How to install & execute

Os and core components

Manual installation of initial components and prerequesites

• Installs Ubuntu OS on a Raspberry PI

https://ubuntu-mate.org/raspberry-pi/

• Boot PI and update packages:

sudo apt-get update

sudo apt-get dist-upgrade

• Install java 7 (if LLRPReader is needed)

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

• Install nodejs 5.x by adding this repository 'deb https://deb.nodesource.com/node_5.x xenial main' with:

curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -

and then:

sudo apt-get install -y nodejs

• Installs and configures Bluetooth core libraries

sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev

• Allow nodejs program to bind to ports under 1024 (required by snmp related plugin):

sudo setcap 'cap_net_bind_service=+ep' /usr/bin/nodejs

• Allow nodejs to read from bluetooth devices (require by bluetooth related plugins):

sudo setcap 'cap_net_raw+eip' /usr/bin/nodejs

• Allow non-privileged users (belonging to gpio group) to run GPIO commands:

git clone git://github.com/quick2wire/quick2wire-gpio-admin.git

cd quick2wire-gpio-admin

make

sudo make install

M2MBridge installation

• Install git:

sudo apt-get install git

• Clone git repository (https://github.com/AMTechMX/M2MBridge.git)

git clone https://github.com/AMTechMX/M2MBridge.git

• Delete unneeded plugins from /.../M2MBridge/plugins/xxx (optional)
• Install packages for m2mBridge core and plug-ins (https://docs.npmjs.com/cli/install:)
• Execute npm install --save at:
  • M2MBridge directory
  • Each plugin directory

  LLRPReader plugin depends on java module and you should use the following options in the the npm install call:

  GYP_DEFINES="armv7l=0 javalibdir=/usr/lib/jvm/java-7-oracle/jre/lib/arm/server/" CCFLAGS='-march=armv7' CXXFLAGS='-march=armv7' npm install

• If you get this error; var cwd = process.cwd(); Error: No such file or directory #200

M2MBridge execution

• Customize the bridge configuration bridgeConfig,json, defining the templateId with the bridge instance from DAP to clone Cloud Configuration
• Execute node m2mbridge.js (located in the M2MBridge directory)

Tools for configuration

• If you want to connect a device (like the LLRP Reader) to your PI by sharing you network you may want to run:

nm-connection-editor

Find there the connection that represents your ethernet card and configure in IPv4 Settings the method Shared to other computers

• If you want to guess the IP that is assigned through DHCP to a device connected by using the previously mentioned option, you can inspect the syslog with:

grep DHCPREQUEST /var/log/syslog

Remote debugging =

• Install VSCode in your machine https://code.visualstudio.com/
• If you need to modify the node code at the Raspberry Pi while debugging setup a share directory using samba
  • Install Samba
  • sudo apt-get install samba samba-common-bin -y
• At M2MBridge directory run node --debug-brk M2MBridge.js
• If you want to modify
