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 (if LLRPReader is needed)

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer oracle-java8-set-default

Install nodejs

sudo apt-get install nodejs -y

sudo apt-get install npm

sudo npm install -g n

n 7.4.0

sudo apt-get remove nodejs -y

Install other requirement needed for building some libraries:

sudo apt-get install git autoconf libtool

Installs and configures Bluetooth core libraries (needed by bluetooth related plugins)

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

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

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

Allow non-privileged users (belonging to gpio group) to run GPIO commands (required by GPIO plugin):

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

cd quick2wire-gpio-admin

make

sudo make install

Add user that runs the bridge to communicate through serial ports (required by ArduinoSerial plugin):

adduser <username> dialout

Install dependencies for XBee radios

Install librxtx from ubuntu/debian repository as:

sudo apt-get install librxtx-java (check that the version is 2.2)

Create symbolic links in /usr/lib and run ldconfig to update library dependencies:

cd /usr/lib

sudo ln jni/librxtxSerial-2.2pre1.so librxtxSerial.so

Install snmp if you are planning to configure a SNMPDevice instance to monitor the Raspberry Pi

M2MBridge installation

Use your credentials to identify yourself in the UI at https://platform.amtech.mx
By using the menu go to Main menu > Sensors > M2MBridge application
Save M2MBridge.tar.gz to the directory of your choice
Untar the content:

tar xzvf M2MBridge.tar.gz

Delete unneeded plugins from M2MBridge/plugins/xxx (optional)
Install packages for m2mBridge core and plug-ins (https://docs.npmjs.com/cli/install)
Install a couple of requirements:
- sudo apt-get install libzmq3-dev libavahi-compat-libdnssd-dev libkrb5-dev
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-8-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

https://github.com/foreverjs/forever/issues/200

M2MBridge execution

Customize the bridge configuration bridgeConfig.json, defining the templateId with the bridge instance from DAP to clone Cloud Configuration
Set environment variable NOBLE_REPORT_ALL_HCI_EVENTS=1 (reporting all HCI events)
Execute M2MBridge.js startup script (located in the M2MBridge directory)

sudo NOBLE_REPORT_ALL_HCI_EVENTS=1 node M2MBridge.js


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:

<code>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

The ansible way

This guide assumes you already have ansible installed (detailed instructions in this guide)

In the directory of your choice, get a clone of the deployment project:
git clone https://github.com/AMTechMX/m2mbridge_deployment.git
Change directory to m2mbridge_deployment
Update your inventory by editing static_inventory file. Example:
```
 [rpis]
 10.0.0.10
 10.0.0.11
 10.0.0.12
```
Note: You need to configure private/public keys to access this hosts through SSH without password.
Configure common options in rpis/group_vars/all

Create a file for each host configured in rpi/host_vars whose name matches the IP address. For instance:

 plugins_enabled: [ SNMPDevice, LLRPReader ]
 bridge_description: Amtech M2M Bridge
 template_id: m2mCreator:m2mBridge
 bridge_id_prefix: tienda1
 location: {"wkt":"POINT(-99.17125583 19.40501031)","sContext":"geo"}
 address_country: usa
 address_city: Las Vegas
 address_road: Las Vegas Boulevard South
 address_number: 3960

cd into rpis directory
Run ansible playbook:
ansible-playbook -i static_inventory main.yml

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
- Configure share directory
  - http://www.htpcguides.com/create-samba-share-raspberry-pi/
At M2MBridge directory run
- node --debug-brk M2MBridge.js
At your laptop
- Open shared or local folder from vscode
- Configure launch.json https://code.visualstudio.com/Docs/editor/debugging
  - set "address": "raspberry-pi ip address" and "remoteRoot": "shared-directory name"
