	Micro-USB connector	The micro-USB connector allows you to charge the device.
	Charge indicator	The charge LED shows you the device’s charge status.

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).

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

Item	Icon	Description
GPS status	No icon	GPS has been deactivated
GPS status		GPS has not been synchronized

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.

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.

requency used for the request is shown after this information.

Item	Icon	Description
RF status	No icon	The JOIN phase is completed and the device is operational on the network
RF status		The device is in JOIN phase, and is trying to connect to the network

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.

Item	Icon	Description
Transmission Status	No icon	There is currently no radio transmission
Transmission Status		Manual transmission has been triggered (in progress)
Transmission Status		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.

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.

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).

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.
