Installation

1. Install Arduino and following dependencies:

• https://github.com/arttupii/espNowFloodingMeshLibrary
• https://github.com/arttupii/ArduinoCommands
• https://github.com/arttupii/SimpleMqttLibrary
• https://github.com/kakopappa/arduino-esp8266-aes-lib (Only ESP2866)

2. Install esp8266 dev module. Use git version.

Instructions: https://github.com/esp8266/Arduino

3. Check Espressif FW version!!!. It should be nonos-sdk 2.2.1+100(testing). 

4. Add "https://dl.espressif.com/dl/package_esp32_dev_index.json" into the Additional Board Manager URLs field. 

5. Install esp32 dev module 1.0.3-rc1 from Arduino's Boards Manager. 

6. Flash Usb adapter software (EspNowUsb/EspNowUsb.ino) on esp32/esp2866 (esp32 is the best choice.). (You don't need to change any parameters)

• https://github.com/arttupii/EspNowFloodingMesh/tree/master/EspNowUsb

7. Install mqtt broker, nodejs and npm on RaspberryPi

      curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - 
      sudo apt-get install mosquitto nodejs npm

8. Get gateway and install npm modules

• https://github.com/arttupii/EspNowFloodingMesh/tree/master/gateway

      git clone git@github.com:arttupii/EspNowFloodingMesh.git
      cd EspNowFloodingMesh
      cd gateway
      npm install

9, Modify gateway/config.js file:

• set secredKey parameter (16 bytes)
• set initializationVector parameter (16 bytes).
• set bsid

10. Start gateway software on RaspberryPi. .

      a@labra:~/git/EspNowUsb/gateway/node index.js
      begin /dev/ttyUSB0 115200
      Subscribe topic device1/led/value from cache
      Subscribe topic device1/led/set from cache
      reboot
      Role MASTER, ttl=3
      MAC GET
      InitializationVector [178,75,242,247,122,197,236,12,94,31,77,193,174,70,94,117]
      key [0,17,34,51,68,85,102,119,136,153,170,187,204,221,238,255]
      Channel 1;
      Init
      RTC 1563876153

11. Open slave node code (arduinoSlaveNode/main/main.ino) and modify deviceName, secredKey, iv and ESP_NOW_CHANNEL paramaters.

• https://github.com/arttupii/EspNowFloodingMesh/tree/master/arduinoSlaveNode/main
• deviceName should be unique
• secredKey, iv, bsid and ESP_NOW_CHANNEL must be match to config.js file on raspberryPi. Otherwise mesh network won't work. --> Flash slave node
