The LG Voyager supports...
- Bluetooth Object Push (aka OPP) for vCard/Contacts and Calendar items
- Bluetooth OBEX File Transfers (aka FTP) limited to User Generated Content Only (MY_PIX, MY_SOUNDS, MY_VIDEO but not ring tones/music)
(for the difference between OPP and FTP see -> http://mark.cdmaforums.com/FTPOPP.htm )
I can tell you that I've tried OPP for sending pictures from the Voyager to my Blackberry... And from the Voyager to my PC... each time results in an error pop-up on the Voyager's screen saying "Not supported by receiving device". Trying OPP for Sending a picture from my Blackberry to the Voyager... also results in a pop-up on the Voyager's screen saying.... "Not supported by receiving device".
BUT OPP for sending a picture from my blackberry to my PC works just fine.
Obex FTP between my PC and Voyager works just as expected.
Opp for Contacts and Calendar should work no problem. I have transfered both, in BOTH directions between my Voyager and PC (with Outlook). I have transfered contacts between the Voyager and enV via Bluetooth. But I haven't tried Calendar between Voyager and enV.
For how I transfered contacts between the enV and Voyager.. see -> http://mark.cdmaforums.com/VX10K.htm
