1. Overview
The Revolar Instinct product is a personal safety device (PSD). The product is a personal
safety alert button that will predominantly be used by those working in the new and growing
“sharing economy” and by young women. The sharing economy includes fields like Lyft & Uber
drivers, Real Estate Agents, and others who constantly work with unknown individuals, in strange
locations and in largely unregulated industries. The purpose of the PSD is to enable the user to
discretely, and rapidly notify their support network that they may be in danger, and where they are
located.
Other markets include young children, the elderly, and those who suffer from medical conditions
that may need urgent help without the ability to use a smartphone in the event of the emergency.
This document serves as a Source information for schematic capture, layout and DVT process.

The Revolar Instinct personal alert button uses Bluetooth Low Energy to communicate an
emergency alert to the user’s cell phone where a Revolar Instinct App relays the alert to the Revolar
Instinct Cloud Services.
The button hardware design is built around the Silicon Labs EFR32 Bluetooth Low Energy
SOC. The embedded ARM Cortex-M microcontroller runs both the Silabs BLE software stack and
the Revolar Instinct button firmware. Peripheral devices include a single SPST push-button to
initiate an alert and a haptic and beeper for indication of button status.
The button implements a single, proprietary Bluetooth LE service that in turn implements
three characteristics or attributes.




Revolar Instinct Status – a read/notify characteristic that reports the button’s alert
status
Revolar Instinct Control – a write only attribute used to acknowledge receipt of
alerts and control the button’s internal state
Revolar Instinct Query/Response – a read/notify/write attribute that is used to query
and/or set various values within the button. Among other things, this attribute
supports reading the Manufacturer Name string, the button Model string, the
firmware version and the firmware date. It is also used to read and write a
customized name for the button (ex. “Jane’s button”). Other functions include Overthe-Air Download of firmware updates, initiating radio test modes for FCC
qualification testing, and debug functions.
Revolar Instinct Checkin – a read/notify/write attribute that reports and manages
requests from the button for an end-to-end systems check-in and find my Revolar
Instinct
2. Features:
 Delivers emergency alert messages to friends, loved-ones or a 24/7 call monitoring service
 Communicates to the Revolar Instinct cloud services using the smartphone (iOS or Android)
as the user interface device and as the communications transport

4. Operation Details – push button functions and haptic beeper
indications
The Revolar Instinct haptic operation consists of one basic mode. Short vibration is vibrating for
250 mS. Then, stop vibrate. And the Revolar Instinct beeper operation consists of three basic modes.
One chirp sound is on for 50 mS, two chirp sound is on for 50 mS then stop for 50 mS and chirp
sound again for 50 mS, three chirp sound is chirp 3 times toggle between chirp and stop with 50 mS
interval.
Desired Action
How to Initiate
Trigger Yellow Alert
Vibrate 250ms
Single press & release with a press duration < 4

Double press & release with a total duration
from start of first press to release of second press
< 1sec
Trigger Safe Check-In
Checking on application
Press and hold for 1 seconds (and less than 6
seconds) until a single chirp sound occurs, then
release.
Watch for response sequence…
Trigger Pairing
Press and hold for 6 seconds (and less than 20
seconds) until a 2-chirp sound occurs, then
release.
Response…
A sequence consisting of 2 chirp sound indicates that
the 6 second hold period has been reached.
It perform pairing mode for duration of 30 seconds.
Upon successful pairing, application will show
success pairing.
If the 30 second pairing window expires without
successful pairing, device will return to sleep mode.
Trigger Button Reset
Press and hold for 20 seconds until 3 chirp sound
occurs, then release.
A sequence consisting of 3 chirp sound that the 20
second holds period has been reached. A reset will
occur.
Responses sequences are button perform reset and
power on self-test.
** After detection of a fatal error, the button firmware will wait for a push-button interrupt.
Pressing and releasing the push-button will result in a firmware initiated reboot.
The Silicon Labs EFR32 Bluetooth SOC chip provides all of the processing power of the
Revolar Instinct button. It executes both the Silabs Bluetooth software stack and the Revolar
Instinct firmware. The integrated single-image firmware is programmed into the EFR32 during
manufacturing via bed-of-nails test points on the bottom of the PC board using SWD protocol.
Revolar Instinct shall provide Celestica manufacturing with the firmware in an industry
standard .HEX file format as produced by the Simplicity Studio development system.
The Segger J-Link attaches to a computer system via USB and can be used with the J-Link
Programmer application to program the EFR32. It is possible to program all button instances within
a PCB panel simultaneously. Programming details and tools are found via the URLs below.

6. Environmental Requirements
The Revolar Instinct button shall meet the following environmental requirements
 IP68 water resistance
7. EMC Requirements
The Revolar Instinct button shall meet all EMC requirements necessary to pass FCC
specifications for EMC emissions – intentional. The Revolar Instinct firmware provides a
mechanism to initiate four special radio-testing modes used to perform the necessary EMC testing.
The initiation of these radio-testing modes is documented in a separate file “Button RF Testing
Modes”.
