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 [1].
Figure 1-1: CHICKADEE Location Tracking End-to-End Architecture The location information flows in this order: 1. CHICKADEE conducts LPGNSS, GNSS, Wi-Fi, and/or BLE scans to gather raw information from the available geolocation signal sources. 2. The raw scan results are conveyed via LoRa transmissions to 1 or more LoRaWAN GateWays (GWs).
§1 Product Description CHICKADEE UG 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 LR1110 transceiver from Semtech handles the LoRa, LPGNSS, and Wi-Fi operations.
Disabled 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.
§1 Product Description CHICKADEE UG a. 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.

CHICKADEE UG 1.4.1 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.
§1 Product Description CHICKADEE UG 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.
§1 Product Description CHICKADEE UG 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.

§1 Product Description CHICKADEE UG 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.
The GNSS and Wi-Fi scan results are formatted in such a way that the edge based LoRa Cloud service can resolve the sensor’s position. Both UL and DL communications are exchanged between the CHICKADEE and LoRa Cloud server to transfer all the information needed for the positions to be resolvable.
[2]. For a description of BLE scan behaviour, see the TRM. 1.4.2 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.
1.4.4 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.
§1 Product Description CHICKADEE UG 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.
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.
The battery is non-replaceable, return the unit to TEKTELIC for service. 2.5 Charging 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.
§2 Setup of the Sensor CHICKADEE UG 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. Figure 2-3: Adhesive Tape Mounting Area T0008814_UG_v1.4 TEKTELIC Communications Inc.
3 Operation, Alarms, and Management 3.1 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.
§3 Operation, Alarms, and Management CHICKADEE UG 3.3.1 Power-On and Network Join Patterns When the sensor is activated or reset: 1. Both GREEN are OFF for approximately 0.5 s after any reset occurs. 2. Upon startup, the SW conducts its POST. Both...
