Finally got time to return to the Pi.<\/p>\n
Yes, the Raspberry Pi can talk to the SBrick. It’s only necessary to install Bluez 5.<\/p>\n
But as the standard Raspbian is based on Debian Wheezy, if you install bluez from the repositories<\/p>\n
sudo apt-get install bluez<\/pre>\nyou will get Bluez 4 (today, 1 December 2014, it’s version 4.99). I can make a Low Energy Scan (lescan) and find the SBrick but my gatttool commands fail with<\/p>\n
Host is down (112)<\/pre>\nSo we need Bluez 5. There are at least two ways:<\/p>\n
I’m lazy, I don’t like to compile anything. I’m also afraid that any update might brake compatibility and forces me to recompile again. And my laptop (Unbuntu) and my EV3 (ev3dev) are already running a version of Jessie so let’s update.<\/p>\n
Warning:<\/strong> Raspbian update from Wheezy to Jessie takes almost a day – so compiling Bluez might appeal to those in a hurry.<\/p>\n We need enough free space on the SD card. I used a 4 GB card and my first try failed miserable after a long night. So the second time I removed some things to assure an happy end.<\/p>\n First I transfered the most recent image available<\/a> (2014-09-09) to the 4 GB card and edited networking to get wi-fi (I only use SSH with the Raspberry, like I do with the LEGO Mindstorms EV3).<\/p>\n After first boot with the fresh card run rasp-config to expand the file system with all free space available.<\/p>\n after next boot remove some heavy things and clean:<\/p>\n there are now 2.0 GB available on the 4.0 GB card. That’s enough, let’s change the source of our packages:<\/p>\n replace ‘wheezy’ with ‘jessie’ and save.<\/p>\n Now we are already using a Debian Jessie version of Raspbian.<\/p>\n As of 1 December 2014, Debian Jessie for Raspberry Pi uses bluez 5.23-1. Now remove all garbage and check space again:<\/p>\n 807 MB avaliable, not bad.<\/p>\n My bluetooth BT 4.0 USB dongle is recognized (it already was) but is not active by default so before using it<\/p>\n now gatttool commands work with the SBrick, and so all my scripts from Ubuntu and EV3.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Finally got time to return to the Pi.
