OUR HISTORY WITH BLUETOOTH

www.henwaytech.com 4

We started in the early days of Bluetooth Classic (SPP and A2DP) Over 7 years experience with Bluetooth Low Energy (4.0, 4.2 and 5)

IN 2020

alone we’ve worked on over 12 unique Bluetooth projects. 3 more starting soon

5

⦿ Automotive rack tracking (Est. sales volume 300k Bluetooth radios per year) ⦿ LR Bluetooth radios powered by Hydrogen Fuel Cell technology for military use ⦿ Bluetooth apps for medical grade sanitation devices ⦿ Putting Bluetooth radios on K-9 units for next generation emergency response teams ⦿ and many more

BLUETOOTH DATA LOGGING

www.henwaytech.com 6

We can do anything involving reading from sensors, storing the data, and transmitting logged data via Bluetooth

Designed a battery powered device that resides near a motor shaft that counts the revolutions of the motor and its speed and sends this information over bluetooth

EXAMPLE

BLUETOOTH DATA LOGGING

www.henwaytech.com 7

Compact wearable Bluetooth designs in printed ink sensor application

Designed a battery powered device that auto-calibrates and auto-zeroes a conductive ink force sensor and sends this information over Bluetooth to a mobile app. The mobile app is able to keep connection with 2 devices simultaneously.

EXAMPLE

BLUETOOTH DATA LOGGING

Using Bluetooth to quantify machine performance and assist those responsible for preventative maintenance

A device that captures, analyzes in real-time, and buffers large amounts of data from a special motion sensor. Special algorithms are used to determine if motor vibrations are within tolerance. Operators can view this information on a mobile app in real time

• r download buffered data for in-depth analysis.

UP & COMING PROJECT

HIGH RELIABILITY

www.henwaytech.com 9

Transfer data safely without corruption

Designed battery powered device that took commands from a gateway and streamed accelerometer readings to the gateway via bluetooth. Imagine 6 devices and a hub that communicates with sensors one by one in a high vibration, harsh

• environment. Anything can happen

EXAMPLE

HIGH RELIABILITY

www.henwaytech.com 10 EXAMPLE

⦿ Made sure data was sent and received without corruption ⦿ Sensor values were stored until data was received ⦿ The system detected if the data was corrupted ⦿ Self recovery ⦿ Performed self-diagnostics ⦿ Sealed design non-user replaceable batteries

LONG BATTERY LIFE

www.henwaytech.com 11

We choose the best settings for the longest battery life. And we verify our results using SiLabs tools

EXAMPLE

Designed a sensor data-logging device where we needed to use advanced methods for optimizing the duration of data transfer and frequency.

HIGH SECURITY

www.henwaytech.com 13

We’ve implemented all three levels of Bluetooth built-in security and we’ve developed our own security and encryption

Designed a device that stores secret info that sends and receives sensitive information over Bluetooth to a mobile device or PC. We have also implemented our own security on top of the existing security

EXAMPLE

HIGH SECURITY

www.henwaytech.com 14 EXAMPLE

⦿ All the Bluetooth communication for this project, even the advertising data, was encrypted using AES-128 key ⦿ Implementation of a Diffie–Hellman 3072 bit key-exchange for pairing on an 8-bit device. ⦿ Secure OTA update (download encrypted firmware image, decrypt and update in real time)

BLUETOOTH AUDIO

www.henwaytech.com 15

We’ve used Bluetooth audio profiles for non-audio data transfer

Designed a battery powered medical device for contact-less heart rate monitoring

EXAMPLE

BLUETOOTH AUDIO

www.henwaytech.com 16 EXAMPLE

⦿ Analog circuitry captures the patient's heartbeats ⦿ Used a Bluetooth classic module running A2DP profile to send the heartbeat information encoded as audio signal to a mobile app ⦿ Mobile app records the information and shows it in real time ⦿ Low cost: there was no processor on the board,

• nly analog circuitry and Bluetooth classic

module.

APP-LESS WAY TO USE THE BLUETOOTH PROTOCOLS FOR IOS AND ANDROID

www.henwaytech.com 17 EXAMPLE

Designed a small, 3-Button device that fit on your finger for the adrenaline seeking selfie market

Control Android and iOS devices without installing any app

APP-LESS WAY TO USE THE BLUETOOTH PROTOCOLS FOR IOS AND ANDROID

www.henwaytech.com 18 EXAMPLE

Using 3 buttons and SIG standard profiles, the user can control their phone, in this way:

Play / Pause music. Play next / prev track Control phone volume Answer phone calls Switch apps Open camera app Take pictures / Capture video
