I am currently coding flight instruments for the Stratux flight box in Codea.
The box talks on websockets via WiFi.
Is there any chance to listen to websockets (wss:/ …) in Codea?
The last post on this topic is some years old. My hope is that something improved…
I have a solution that works in coronalabs but I prefer Codea for coding!
@odo Codea has socket, is that the same as websockets. Codea also has osc which I think is easier than socket. I have code that transfers files or other info between iPads on the same network using osc.
Websockets is sockets plus a special protocol. There are lua websocket implementations i.e. on github. But these solutions need more required modules that I don’t find in Codea.
OSC: yes. I really like OSC and I wrote some sample code for me. But unfortunately the hardware that I am targeting (www.stratux.me) just doesn’t use OSC in its software stack. I uses websockets,
My goal is to read the data of the stratux box (or more precisely: react on the data that it pushes to me) and Display flight instruments in Codea. Attitude and Heading (artificial horizon) and air traffic display.
So unfortunately I need websockets
Ok. Trying to help myself until there is a better solution…
I started to port https://github.com/lipp/lua-websockets to Codea. I want to make it a Codea library.
But I a, am stuck now, because Codea doesn’t seem to have SSL included.
This line of code fails
require „ssl“
Does somebody know a solution for that problem?
As a workaround: Can I compile in Xcode including additional modules like ssl?
If this is the case, I would maybe not port websockets as a Codea library but link it together with ssl as Objective-C. Disadvantage would be, that I can‘t use it on the IPad in the development environment. Right? So I would have to use a mock WebSocket-client in Codea on the IPad but the AppStore Version (or the Xcode Version) would be able to use websockets including ssl. Am I right with this idea? I don‘t have so much Codea experience yet to fully understand the Xcode concept of Codea.
Basically, the idea is: if Codea doesn’t support websockets or ssl, I would wrap an Objective-C library like this one: https://github.com/zwopple/PocketSocket within XCode.
Does this approach make sense?
@odo I think iOS just added websocket support to its networking library, might be a good opportunity to include and design a Lua API around it for the runtime
https://developer.apple.com/documentation/foundation/nsurlsessionwebsockettask?language=objc
@Simeon that would be great!
@Simeon , yes, IOS added websocket support in swift,
I just tried some sample code. It is not the most intuitive way of implementing websockets but anyway 
Do you think that you will integrate the API in Codea?
And do you have an idea when it could be released?
I just started to implement my code for the flight instrument in Codea. And I really enjoy coding in Codea. But the websockets would be a dealbreaker for me because this is the only way for me to communicate with the aviation computer that sends the data to my app.
