If you try unplugging it and re-plugging it in does that fix it? –Tim Tisdall Mar 6 '14 at 14:29 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote accepted First off, I spoke with a colleague about my configuration and for Raspbian (or more specifically, Debian) he recommended the following configuration settings: ./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --enable-library --with-systemdsystemunitdir=/lib/systemd/system --with-systemduserunitdir=/usr/lib/systemd Afterward, upon further inspection, here is how I was able to successfully connect.

The command prints out Set scan parameters failed: Input/output error. I'm not sure, what exactly happens here. My iPhone is advertising here. I'm using a BLE dongle from IOGear. However, if I restart my machine, it shows the a MAC address after I issue the lescan command, and starts showing the same error after I issue input output error the lescan command a couple of more times. Is it like, the lescan command cannot be issued more than once? raspberry-pi bluetooth-lowenergy bluez share|improve this question edited Apr 14 '14 at 16:45 yousif saeed 2,26611435 asked Feb 27 '14 at 7:38 aauser 3261513 try unplugging it and re-plugging it in. There's all sorts of ways the dongles can get into states where they don't respond the way you want. The IOGear one seems to be the best, though. –Tim Tisdall Feb 27 '14 at 20:02 @aauser - did you ever solve this? I'm stuck on the same problem. –Duncan Bayne Mar 10 '14 at 2:14 @aauser - I should mention that I'm using a D-Link DBT-120 on 64-bit Linux Mint 16 (Petra). –Duncan Bayne Mar 10 '14 at 4:32 1 It appears the BlueZ BLE scanning is still pretty buggy. However, this thread might help: redbearlab.zendesk.com/entries/… –David H. Bennett Mar 17 '14 at 0:20 1 Also, what is your kernel and BlueZ versions? The end of this thread mentions kernel 3.5 or greater. linkedin.com/groups/… –David H. Bennett Mar 17 '14 at 0:23 | show 2 more comments 3 Answers 3 active oldest votes up vote 17
