Embedded Linux Conference

Bluetooth Mesh and Zephyr

Presenter:
Martin Woolley, Bluetooth SIG Developer Relations Manager – EMEA

Date and time:
28 October, 11:30am

Location: 
Forum 6

Description:
Bluetooth mesh was released in 2017 and allows secure networks of thousands of Bluetooth devices to be created. It uses Bluetooth Low Energy (LE) for radio communications and inherits its optimised, low power and other characteristics.

The Zephyr open source OS supports Bluetooth mesh on devices as affordable as the BBC micro:bit.

This session will explain the fundamental technical concepts of Bluetooth mesh, including models, messages, publish/subscribe, node composition and security keys and will explore what’s involved in implementing firmware that uses Bluetooth mesh on the Zephyr RTOS platform.

There will be code. There may even by live demos.

Location Services and Direction Finding with Bluetooth

Presenter:
Martin Woolley, Bluetooth SIG Developer Relations Manager – EMEA

Date and time:
28 October, 2:25pm

Location: 
Forum 3

Description:
Bluetooth acquired a new capability in 2019. It’s now possible with suitable hardware, to calculate the direction a Bluetooth signal is being transmitted from, using one of two methods known as Angle of Arrival (AoA) or Angle of Departure (AoD). From this, it’s possible to accurately determine the location of the receiving device to within a matter of centimetres rather than metres. Proximity applications like Point of Interest (PoI) information systems and the classic “key finder” are all set to get very accurate and much easier to use. Positioning systems such as Real Time Locating Systems (RTLS) and Way Finding will offer a level of precision, never before possible with Bluetooth.

Learn about this new Bluetooth feature and how it works under the hood, from the physics of radio waves upwards through the layers of the Bluetooth protocol stack.
