Server not sending HTTP 101 response when creating a websocket using CC3000 and socket.io -

-

i connecting cc3000 node.js server using socket.io. have used following library create websocket https://github.com/chadstachowicz/socket_io_arduino_cc3000

in socketioclient.cpp, creates tcp connection, gets session-id(sid). disconnects , creates tcp connection , uses sid upgrade connection websocket. client(here cc3000) sends following header information:

client.print(f("get /socket.io/1/websocket/")); client.print(sid); client.println(f(" http/1.1")); client.print(f("host: ")); client.println(hostname); client.println(f("origin: arduinosocketioclient")); client.println(f("upgrade: websocket"));    // must camelcase ?! client.println(f("connection: upgrade\r\n"));

after request client waits http 101 response server. server not sending response. logs warning "websocket connection invalid" , ends connection.

is protocol creating websocket fine or there missing information in header?

also, want know should value of 'origin' be? during first handshake "arduino" whereas in second handshake "arduinosocketioclient".

you missing sec-websocket-key , sec-websocket-version headers, key part of websocket protocol handshake.

this how actual handshake looks:

get /chat http/1.1 host: server.example.com upgrade: websocket connection: upgrade sec-websocket-key: x3jjhmbdl1ezlkh9gbhxdw== sec-websocket-protocol: chat, superchat sec-websocket-version: 13 origin: http://example.com

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
