I have successfully changed the inquiry mode to be 0x01 and sent out the inquiry. I can see from the "Hci dump" that it is working, I can see the inquiry result with RSSI values. However, My problem is how can I get(/keep) those rssi values so that I can use them later on.I know there is a struct "inquiry_info_with_rssi", but what should I assign to this to get the response value.Please give me some hint so that I could move on. Your kindness is greatly appreciated.Below is my code.//Set up an event filter looking after the inquiry related events struct hci_filter InqFilter; hci_filter_clear(&InqFilter); hci_filter_set_ptype(HCI_EVENT_PKT, &InqFilter); hci_filter_set_event(EVT_INQUIRY_RESULT, &InqFilter); hci_filter_set_event(EVT_INQUIRY_RESULT_WITH_RSSI, &InqFilter); hci_filter_set_event(EVT_INQUIRY_COMPLETE, &InqFilter); if (setsockopt(sock, SOL_HCI, HCI_FILTER , &InqFilter, sizeof(InqFilter)) < 0) { perror("Fail to setup filter!"); exit(1); } //***************************************************** //inquiry with the RSSI result inquiry_info_with_rssi read_rssi; //Note **I try to define this struct variable here, but not sure what to assign to it. write_inquiry_mode_cp cpp; cpp.mode = 0x01; //set inquiry mode int set_Inquiring = hci_send_cmd(sock, OGF_HOST_CTL, OCF_WRITE_INQUIRY_MODE, WRITE_INQUIRY_MODE_RP_SIZE, &cpp); inquiry_cp cp; cp.lap[0] =0x33; cp.lap[1] =0x8b; cp.lap[2] =0x9e; cp.length = 4; //=4*1.28second = 5seconds cp.num_rsp =0; //do inquiry int Inquiring = hci_send_cmd(sock, OGF_LINK_CTL,OCF_INQUIRY , INQUIRY_CP_SIZE, &cp); if (Inquiring < 0) { printf("starting to inquire: %d\n",Inquiring); exit(1); } else printf ("Done inquiry with RSSI!\n"); printf("rssi value = %d \n", read_rssi.rssi); close( sock );//close socket//***************************************************** Best regards,Newbie _________________________________________________________________ If you like crossword puzzles, then you'll love Flexicon, a game which combines four overlapping crossword puzzles into one! http://g.msn.ca/ca55/208 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bluez-users mailing list Bluez-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bluez-users
