Right, I meant udp-lc bridge. I am using flex 3.2 sdk and flash 10. since I am using Flex Builder 3.0, I cannot move to flex4sdk as you suggested

By udp + tuio bridge I guess you mean the udp-lc bridge. If yes than yes this is a known problem which is result of hijacking the localconnection which’s functionality is just reverse engineered and sometimes it happens that flash doesn’t close the old shared memory file so the bridge thinks that flash still reads from this memory file although it already opened another one.
Which version of flex are you using? In the flex4sdk beta and flash 10 this behaviour is less frequent or even next to zero.

Thanks for your reply and help. The reason I tried TCP binary option is because UDP + TUIO bridge does not work well for me. In fact, when stopping “abruptly” my application (e.g. stop debug from IDE flex), the communication is broken somewhere. I have to restart both my bridge and my application. Have you already noticed that?

Hi, that is because ccv seems to have chosen a different way to send raw tracking data via TCP than the one used in the TCPConnector.~~I’ll try to add support to the svn revision asap.~~

edit: I just had a closer look at ccv’s “binary tcp” mode and it looks like it doesn’t use TUIO at all to send the tracking data. So I don’t know if I will support this in the near future since this library is all about TUIO formatted tracking data :/

I am currently using the last CCV 1.3 version and TUIO library AS3 0.6. is it possible to use “Communication TCP BINARY” option in CCV and how? Because it looks as I am receiving some packets data but the parsing probably fails and I do not have any TUIO event received in my flash application?
my TUIO initialization is as follows

…
this._tuioClient = new TuioClient(new TCPConnector(“127.0.0.1″,3000));
this._tuioManager = new TuioManager(this.stage, this._tuioClient);
…

so, what’s wrong?
thanks

Thanks for the testing. I guess I’ll have to buy a iPod Touch at last even if it just for MSARemote xD
What could be the problem is that if the send rate of the MSARemote is higher than the shared memory read rate of flash so packets tend to get lost because the udp-lc-bridge does no buffering.
I am relieved that it works well with the tongseng tracker
And on the opening the swf twice: the LCConnector automatically checks if the connection name is already in use and appends a digit to the name if needed

I just swapped to tongseng tracker and my apple mighty mouse for input – it runs like a charm. So the problem is somewhere in between MSARemote and the udp-bridge.

Hi gimmix,

the response is chopy, it is interuppted by lags. Also strange: The localConnection does not throw any errors when I open the swf twice (which is expected). Can this be caused by the way the localConnection is hacked?

The performance is bad for single and multi point inputs…

Maybe you could try if the performance is better if you use the UDPConnector included in the current svn revision. You’ll need the air2beta2 sdk though which you can get for free at labs.adobe.com
Does a single point only perform any better than multiple points? Is the response choppy or is it sirupy (if that even is a word xD)
