Building IoT devices with ARM mbed - RISE Manchester
0 likes1,359 views
This document discusses building Internet of Things (IoT) devices using ARM mbed. It addresses three common problems in building smart devices: how to build them, how to connect them, and how to manage them. ARM mbed is presented as a solution to streamline development across multiple device platforms through its online IDE, code sharing capabilities, and libraries. Connectivity options for IoT like Bluetooth LE, WiFi, and cellular networks are reviewed. ARM's mbed Device Connector is demonstrated as a way to manage devices regardless of connection protocol through features like encryption and firmware updates. The presentation aims to help developers build their first connected device by walking through an example Bluetooth LE project.

- 1. Building IoT devices RISE Manchester 4 May 2016 with ARM mbed
- 3. Brought some help Jonny Austin Liyou Zhou
- 4. ARM Development Solutions Group:High Performance Ecosystem ARM Performance Libraries Open Source HPC Userspace Performance Tools Research Compilers Commercially- supported BLAS, LAPACK and FFT routines optimized for ARM-compatible microarchitectures. Identification of issues inARM builds of open-source packages and the upstreaming of fixes. New commercial tools to deliver actionable performance improvement advice to software developers. New compiler technology to support and evaluate next- generationARM Architecture. The mission: Enable the ARM Software Ecosystem for HPC and the Enterprise. 25 engineers in Manchester,UK (New location, founded July 2014).

- 6. Limited world view World is bigger than your pocket! Interact with the physical world
- 7. From the internet of humans to the internet of devices
- 13. Three problems How to build smart devices? How to connect these devices? How to manage these devices?
- 15. Unstreamlined Single-platform tools No code sharing Lack of libraries, documentation
- 17. Online IDE Code sharing Single way of building for all targets
- 18. 91 boards supported ~200 staff working on it 170,000+ developers
- 19. Open source embedded platform Operating system for microcontrollers Rock-solid HAL and libraries (e.g. Bluetooth)
- 20. Developing for mbed C / C++ (not as scary as it sounds) Large set of libraries Solid Bluetooth stack
- 21. Connectivity
- 22. Internet of Humans High bandwidth Low latency
- 23. Internet of Things Bandwidth seldom matters Latency might matter Range & Battery do matter
- 24. Cellular WiFi Zigbee Bluetooth Low Energy Thread / 6LoWPAN LoRa
- 25. unique position
- 27. Similar problems • Security? No green lock for IoT. • Manage devices over multiple protocols. • Firmware updates?
- 28. We have all the pieces • Security: mbed TLS and uVisor. • Protocols: set of vetted and field-tested libraries. • Updates? No one knows more about Cortex-M series than we.
- 30. mbed Device Connector • Single way of addressing devices, regardless of protocol • End to end encrypted with client side certs • Management functions
- 31. Available today • Free up to 100 connected devices. • http://connector.mbed.com
- 32. Connector demo's
- 33. Time to get hacking • Bluetooth Low Energy & WiFi • Developing devices • Plenty of prototype peripherals
- 34. Program • Let's build a connected device • BLE on the device, app on your phone • Toggle LEDs, keep track of buttons • After that: exercises or free hacking!
