The suggestion was to use raw sockets to achieve it. I had found Scott Gifford's code using exactly that approach (in the archive). But my problem is: I always get EVT_INQUIRY_RESULT, not the desired EVT_INQUIRY_RESULT_WITH_RSSI. I check the "mode" value usingn "hci_read_inquiry_mode" which gave me 1. Is it correct? I don't know what mode should be set for Request_with_RSSI. Also, my hci_send_cmd looks like the following (copied from Scott's program): hci_send_cmd(dd, OGF_LINK_CTL, OCF_INQUIRY, INQUIRY_CP_SIZE, &cp); where cp.lap[2] = 0x9e cp.lap[1] = 0x8b cp.lap[0] = 0x33 I don't know what these values mean (I see exactly similar value for cp.lap in the hci_inquiry function from the bluez libraries). Could anyone give me any pointers to know more about them? Thanks Mahtab PS. My dongle and mobile phone both support "Request with RSSI" feature. --------------------------------- Yahoo!
