That is really a shame if it is not possible to send SMS via OBEX. I have used the last few days to study OBEX, and I really liked it. And there is really good support for OBEX in the IOBluetooth.framework. So when should I then use OBEX for? Is it only good for exchanging vCards with mobiles? I studied the "Specification for Ir Mobile Communications (IrMC)", and there is a chapter "9. Messaging" that I thought was applicable for SMS. The chapter is of course rather vague as all such specs are regarding to what it means about Messaging, it could as well be referring to emails. The chapter gives an example of how to construct a message object: BEGIN VMSG VERSION:1.0 BEGIN:VCARD VERSION:2.1 ... I used that as an example, but my T68i ignored it. Well, I should start studying the RFCOMM specs then. I feel like falling back to the early days of the PC revolution, where UART's and serial ports were the way of communicating with other computers.

The default way (older..) is to open an RFCOMM connection and send the appropriate AT commands every modem & cell phone do support. find the at command set description and examples on sending SMS on the net. matthias ringwald _______________________________________________ bluetooth-dev mailing list | bluetooth-dev@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.
