Setting up Raspberry pi to act as MQTT Server/Broker (Raspberry Pi/Debian Equivalent)

Change hostname from raspberrypi to eazy exit using below command and then download required packages:
- ``` sudo raspi-config > Advanced Options > hostnames to eazyexit```
- ``` sudo apt-get update ```
- ``` sudo apt-get install mosquito mosquito-clients ```

• Mosquito broker will automatically start running on <your_pi_ip_address> port 1883

Setting up Development and Build system

• Hardware Supported (ESP8266 Nodemcu modules).

• Platform independent, only dependency is Python 2.7, pip installed.

• Make sure SiLabs CP21xx USB to Serial drivers are installed.

• Install and setup PlatformIO environment and command line tools

  • sudo pip install platformio

• Clone the repo into your local machine

  • git clone https://github.com/Team-SDIoT/EazyExit.git
  • cd EazyExit

• Fetch latest versions of submodules/dependent libraries using:

  • git submodule init
  • git submodule update

• In case above step doesn’t work clone libraries manually

  • cd EazyExit/EazyExit-Node/lib
  • git clone https://github.com/knolleary/pubsubclient.git PubSubClient
  • git clone https://github.com/ekstrand/ESP8266wifi
  • git clone https://github.com/tzapu/WiFiManager.git

• Edit "EazyExit/EazyExit-Node/lib/credentials/credentials.h" and add your WiFi SSID, WiFi password and IP address of server(Raspberry Pi) running MQTT broker

• Edit GPIO pin number EazyExit/EazyExit-Node/src/ESP8266.cpp if required default is pin D0 on which on-board LED is connected

• Build firmware using following command:

  • cd EazyExit-Node
  • pio run // Note: This will build and generate binaries for all supportive hardware
  • pio run -r nodemcu // Note: This will build and generate binary only for nodemcu hardware

• Build Server code using following command:

  • cd EazyExit/EazyExit-Server
  • change JAVA_HOME in setenv.sh
  • run build.sh as bash build.sh or make it executable to run as ./build.sh
  • run deploy.sh in the folder where Deployable.tar resides

• To manually flash the binary you will need to install esptool:

  • sudo pip install esptool

• Identify COMM port of board attached to your machine using Device Manager on windows and following command on Linux or MAC OSX

  • ls /dev/tty*, on mac and linux it is /dev/tty.SLAB_USBtoUART

• cd to directory holding binary:

  • EazyExit/.pioenvs/<Targer_Board> binary —> firmware.bin

• Flash using esp_tool:

  • esptool.py -p <COMM_PORT> —baud 460800 write_flash —flash_size detect 0 firmware.bin

TEST

• ESP node listens to MQTT messages<onn/off> on topic myHome
• On raspberry pi run mosquitto_pub -t myHome -m off LED should be off and mosquitto_pub -t myHome -m one LED should turn on.

Development Environment setup:

• Download PlatformIO official IDE "http://platformio.org/platformio-ide" or PlatformIO Plugin for ATOM IDE (http://www.atom.io)
