Chapter 12. In the cloud, in the browser, and beyond
This chapter covers
- Using a cloud-based service (resin.io) to deploy and manage an application across a fleet of devices
- Bleeding-edge web platform technologies for interacting with hardware, including Web Bluetooth and the Generic Sensor API
- Building the Physical Web with the open Eddystone protocol and Bluetooth Low Energy (BLE) beacons
- Controlling hardware from a web page using Web Bluetooth and Puck.js
- Reading data from and writing commands to a BLE device
For this chapter, you’ll need the following:
- 1 BeagleBone Black and 5 V power supply
- 1 Espruino Puck.js
- 1 Adafruit BMP180 multisensor breakout board
- 1 half-size breadboard
- Jumper wires
This chapter opens up some grand vistas. Yet this grandness of scale bumps up against limited space. Topics merely touched upon here are entire specialties; there’s enough to learn about each to fill books, shelves, or even entire libraries: security; the web standards process; the intricacies of Bluetooth and Bluetooth LE (BLE) architecture; provisioning and managing fleets of IoT devices, at scale.
As such, this chapter doesn’t mark the end of a learning journey but is instead a springboard for subsequent adventures. Its first half pulls back the curtains on the world of cloud-based IoT service offerings. The second half wears a futurist’s hat, pushing at the edges of what we can do on the web and in a browser today, and at what might be coming tomorrow.
