Product Description

Overview
This document provides a user manual for the CHICKADEE Location Trackers developed by TEKTELIC Communications Inc. This document includes instructions regarding the HW capabilities. For the functional operation and SW behaviour, please refer to the TRM document.

The CHICKADEE is a low-power LoRaWAN IoT sensor powered by a Li-Po rechargeable battery and built into a compact IP67 polycarbonate casing. Its primary purpose is for location tracking both indoors and outdoors using a combination of location-tracking technologies:

GNSS: Outdoor tracking using satellite geolocation. There are two GNSS receivers built into Chickadee:
- Low-power GNSS (LPGNSS).
  Note: The acronym “LPGNSS” will refer to the LR1110 from this point on in this document.
- High precision GNSS using the ublox MAX-M10S receiver.
  Note: The acronym “GNSS” will refer to the MAX-M10S from this point on in this document.
Wi-Fi Sniffing: Outdoor and/or indoor tracking using Wi-Fi access point geolocation.

BLE Tracking: Indoor tracking using BLE beacon network localization.

The CHICKADEE is meant to be a component in an end-to-end location tracking solution as shown in Figure 1-1.1
LoRaWAN is the LoRa wireless communications standard protocol. This technology provides a low-bandwidth, low-power, and long-range2 means of transmitting small amounts of data. It has been developed with wireless sensing in mind, and to enable new means of gathering telemetry in numerous environments. The CHICKADEE supports LoRa and (G)FSK modulations according to the LoRaWAN L2 1.0.4 Specification [1]. The 150 MHz-960 MHz ISM bands are utilized to meet

NOTE: Only raw scan data is present in the LoRaWAN payloads, not sensor location information. In order to track and visualize a CHICKADEE’s location, an application server must be set up, integrated with the NS, and enabled to use the proper cloud location services. The information in this document is for the CHICKADEE sensor only; for information about setting up the rest of the end-to-end solution shown in Figure 1-1, refer to the TEKTELIC support portal Knowledge Base.

Up to 2 km NLoS and more than 22 km LoS. different application requirements from the standards and proprietary protocols of the given region.

The location information flows in this order:

CHICKADEE conducts LPGNSS, GNSS, Wi-Fi, and/or BLE scans to gather raw information from the available geolocation signal sources.
The raw scan results are conveyed via LoRa transmissions to 1 or more LoRaWAN GateWays (GWs).
The GWs forward the packets to the LoRaWAN Network Server (NS) either by ethernet or cellular backhaul.

The raw scan results are forwarded to the application layer via integration link.
The application determines which Cloud IoT Location Resolver Service(s) to use depending on what type of scan data is forwarded. TEKTELIC’s LOCUS application is designed to work natively with CHICKADEE, but any compatible 3rd-party application can be used.
The respective location resolver service processes the raw scan data to calculate a position fix.
- LPGNSS scan data messages are designed to be processed.
- BLE scan data messages are designed to be processed by TEKTELIC’s Geolocation Resolver Backend (GRB) and is supported by TEKTELIC’s LOCUS application.
- Wi-Fi scan data messages can be processed with 3rd party applications.

The resolved fixes are returned to the application where they can then be visualized on a virtual dashboard.

In addition to geolocation, CHICKADEE is a multipurpose device equipped with a variety of technology:

Core design: Based on the low-power, IoT-targeted STM32WB55CGU6 MCU, which runs the system SW and has a built-in BLE module. The MAX-M10S transceiver from u-blox handles the GNSS operations.

Accelerometer: Detects device motion state so geolocation updates can be sent more frequently while in motion. Motion alarms and the raw acceleration vector can also be reported if knowledge of sensor orientation is enabled.
BLE tracker mode: In this mode, the sensor is in BLE receive only to conduct geolocation tracking.
BLE beacon mode: In this mode, the sensor broadcasts BLE advertisements which make it discoverable by other nearby trackers or BLE-capable devices.

MCU temperature sensing: The temperature of the MCU can be reported, and additional reports can be sent if the conditions cross configurable thresholds.
Battery data: The remaining capacity and lifetime can be reported. The battery lifetime has been estimated to be 6 months with default configuration.

Summary of HW Information, Streams, and Default Behaviour
Table 1-1 presents the currently available sensor HW variants. The information streams supported by the SW are shown in Table 1-2 and the default configuration for reporting data has been shown in Table 1-3.

External Appearance and Interfacing
CHICKADEE enclosure is shown in Figure 1-2 and the locations of the external user interface hardware are identified. There are two buttons, the Function Button (FB) and the EMERGENCY button (EB). The Function button has three purposes and will act accordingly depending on how the button is pressed. These purposes are:

Activating the device: When shipped from the factory, a CHICKADEE unit is in DEEP SLEEP mode to conserve the battery capacity. To wake it up and have it join the network, press the Function Button once quickly, then press and hold the button for 3 s. After this button pattern the unit will turn on and try to join the network server.
Forcing an uplink3: Press the button and hold for 1 s to send an uplink which contains the battery status. The RED LED will flash indicating that the uplink was sent.

Resetting: Press the button once quickly, then press and hold the button for 3 s.

The EMERGENCY button is for placing the sensor in EMERGENCY mode from normal mode, and for cancelling EMERGENCY mode. More details are in Section 3.3.1.

Specifications and Sensing Functions
The CHICKADEE specifications are listed in Table 1-4. The main sensing functions are described in the following subsections.

Tracking with Geolocation
The primary purpose of the CHICKADEE is location tracking both indoors and outdoors using a combination of location-tracking technologies: GNSS, LPGNSS, Wi-Fi sniffing, and BLE scanning.
One or more geolocation scans are conducted during a geolocation cycle. A new geolocation cycle occurs at a regular period called the geolocation update period, as shown in Figure 1-3. By default, the geolocation update period is shorter when the sensor is in motion and longer when the sensor is still.

The satellite receiver can be configured to the user’s preference; either LPGNSS or GNSS. LPGNSS is chosen by default for NORMAL operation mode. Should LPGNSS fail to get a positioning fix, the user can set whether or not to use GNSS as a backup.
During a geolocation cycle, up to 3 scans can be defined and occur in sequence. After each scan concludes, if successful, the raw results are reported in a LoRaWAN UL before the next scan begins4.
The duration of each geolocation cycle may vary from 10’s of seconds to a few minutes, depending on several factors (e.g.: satellite signal strength, user configurable BLE scan duration, regional duty cycle limitations, etc.). It is important to configure the geolocation update period to be greater than the expected geolocation cycle duration, otherwise scans may not complete, and data may be lost. If LPGNSS scanning is enabled, it is not recommended to set the geolocation

If sending BLE scan results is paused due to regional duty cycle restrictions, the next scan (GNSS or Wi-Fi), if defined, will not begin until the duty cycle timeout expires and the BLE results are sent. update period to less than 3.5 min. If BLE scanning is enabled, it is not recommended to set the geolocation update to less than 20 s.
The supported scan type options and behaviours are summarized in Table 1-5.

Fail criterion: 0 BLE beacons detected.UL containing an empty list is sent.	Scan duration· Scan duty cycle· Up to 4 discovered BLE device filters

The scan order logic within the geolocation cycle is also configurable to allow the cycle to end upon a successful scan before the other defined scans occur. Doing so can save battery life in use-cases where the scan types can be prioritized by how likely they are to succeed, e.g.: if it is known that GNSS will be the available geolocation signal source 90% of the time. The supported scan order logic options are shown in Table 1-6.

Table 1-6: Scan Order Logic Options
5 The results of successful GNSS and Wi-Fi scan will fail to send if the sensor is restricted due to duty cycle at the time. Unlike other data reports, the scan results are dropped completely and not transmitted once the duty cycle timeout elapses. In these cases, if all other scans also fail, the geolocation cycle failed message will indicate this happened.

A:	1^st scan	→	2^nd scan if 1^st scan fails	→	3^rd scan if 2^nd scan fails
B:	1^st scan	→	2^nd scan	→	3^rd scan if 2^nd scan fails
C:	1^st scan	→	2^nd scan if 1^st scan fails	→	3^rd scan
D:	1^st scan	→	2^nd scan	→	3^rd scan

Geolocation Strategies
The ability to define up to 3 scan types and choose 1 of 4 scan order logic options results in 12 possible configurational combinations. This combination is called the geolocation strategy. Of the 12 geolocation strategies, only 7 result in unique device behaviour, as shown by the green shaded boxes in Table 1-7.

Table 1-7: Geolocation Strategies

Strategy Description	Scan Order Logic	Number of Defined Scans
Strategy Description	Scan Order Logic	3	2	1
FALLBACK 1st priority scan always done. Fallback to other scan(s) upon failure. End cycle upon successful scan.	A	#1	#2	#7
1 BACKUP 1st and 2nd priority scans always done. 3rd scan if both 1st and 2nd scans failed.	B	#3	#6	#7
2 BACKUPS 1st priority scan always done. 2nd and 3rd scans done if 1st scan failed.	C	#4	#2	#7
ALL SCANS All defined scans always done.	D	#5	#6	#7

The geolocation strategy used should be tailored to the use case of the CHICKADEE deployment. Some example use-cases and strategies are:

Outdoor remote worker: FALLBACK with (1) LPGNSS or GNSS (2) Wi-Fi, (3) BLE Likely to be outside for most of the time, so LPGNSS or GNSS is likely to succeed most of the time. Wi-Fi is next most likely, then BLE.

Indoor worker: 2 BACKUP with (1) BLE, (2) Wi-Fi, (3) LPGNSS or GNSS Likely to be in an indoor BLE Beacon network most of the time, so BLE is likely to succeed most of the time. If BLE fails, try both other methods to get a position estimate.

The default geolocation strategy is fallback (scan order logic A) with all 3 scans defined in priority order GNSS, Wi-Fi, BLE. The operational flow of this strategy is depicted in Figure 1-4. All other strategy flow depictions are shown in Appendix 1 – List of Geolocation Strategies.

With all geolocation strategies, if all scans fail, the geolocation cycle failed message is sent.

LPGNSS and Wi-Fi Operation
The LPGNSS and Wi-Fi scan results are formatted in such a way that the edge based to resolve the sensor’s position. Both UL and DL communications are exchanged between the CHICKADEE and server to transfer all the information needed for the positions to be resolvable.
For LPGNSS scan results to be valid and resolvable, the following are needed:

Valid clock synchronization: The internal time of the sensor must be synchronized periodically. T

Valid almanac: The almanac in the sensor must be kept up to date.
Assist coordinates: These help the resolver with an initial estimate of the sensor’s location. These can be configured specifically by the user if desired, but the SW will communicate to obtain assist coordinates upon startup if none are defined.

Wi-Fi scanning has no configurable options.

BLE Operation with LOCUS and the GRB
The BLE scan results are formatted in such a way that the TEKTELIC LOCUS application can resolve and display the sensor’s position. Indoor BLE beacon networks can be built virtually in LOCUS to match the physical setup. When LOCUS receives a sensor UL with raw BLE scan data, it forwards it to the Geolocation Resolver Backend (GRB) cloud service, which computes and returns the position estimate within the beacon network.
For information about setting up LOCUS, refer to the TEKTELIC support portal Knowledge Base. For a description of BLE scan behaviour, see the TRM.

MCU Temperature Sensing
CHICKADEE can send data for MCU temperature [°C], read from the MCU, in a LoRaWAN UL. Sampling cannot be disabled, but reporting can be disabled. By default, temperature is reported once every hour.
Threshold ranges can also be set such that moving in or out of range causes additional MCU temperature data reports.

Accelerometer Transducer
The CHICKADEE supports motion sensing through an integrated 3-axis accelerometer which can optionally be disabled. The main role of the accelerometer in the is to detect motion that can indicate a change of the sensor’s status from stillness to mobility, or vice versa.
The accelerometer generates an acceleration alarm when a motion event is detected that can be reported OTA. An acceleration event report is based on exceeding a defined acceleration alarm threshold count in a defined alarm threshold period. These thresholds can be customized such that there will not be multiple reports for a single event, depending on the definition of an event in a particular use case. An alarm event can only be registered after a configurable grace period elapses since the last registered alarm event. Carefully setting the grace period is important and prevents from repeatedly registering an accelerometer event.
In addition to alarms, detected motion can trigger the transitions between geolocation update periods. That is, when the Accelerometer Assist function is enabled:

When new motion is detected:
- A new geolocation cycle begins immediately.
- New geolocation cycles occur periodically according to the MOBILE geolocation update period.

When the motion has ended:
- A new geolocation cycle begins immediately.
- New geolocation cycles occur periodically according to the STILL geolocation update period.

The geolocation update periods are both configurable.
For location tracking, Accelerometer Assisted geolocation scans help to get location updates at appropriate rates: faster when moving and slower when still. Accelerometer Assist also helps to update the location at 2 critical times; when objects leave old locations and settle in new ones. Accelerometer Assist is enabled by default.
The accelerometer can also be polled periodically for its output acceleration vector for applications in which the sensor’s orientation is of interest.

BLE Beacon Mode
The CHICKADEE supports a beacon mode function as an alternative to geolocation tracker mode. The default mode of the sensor is tracker mode, so it must be switched into beacon mode.

When in beacon mode, no geolocation scans occur and the BLE operates in Tx only. It sends out periodic advertisements which are small packets of data. These packets are discoverable by other CHICKADEEs operating in tracker mode, as well as any other device capable of BLE scanning.
When in beacon mode, the sensor is still LoRaWAN-backhauled. That is, it can still send sensor data in LoRaWAN ULs and be reconfigured through LoRaWAN DLs. Furthermore, all other transducer functions are accessible in either beacon or tracker mode.
After a beacon joins the LoRaWAN network, it begins broadcasting BLE advertisements. This continues throughout normal operation as a background process.
The advertising interval is the time between the beginnings of consecutive advertisement transmissions as shown in Figure 1-5. It is user-configurable in units of [ms].

Figure 1-5 also shows that each single BLE advertisement comprises 3 individual packet transmissions, sent one after another on BLE channels 37, 38, and 396. This is to maximize the chances of a BLE device scanning on a single channel receiving 1 packet per advertising interval.
In addition to the advertising interval, the advertisement Tx power level is also a configurable operational parameter.
The BLE advertisement and LoRa radio transmission are mutually exclusive and never overlap. If any reporting becomes due, the BLE advertisements are paused while the LoRa activity is occurring.
The BLE advertising packet formatting supports 3 major BLE standards: iBeacon, Eddystone UID, and Eddystone TLM. By default, only iBeacon is enabled.

Setup of the Sensor

Included Product and Installation Material
The following items are shipped with each sensor:

1x sensor with 3.7 V Li-Ion battery installed. The battery is not replaceable by the user.
1x lanyard clip
1x Quick Start Guide

Unpacking and Inspection
The following should be considered during the unpacking of a new sensor. Inspect the shipping carton and report any significant damage to TEKTELIC. Unpacking should be conducted in a clean and dry location.

Do not discard the shipping box or inserts as they will be required if a unit is returned for repair or reprogramming.

Commissioning
Each sensor has a set of commissioning information that must be entered into the network server for the sensor to be able to join the network and begin normal operation once activated. For instructions on how to do this please refer to the Network Server Quick Start Guide (available online in the Knowledge Base). The commissioning info is included on the package labels.
You can find the commissioning keys inside the device box. If you don’t have the box, raise a ticket in our support portal and provide the T-Code, Revision and Serial Number on the label placed on the device.

Activation
The sensor is shipped in a secured enclosure with the battery preinstalled in a state of DEEP SLEEP. After unpackaging a CHICKADEE, the user must charge the battery when CHICKADEE is removed from the shipping box. This is done through the USB-C connector at the base of the unit by using a USB-C cable, or by the charge contacts, if so equipped (requires a custom adapter provided by TEKTELIC). The RED LED will be solid while the battery is charging and will turn to solid GREEN when charging is complete. Charging will take approximately 5 hours to complete.

Pressing the Function Button will activate CHICKADEE (see Section 1.3), and it will try to join the network server. When the CHICKADEE is activated, it will display an LED indication (described in §3.3) to show that it is beginning to join the network. It may take up to 10 seconds between the time of activation and the beginning of the LED join attempt pattern.

Once activated, the sensor will automatically begin the join process. CHICKADEE cannot be turned off by the user.

Battery Replacement
The battery is non-replaceable, return the unit to TEKTELIC for service.

Battery Charging

CAUTION: Do not attempt to open the sensor, there are no serviceable components.

CAUTION: Do not incinerate, disassemble, short terminals, or expose to high temperature –risk of fire or explosion or the leakage of flammable liquid or gas.
The CHICKADEE can be charged from a standard USB-C connector or through the external charging contacts on the bottom end of the module. Simultaneous application of power to both inputs in not allowed. Charging through the charging contacts requires the use of a custom charger cradle supplied by TEKTELIC.

Mounting
The CHICKADEE is primarily intended to be body worn using the provided lanyard clip.

The CHICKADEE may also be mounted to a material object using adhesive tape provided the module is mounted no more than 2 m above floor level.

Operation and Functions

Configuration
The CHICKADEE supports a full range of OTA configuration options. Specific technical details are available in the corresponding TRM documents. All configuration commands need to be sent OTA during the sensor’s DL Rx windows.

Default Configuration
Table 3-1 lists the default reporting behaviour of the CHICKADEE. Reporting behaviour can be changed from default through OTA DL commands.
Table 3-1: Default Reporting Periods

LED Behaviour
The LED behaviour is not user configurable.
The LEDs are normally off. Their blinking patterns reflect different actions and states of the sensor. At a high-level, the main patterns are summarized in Table 3-2. The detailed sequence and timings for each are described in the following subsections.

Table 3-2: Summary of LED Patterns

LED Pattern Meaning
GREEN blinking rapidly and a single RED flash every time a JOIN REQUEST is sent (~40 s)	JOIN mode; attempting to join the network
Single RED flash	UL sent
Single GREEN flash	DL received
Pattern for EMERGENCY	Entering and exiting EMERGENCY state, by pressing and holding the Emergency Button for 2 s
Solid RED⁷	Battery charging
Solid GREEN	Battery charging complete. GREEN LED will stay on until USB-C charging cable is disconnected.

EMERGENCY Mode
CHICKADEE is equipped with an Emergency Button (EB), which is used for the following purposes:

EB Active event: Pressing and holding the EB for at least 2 s sounds the buzzer8 with the emergency active buzz pattern, flashes the LEDs, sends location information, and makes a system state transition to the EMERGENCY state (if already not in that state). The buzzer will repeat the pattern every 10 s while in the EMERGENCY state.
EB Inactive event: Pressing and holding the EB for at least 2 s while in the EMERGENCY state turns the buzzer off, stops the periodic LED flashes, sends location information, and makes a system state transition to the NORMAL state.

Geolocation cycles and scan order logic, as explained in §1.4.1.1, are configurable while CHICKADEE is in EMERGENCY STATE.

7 While the battery is charging, the RED and GREEN LED activity for LoRa UL and DL are suspended.
8 The buzz pattern for entering and exiting EMERGENCY state is non-configurable.
