A1Tag Personnel Asset Temperature Multi Tag
User Guide
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 upgradeable.
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 with 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.

A1 Tag Activation and De-Activation
Press the button on the tag and the tag will activate.
The tag will automatically de-activate after 15 minutes if it is not in
motion. (Not moved)
Press and hold the button for 5 seconds to force the tag to reset. This action
will stop the tagging process and the button needs to be pushed again to
activate the tag.
Battery Replacement
The A1 tag can be opened by prying the front and back of the clamshell
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 it 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.
FCC Statement
This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
