Getting Started With Udoo Neo

This page describes how to get started with a Udoo Neo board running Ubuntu 14.04 (UDOObuntu 2), including support for Bluetooth LE and the TI SensorTag.

NOTE: As of 2015-12-21 Bluetooth LE does not seem to work with a SensorTag. While the SensorTag shows up in the scan (hcitool lescan), it's not possible to connect to it from the Neo. Same SensorTag works fine with a Raspberry Pi with external Bluetooth 4.0 dongle.

Prerequisites

$ sudo apt-get update
$ sudo apt-get install libssl-dev
$ sudo apt-get install bluetooth
$ sudo apt-get install build-essential libglib2.0-dev libdbus-1-dev

Building macchina.io

$ git clone https://github.com/macchina-io/macchina.io.git
$ cd macchina.io
$ make -s -j2 DEFAULT_TARGET=shared_release

Building bluepy (for bluepy-helper)

$ cd ..
$ git clone https://github.com/macchina-io/bluepy.git
$ cd bluepy/bluepy
$ make
$ sudo cp bluepy-helper /usr/local/bin/

Enabling Bluetooth

$ sudo hciconfig hci0 up

Search for a TI SensorTag

$  sudo hcitool lescan
LE Scan ...
C4:BE:84:72:C5:06 (unknown)
C4:BE:84:72:C5:06 CC2650 SensorTag
^C

Enable TI SensorTag in macchina.io Configuration

Edit macchina.io/server/macchina.properties and add the following lines:

#
# Bluetooth LE/SensorTag
#
btle.bluez.helper = /usr/local/bin/bluepy-helper
sensortag.sensors.1.address = C4:BE:84:72:C5:06

The SensorTag address must match the address discovered with sudo hcitool lescan.

Run macchina.io

$ cd macchina.io/server
$ bin/Linux/armv7l/macchina
