Reading Blood Oxygen Saturation (SpO2) and Pulse through MySignals / Arduino

The MySignals HW BLE v2 – eHealth and Medical IoT Development Platform for Arduino contains sensors that measure more than 20 biometric parameters. One of the most interesting is the Bluetooth LE SpO2 sensor. How to get started reading live data and visualizing it on the TFT display of the board?

What is the MySignals HW Kit?

The MySignals HW kit contains a shield that requires an Arduino Uno as base. In contrast to the (more expensive) MySignals SW kit, the HW kit is rather basic. Powering it up results in a white screen, instead of a nice interface on the screen. The rest is up to the software developer. As the development is based on Arduino, you need the latest version of the Arduino IDE. Continue reading “Reading Blood Oxygen Saturation (SpO2) and Pulse through MySignals / Arduino”

Video: Everything You Need To Know About Bluetooth 5 & Beacons

Bluetooth Beacon Session by Andreas Jakl

With the first Bluetooth 5 devices just released (first and foremost the Samsung Galaxy S8), Bluetooth Beacons like Apple iBeacon and Eddystone by Google gain a lot of potential. Increased range means future beacons will cover a much larger area, without increased power consumption. With the payload increase of beacon advertisement frames from 31 bytes to 255 bytes, the amount of information transmitted by beacons can substantially increase.

In my session about Bluetooth Beacons at the Mobile Developer After-Work #14: Creating Immersive Environments, I provided a short update about the latest news. Unfortunately, recording of the live session at the event failed. Therefore, I’ve re-recorded it – you will miss the live experience, but I did have a little more time for more detailed explanations of some important facts, so it’s well worth watching again even if you have been at the #mdaw14 Event!

The 45 min recording is now available on YouTube.

How to Parse Bluetooth Beacons (iBeacon and Eddystone) with Arduino 101

Especially when working with Bluetooth Beacons like iBeacon or Eddystone, you will often want to use embedded hardware to create a low-cost, always running system. This short guide explains how to read Bluetooth Beacon messages using the Arduino 101 / Genuino 101 board.

The Arduino / Genuino 101 already includes a Bluetooth chipset and is based on the Intel Curie platform. You can use the same Arduino IDE as for all the other variants of the Arduino Board. Continue reading “How to Parse Bluetooth Beacons (iBeacon and Eddystone) with Arduino 101”
