tcp depending on how you want the two parties to interact), then the party that is responding to the broadcast can send/connect to that. if the listen port needs to be dynamic, the broadcaster can send that information as part of it's broadcast message. you can get the details about the broadcaster from the message received event arguments
@tuanphamblogic you can try try wrapper: https://gist.github.com/rdavisau/7b466c855118a00c901a though i haven't used it in a long time
from memory it's actually difficult to reliably know whether the socket is connected using any properties on the socket (e.g. some discussion here https://stackoverflow.com/questions/2661764/how-to-check-if-a-socket-is-connected-disconnected-in-c). The general advice I took from that is that you need to try reading to truly know whether you are still connected, which is what the
BetterTcpSocketClient does in the above example. You could add an IsConnected property to BetterTcpSocketClient and update it based on the Connected/Disconnected events
Hello, I am new to the entire connection using UDP and TCP. It is required for a project of mine and just looking at your github repo, I am lost on what the functions really do. I am lost on the entire port thing as well, yes I am that new. I would like to know if you recommend anything as a beginner, to start understanding how to use your plugin properly ? Thanks for the advice in advance
