End to end IoT Solution using Mongoose OS.
- 1. Developing a Complete Embedded IoT Solution Using Mangoose OS Mubeen Jukaku Syed Adil Emertxe, Bangalore
- 3. IoT - Definition Source: Gartner “The network of physical objects that contain embedded technology to communicate and interact with their internal states or the external environment.”
- 4. IoT – Reference Architecture
- 5. Use Case
- 6. Lockers ● Somethings to ponder on – Is my bank locker safe? – Is it possible that lockers are accessed without our knowledge? ● Is it possible so how we come to know about it?
- 12. Smart Lockers Device Access Point Node ` State : Open State : Open State : Open State : ON Bright ness: 80% Mode : Auto
- 13. Smart Lockers - Actors ● Customers :- – Every time the locker is opened the user gets an SMS / E-Mail ● Control Room :- – Based on the access time the control room gets the SOS to take appropriate access ● Insurance Providers :- – Upon subscribing to the required nodes the insurance providers get the intimation of theft or closure of the locker facility
- 14. IoT Hardware / Software Selection ● Security requirements ● Ease of development ● Data acquisition, processing and storage requirements ● Connectivity requirements ● Power requirements ● Physical device design ● Cost requirements
- 15. NodeMCU ESP32
- 16. NodeMCU ESP32 - Architecture GPIOs USB Interface LED SWITCH ESP32 ● Espressif Systems ● 32 Bit Core ● 520 Kbyte SRAM ● Ultra Low Pwr SOC BLE Wi-Fi

- 18. NodeMCU ESP32 – Development Support Arduino Espressif IoT Development Framework NodeMCU Lua Mongoose OS MicroPython, etc.,
- 19. Introduction to Mongoose OS
- 20. Introduction to Mongoose OS (MOS) ● An Open source OS for IoT ● Started as embedded web server. Expanded to an IoT OS ● Dual License, GPL or Commercial ● Development in C / C++ / JS ● Tool chain support on Windows, Linux, MacOS
- 21. MOS – Supported MCUs ● STMicro : STM32 F4, L4, F7 ● TI : CC3200, CC3220 ● Espressif : ESP32, ESP8266
- 22. MOS – IoT Cloud Integration ● Amazon AWS IoT ● Microsoft Azure IoT ● Google IoT Core ● IBM Watson IoT ● Private MQTT / Rest Backends
- 23. Device Logic (Application Code) Mongoose OS Core Timers, Events, etc., Mongoose OS Libraries Network, Cloud Support, Drivers, RPC, OTA, etc., Native SDK e.g, STM32 Cube, TI SDK, ESP-IDF, etc., STM32 L4, F4, F7 TI CC 3220, 3200 ESP32, ESP8266 Native OTA Support Remote Management TLS1.2, Mutual TLS HTTP, MQTT, Websoket, CoAP Wifi, Ethernet, BLE Firmware code can use Any functionality from The native SDK MOS – Architecture AWS / Azure / Google etc., (Cloud Backend)
- 24. MOS – Development Setup
- 25. MOS – Development Setup ● Download and Install MOS ● Understanding MOS User Interface ● Application (Blinky) ● mos.yml ● Building the firmware ● Flashing the firmware ● The output

- 36. MQTT Overview
- 37. MQTT – What? ● Machine-to-Machine(M2M) and IoT connectivity protocol ● Lightweight messaging protocol which works with a server-based publish subscribe mechanism ● Runs on the top of TCP/IP protocol suite ● Lighter than HTTP 1.1 and HTTP/2 protocols ● Popular among IoT, M2M, Embedded Projects
- 39. MQTT – Why? ● One-to-many distribution ● Ideal for constrained networks ● Supports QoS (3 Levels) ● For lower footprint and low power devices ● Simple implementation with set of commands to CONNECT, PUBLISH, SUBSCRIBE and DISCONNECT. ● Supports “Will” on abnormal disconnection
