File transfer not working

@ricardojlrufino Sorry for the late reply. What is the file type you tried to send?

[vj-abishek]

It looks like you are connected only to the voice channel. And not connected to the data channel.

Process to make a successful connection:

Peer 1 and peer 2 need to be in online.
And both need to be in same conversation page or chatting to enable file transfering. File transfer enabled automatically. When enabled the blue online dot will turn into purple dot. After that you can send unlimited files. And also if in the same network it works without using internet.

The only issue for now is the connection failure issue. I'm working it and will be resolved soon.
And also looking for a better solution for connection to establish. And make file transfering easy.

@vj-abishek Have you found a way for better conenction failure ? I'm curious what troubles did you encounter and how can I help to solve them.

Why the connection is failing?

• There can be multiple issues, everything is related to exchange of signalling data. The sender initiates the connection but the reciever is not ready yet etc. There should be a retry mechanism

What if the receiver is not available?

• Need to have a fallback method. If both the clients are available then the peer-to-peer data transfer mechanism can be used. If it is not available, need to have a fallback method such as uploading to a central server. Which makes the app more reliable.

What are the other solutions other than using simple-peer?

• Webtorrent API is a streaming torrent client for Node.js and the web. Of course, it uses simple-peer under the hood. However, the connection between two or more clients is handled by the web torrent itself. So it will be much more efficient and reliable.
