MySensors with NodeJS Controller and OTA bootloader on RPi

Hardware

Headless Raspberry Pi model B with wired Ethernet

I'm connecting a monitor only for first time boot to get the IP address and then connect via Putty/xRDP

Tutorials for this task are available on the internet (download, copy to SD)

(adjust to your needs - here: RPi-IP: 10.0.1.5 / Router-IP: 10.0.1.1 / password: test / timezone: Europe,Berlin / hostname: mysensors)

login as pi / test
sudo mkdir /opt/node
wget http://nodejs.org/dist/v0.10.28/node-v0.10.28-linux-arm-pi.tar.gz
tar xvzf node-v0.10.28-linux-arm-pi.tar.gz
rm node-v0.10.28-linux-arm-pi.tar.gz
sudo cp -r node-v0.10.28-linux-arm-pi/* /opt/node
rm -rf node-v0.10.28-linux-arm-pi/
sudo nano /etc/profile
NODE_JS_HOME="/opt/node"
PATH="$PATH:$NODE_JS_HOME/bin"
export PATH
sudo reboot
to confirm it's working as expected login as pi/test and run "node -v" which should return the installed node version (here: v0.10.28)

login as pi / test
sudo useradd -c mongodb -d /home/mongodb -m -U mongodb
sudo mkdir -p /opt/mongo/bin
sudo mkdir /var/lib/mongodb
sudo chown mongodb:nogroup /var/lib/mongodb
sudo mkdir /var/log/mongodb
sudo chown mongodb:nogroup /var/log/mongodb

sudo mv mongodb.conf /etc/mongodb.conf
sudo mv init.d /etc/init.d/mongodb
sudo chmod 755 /etc/init.d/mongodb
sudo update-rc.d mongodb defaults
sudo reboot
to confirm it's working as expected login as pi/test and run "/opt/mongo/bin/mongo" which should start the mongo shell (type "exit" to close the shell again)
if the RPi loses power without proper shutdown while mongod is running, you can't restart without manually removing the pid file first. To do so run “sudo rm /var/lib/mongodb/mongod.lock”

login as pi / test
git clone https://github.com/mysensors/Arduino.git
cd Arduino
git checkout development
cd NodeJsController
npm install
to confirm that the NodeJsController is working as expected and connects to the local mongo DB: "node NodeJsController.js" which should start the controller, connect to the database and run into an error connecting to the gateway. Stop node again via Ctrl-c

cd ~/Arduino/NodeJsController
chmod 755 *.sh
sudo cp MySensorsInitScript.sh /etc/init.d/mysensors
sudo mkdir -p /usr/local/var/run
sudo chmod -R 777 /usr/local/var/run
sudo update-rc.d mysensors defaults
sudo reboot
to confirm that NodeJsController is starting at boot, check the log file /home/pi/logs/NodeJsController.log

as described for the standard Serial Gateway - using the standard Serial Gateway sketch with DEBUG (in MyConfig.h) disabled
I'm using the version with inclusion mode button and LEDs based on no Arduino but a plain ATmega328p on a breadboard
Connect directly to the serial GPIO pins of the RPi:
Arduino GND <-> Raspberry Pi GND (pin 6)
Arduino RX <-> Raspberry Pi TX (pin 8)
Arduino TX <-> Raspberry Pi RX (pin 10)
Arduino RESET <-> Raspberry Pi GPIO22 (pin 15)
Right now I'm using a separate power supply for the serial gateway instead of the 3.3V or 5V pins of the RPi because I ran in some issues with power consumption during programming

sudo nano /etc/inittab
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
sudo nano /boot/cmdline.txt - remove part of the file:
~~console=ttyAMA0,115200~~
cd /dev
sudo ln -s ttyAMA0 ttyUSB9
sudo apt-get install minicom
sudo reboot

nano ~/Arduino/NodeJsController/NodeJsController.js
//const gwType = 'Ethernet';
//const gwAddress = '10.0.1.99';
//const gwPort = 9999;
//const gwType = 'Serial';
//const gwPort = '/dev/ttyAMA0';
//const gwBaud = 115200;
sudo service mysensors restart (at this point stop/restart doesn't work. use "sudo killall node" followed by "sudo service mysensors start" instead)

as described for the standard Ethernet Gateway - using the standard Ethernet Gateway sketch with DEBUG (in MyConfig.h) disabled
I'm using the version with inclusion mode button and LEDs based on no Arduino but a plain ATmega328p on a breadboard and the ENC28J60 Ethernet module
here: 10.0.1.99 / port: 9999

nano ~/Arduino/NodeJsController/NodeJsController.js
const gwAddress = '10.0.1.99';
sudo service mysensors restart (at this point stop/restart doesn't work. use "sudo killall node" followed by "sudo service mysensors start" instead)

cd ~/Arduino/Bootloader
make
this should compile the bootloader and produce three files in the same directory: MyOtaBootloader.o / MyOtaBootloader.elf / MyOtaBootloader.hex

cd ~/Arduino/Bootloader
nano Makefile
adjust avrdude settings to the available programmer. In my case (mySmartUSB MK3 programmer temporarily connected to RPi USB port):
ISP_PORT = /dev/ttyUSB0
ISP_SPEED = 115200
ISP_PROTOCOL = stk500v2
ISP_MCU = m328p
make load

nano ~/Arduino/NodeJsController/NodeJsController.js
const fwHexFiles = [ '../libraries/MySensors/examples/DallasTemperatureSensor/DallasTemperatureSensor.ino' ];
const fwDefaultType = 0;
sudo service mysensors restart (at this point stop/restart doesn't work. use "sudo killall node" followed by "sudo service mysensors start" instead)

in addition to watching the log file (tail command above) you can connect to the mongo db using a client (e.g. Robomongo) and check if new values are written to the database as a real end-to-end test once the bootloader finished uploading the firmware
