While searching for some info on BIO, I remember seeing an article showing how one could actually format (put some markers in) text data so that once the data is pushed via bluetooth, the receiving phone "displays" it as a SMS. Making it possible to "send" a SMS over bluetooth.

However I can't find the article anymore. So here are my questions...
Is it actually possible to what I described above??
If not has anybody tried to actually send a raw SMS PDU via BT and have it recognized by the phone as a SMS ?
Or are SMS only meant to be sent over GSM channels??

Thank you for your answers & time!
