installed on '''bbb01'''

=== install node app + requirements ===
install node.js if required. Then:

sudo npm install express
sudo npm install morgan -S
sudo npm install body-parser -S
sudo npm install method-override -S
sudo npm install request -S
sudo npm install core-js -S
sudo npm install regenerator-runtime -S
sudo npm install exceljs -S

=== PM2 ===
pm2 is the app manager used for the node.js app. It starts automatically with the default user account (not root)
* logging
pm2 log --lines 600

* status
pm2 status

* initial start, or after removing app (don't do this if the app is already installed and running). In the app directory:
pm2 start server.js --watch --ignore-watch="node_modules"
pm2 save

* removing app from pm2
pm2 delete server

* reloading app
pm2 reload server

Thomas: /* Networking */

== Lam modified ==
* use 14400 as baud rate for FTDI; on Mac:
screen /dev/cu.usbserial-FTFO858O 115200
* default login is debian:
debian:temppwd
* '''P9 header is off by one, counting from 1.''' There is a extra GND row in position 3-4 ?

=== Time ===
* change time zone: '''sudo timedatectl set-timezone America/Los_Angeles'''
* install ntp: '''sudo apt-get install ntp'''

=== Networking ===
* the ethernet interfaces don't appear to work. Using Edimax wifi
* set manually
sudo ifconfig eth0 192.168.1.16 netmask 255.255.255.0
