1. Basic information

Important: The Field Test Device (FTD) by Adeunis is a Class A & C LoRaWAN compatible device. This is not a point-to-point device and may not be used in this manner. This indicates that it must be used on a private or public operated network. The Field Test Device is a ready-to-use device, which makes it possible to communicate with all network operators using the LoRaWAN V1.0 protocol. The system makes it possible to transmit and receive radio frames and to instantly view the results. Equipped with a large LCD screen, the user can view various information relating to how the network being used is functioning (Uplink, Downlink, SF, PER, etc) in addition to information from sensors (GPS coordinates, temperature, battery level, etc). This device is specifically adapted for application validation, such as communicating sensors, tracking, smart building, metering, security and M2M. So the main purpose of the Field Test Device is to help the user to find good deployment sites for LoRaWAN end- nodes (or even base stations). The user will be able to make informed decisions: installing a node on a lamppost or the next one can mean a difference of many dBm, and thus, having or not a stable RF link. Thanks to its rechargeable battery, the FTD allows several hours of functioning and can be recharged using a standard mobile phone micro-USB.

The Adeunis Field Test Device also has 2 on-board sensors: a temperature sensor and an accelerometer. The accelerometer triggers a send a frame when a large vibration is detected (by shaking the device for example).

2.3. Screen description

The LCD screen of the product is split on few parts: •• The “Start” screen (it shows the firmware version) - Only on the powering up process •• The “Join” screen - Only on the powering up and after a command mode exit •• The “Uplink/downlink” screen (main screen) •• The “GPS” screen •• The “PER” screen (Packet Error Rate) •• The “Downlink frame” screen The following icons are present on each screen of the product: Item Icon Description GPS status No icon GPS has been deactivated GPS has not been synchronized GPS has been synchronized Temperature Temperature in °C Battery Battery level Product in charge 2.3.1. Start screen The device is switched on using the on/off switch located on the underside of the device. Once it has been switched on, the device’s LCD screen will light up and the start menu will be displayed. This screen shows the 2 firmware versions during few seconds. Figure: Start screen

2.3.2. Join screen

The device is configured to join the network using Over the Air Activation (OTAA). It starts a join request session (JRx) and shows the frequency, SF and power used during this session. When the product receives a Join Accept (JA) from the network, the information is displayed on the screen and the product switch to the main screen (uplink/ downlink). Figure: Join screen (join request and join accept) The requests are identified with “JR” followed with a number showing the number of requests done. The frequency used for the request is shown after this information. Item Icon Description RF status No icon The JOIN phase is completed and the dev ice is operational on the network The device is in JOIN phase, and is trying to connect to the network

2.3.3. Uplink/downlink screen

This screen is displayed when the device is connected to a network. Uplink and downlink transmission information will be displayed on the LCD screen. The 1st line shows the uplink information “ULx”, with x for the number and frequency of repetition. The 2nd line shows the Spreading Factor (SF) and the power used. The 3rd line shows the downlink information “DLx”, with x for the number and frequency of the reception window. The last line shows the SF, RSSI and SNR of the acknowledgement or frame received. Figure: Main screen Item Icon Description Transmission Status No icon There is currently no radio transmission Manual transmission has been triggered (in progress) Periodic transmission has been triggered (in progress) The downlink information displayed on the device relates to a downlink frame sent from a LoRaWAN network. If no information is found in this section, this does not indicate that the device is not working on the network but only that it has not received the acknowledgement from the network yet.

2.3.4. GPS screen

This screen can be accessed by briefly pressing the pushbutton 2 after the home screen. It allows to check the functioning information of the GPS module, as well as the device’s GPS positioning. Item Icon Description Number of satellites SAT xx Indicates the number of satellites received by the device GPS signal Indicator showing the quality of the GPS signal: •• 1 bar: weak reception •• 2 bars: average reception •• 3 bars: good reception Latitude Display showing latitude coordinates in degrees, minutes and seconds Longitude Display showing longitude coordinates in degrees, minutes and seconds When the GPS signal has not yet been “fixed”, no information on latitude or longitude will be displayed on the screen and the information icon will indicate that GPS has not been synchronized yet. 2.3.5. PER (Packet Error Rate) screen This menu can be accessed by briefly pressing the pushbutton 2 after the GPS menu. It allows to evaluate the quality of the radio connection between the device and the network. Figure: PER screen The screen will display: •• The number of frames sent (UL COUNT), including repetitions •• The number of frames received (DL COUNT) •• The Packet Error Rate (PER), as a percentage The PER measurement is calculated by comparing the number of frames transmitted to the number of frames received: PER (%) = 100 - (( DL_COUNT / UL_COUNT) * 100).

2.3.6. Downlink screen

This menu can be accessed by briefly pressing the pushbutton 2 after the PER menu. It allows to view a downlink frame sent by the network. This frame is displayed in ASCII characters. The non-printable characters are replaced by a point. Figure: Downlink screen

3. Working mode

The Libelium team has configured this device to be totally functional when the user receives the kit. In the case that the user needs to change any parameter or configuration in the Adeunis FTD, the user guide from Adeunis can be found on their website: https://www.adeunis.com/en/produit/ftd-868-915-2/. From Libelium we strongly recommend not to try to configure the device without deep knowledge on LoRaWAN networks. It is also recommended to get familiar to AT command if the user really wants to manipulate this product in advanced mode. 3.1. Enroll the device on the Loriot backend The Libelium team has already configured the module with all the required parameters to start working with the Loriot backend from the moment the device is turned on. The only configuration step left to the customer is the enrollment process of the device to the Loriot backend. In order to receive the packets on the customer Loriot account, the user must register the device in her Loriot customer account. The device comes with a document with LoRaWAN parameters. They must be used in the registration process in the “Adeunis Field Test Device Parameters” as follows: Figure: Adeunis FTD parameters document Customer must fill the form fields marked inside a red box with OTAA, the desired “title” and the previous parameters. Device Location parameters are optional. Figure: Enroll device

If the form has been filled properly, after clicking “Enroll”, there should be a new device among the other devices

registered in the Loriot application. Figure: New device Additionally, in the Loriot Application where the device has been defined, the “Gateway information” selection must be set to “Location data”. Figure: Loriot application menu

3.2. Testing the device

Once the device has been registered properly in Loriot, it can be turned on and start working. Refer to the “User interface” section to see how to power up the device and what to expect when the device is connected. To see the packets sent to the back-end from the device, Loriot has developed the “Adeunis GPS” websocket application. It parses the data and locates packets on a map. Figure: Websocket applications menu The application may take several minutes before showing packets and position. In order to show them, it is also necessary for the module to be sending packets with location. Before start sending packets, it is recommended to give a minute to the device so it gets GPS coverage. Once the device shows its position, pockets should start being shown in the application. Remember to select the Adeunis FTD registered unit in the application within the Adeunis GPS app. Figure: Selected device menu

On the left side of the map, there is a box that shows the information of the last packet received. On the right

side, there is another box that shows a list with some information of the packets stored in the database. Dots are displayed in the map indicating the place where the packets were sent from. Figure: Adeunis GPS application

3.3. Universal Ranger application

Besides the Adeunis GPS application, Loriot provides a Universal Ranger that also shows the strength of the signal and location of packets in a map in a very similar way to the Adeunis GPS application. It is also fully compatible with the Adeunis FTD. Please check the Network Ranger Application Guide if you are interested. Figure: Universal Ranger application

3.4. General recommendations

Before starting the test, we advise to power up the device close to the base station, and having a computer with access to the Loriot back end, in case there is some configuration that hasn’t been done yet. Once the device shows data in the application, the test shall begin correctly. The device is prepared to work using th ADR (Adaptive Data Rate), so Libelium has configured it to start working with SF7 (spreading factor 7). This is the fastest wireless transmission mode, but bear in mind that it is the worst mode for getting long distances. If the packets do not reach the gateway during the test, the device will automatically change SF from SF7 to SF12. The higher is the spreading factor, the longer is the range. If the packets do no reach the gateway, the user will see that the device does not receive ACK frames. This will mean that the user has exceeded the limit of the coverage area. If the customer is interested in sending a high number of packets per day, attending always to the country regulations, it is recommended to find places where the device can send with lower spreading factors. The lower the spreading factor is, the faster the transmission of the packet is (as packets take less time on air, more packets can be send). It is also recommended to restart the Adeunis FTD at every location in order to check that the device joins properly to the network.
