Data channel file transfer
==========================
This example illustrates sending a file over a data channel using an
RTCPeerConnection and a "copy and paste" signaling channel to exchange SDP.
First install the required packages:
.. code-block:: console
$ pip install aiortc
On Linux and Mac OS X you can also install uvloop for better performance:
.. code-block:: console
$ pip install uvloop
To run the example, you will need instances of the `filexfer` example:
- The first takes on the role of the offerer. It generates an offer which you
must copy-and-paste to the answerer.
.. code-block:: console
$ python filexfer.py send somefile.pdf
- The second takes on the role of the answerer. When given an offer, it will
generate an answer which you must copy-and-paste to the offerer.
.. code-block:: console
$ python filexfer.py receive received.pdf
