If you issue an RFCOMM write call, the data will be delivered unless the connection is terminated. Unless there are horrible radio conditions, it seems unlikely to take very long before the write completes and you callback is called. Are you having specific problems with writes taking too long to complete? In answer to your question, your best bet is probably to create an NSTimer with the timeout that you want. Then in your callback, yoou can invalidate the timer if it hasn't fired. With that model, there is no need to block your main thread. Either the timer will fire, or you will get your write callback called. I'm not sure if this is even possible or advisable (I've never used Cocoa threading...) Any ideas, including any timing guarantees made by Apple or Bluetooth or RFCOMM? My timing constraints tend to be "as real time as possible"... once again, is there a lower level api? ;-) This email sent to site_archiver@lists.apple.com
