BT push (OPP)? Nuh-uh. Gotta implement HID profile. There's such a project for the N8x0 to play "I am a keyboard" for phones or computers, but I don't know of one for phones. And I doubt you can implement BT profiles from within javaME. Alternative (weaker) sol'n is to use SPP, and use the N8x0 hacks available for the various BT keyboards that are SPP rather than HID. Reasonable chance SPP is available, though I'm not real sure. AVRCP could work too, and I know some phones support that (with no add'l software on the phone). That would require implementation on the N8x0, I think. This would be particularly good if you're after a media control application... What DO you want this for, anyway? I'd think the N810's keyboard would be better. Unless, of course, you're using a 1980s brick-of-a-phone, with keys that came off an old Kaypro keyboard.
