Embedded Devices work !

I just cant stop now. I am so on top!!!

Services show up!

I just spent 4 hours fixing stuff (these socket address byte ordering can be a bitch!) and now I have services being properly advertised using SCPD (althoug it’s reading from the xml still, not using the actual service class internal data) !!

I am on a roll !

Ok today has been very productive (10 hours of work !): My device shows up in DeviceSpy !! Here’s what I have done today:
– http server listens on each interface
– sends the description doc on each interface
– sends a byebye before advertisement
– sends a byebye on quit
– fixed many issues with sockets and streams

2 words: IT ROCKS !

Tomorrow, I am working on parsing a description doc xml and create the structure, then the SCPD for the services and Description layer of UPnP is done !

Ok I am beat, it’s 5am. I am insane to work on the week-end and so late. Tomorrow I got to spend time with K.

If I can get this done by CES, that would rock. I need to find an ipaq next week….

XML Parser working!

XML Parser working! 5 hours of work and 20KB later, I have a nice little parser. Thanks to bro (Cho,Kyung Min) and his xmlite. I removed all MFC references as well as std osstream which take more space. I need to remove the vector next to be even more compact…

Scheduler works!

After spending 2 nights (at least 10 hours total), I have come up with a very very nice solution to my problem of multiplexing sockets and threads. I have made a Scheduler that accepts tasks and perform the tasks in a thread. The tasks must be non blocking of course and yield. So far the ssdp announce and listen can be non blocking and it works! I created 2 tasks. One to announce and one to listen with only one thread!. I now receive my announcements, even though I have only one thread! Ok I dont want to receive my announcements but at least it works! Now I just need to add tasks to listen to incoming requests on my webserver (for each interface) and we have a very basic upnp support with only 1 thread!!!! Ah I love it I love it …

Back to C++ ! (5h)

No way I was going to continue the C route. The overhead is too painful. I am back to good old OOP. Finished rewriting the socket and http classes today. I started working on Ssdp messages (Search, Notify and Response) to realize that they are just HTTP requests and responses. The only thing I noticed is that being sent over UDP, the parsing is different. It needs to read the whole datagram and not 1 byte at a time, otherwise it fails. I need to figure out a clean way to abstract that …
