General
This user guide relates to the economical AiRISTA Flow A1 small factor BLE only Tag.
Use Cases for the A1 Tag
The AiRISTA Flow A1 tag is a multipurpose BLE 4.2+ tag. The tag can be worn in a wristwatch
type format or on a key tag/ pendant or it can be attached to an asset that need to be
tracked. The tag has a single tactile push button on the center top of the tag. The tag has
optional Temperature and humidity sensors or a three axis Accelerometer.
The tag is over the air programmable and upgradable.
The AiRISTA Flow A1 tag uses the BLE network infrastructure to send data back to the
controlling server. In addition to beaconing the tag also scans for beacons so it could be
used in cases where people or assets can be associated to each other. Typical applications
for this are social distancing and asset monitoring so that assets/objects can stay within
parameters of each other. When no existing infrastructure is available AiRISTA Flow provides
low cost Wi-Fi/BLE gateways to transfer tag data to the controlling server.

Battery Replacement
The A1 tag can be opened by prying the front and back of the clam shell enclosure away
from each other. Do not insert any device in the square slot as that is where the sensitive
humidity sensor is located.
Once you have the 2 parts of the enclosure separated you will see the battery located in a
slide holder on the back of the PCB. Slide the battery (CR2032) out of the battery holder
and replace with a fresh battery in the same polarity as the one removed. (Negative side
towards the PCB.)

When placing the A1 Tag PCB back into the enclosure make sure you line up the 2
alignment pins inside the mold with the holes in the PCB.
After the battery was replaced close the A1 Tag by lining up the enclosure clips and then
pressing the 2 parts of the enclosure together.

A1 Tag Programming with nRF Connect
The tag should preferably be programmed by the controller server as it has over the air
capability (OTA).
The tag can also be re-configured from the standard default settings with the nRF Connect
application that can be run from any device that has Bluetooth technology and that has
the application to support it.
It is recommended that you contact your AiRISTA Flow representative for more information
on this process.
These are the default settings for the A1 tag:
RSSI Thresholdvalue in hex= 41 ui 8 - Contact distance
RSSI Threshold offset value in hex = 7 ui 8 -Warning distance = contact distance + warning
distance
prox out value in hex= 3c-00 sec ui 16= 60 sec ( 1 min)
prox in value in hex=84-03 sec ui 16= 900 sec (15 min)-contact duration
Values need to be converted to decimal when loading new values but they will be shown
in hexadecimal in the nRF Connect application.
Time keeping values are set in seconds.
