I was trying to extend what the test/test-discovery script is doing, but it seems using DBus I can only get notified of new devices being discovered.

However, I’d also like to get the RSSI - is it possible from that method? I have access to the open device (dd), and the evt_le_meta_event and le_advertising_info structures - but that doesn’t seem to be enough. There is a hci_read_rssi in lib/hci.c, but it requires a “handle” - I think it’s only useable if a conneciton is open. Actually, looking at the whole data received from the socket, I think the last byte - and the only byte remaining after the advertisement packet - is the RSSI. So I guess writing to the group worked as a rubber duck :) Adam -- Adam Warski http://twitter.com/#!/adamwarski http://www.softwaremill.com http://www.warski.org -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
