You'll use OBEX to send files to the phone. You don't need any AT commands to do that. There are several examples in /Developer/Examples/Bluetooth. For SMS you'll need a few things. First, find the AT Commands manual for the T68i on Ericsson's site (or the T68, T39, R520. They're all pretty much the same). The commands for sending and receiving SMS are pretty simple (setup notifications for incoming messages, send messages). It's encoding and decoding the PDU string that's a little more tricky. Here's a good site for the PDU format: http://www.dreamfabric.com/sms/ You'll also want to pick up the actual GSM spec from www.etsi.org (documents GSM 03.40 and GSM 03.38) to fill in any other details. Here's a sample PDU string to try once you get things working: 07919170389103F1040B919161177708F000002080820154518A53CE37886A0585DD6490 FB0D1297CB72503BBC2E8390EF76590E3ABF41F377BB4C47A7DD67D0FCDD2ED3D169F7D9 053ABE414379589FFF81886FF7890E6AA7DD6450DA0C4A82C8EF1008 Good luck!

Specifically the ability to send an SMS and also how Addressbook gets the SMS upon receipt from the phone. Does one have to be intimately familiar with the AT command set for the phone in order to be able to do the above? _______________________________________________ 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.
