1. INTRODUCING THE DEVICE
1.1. Description
The Field Test Device (FTD) from adeunis® is a Class A 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 LoRaWAN Field Test Device from adeunis® is a ready-to-use device, which makes it possible to communicate with all network operators
using the LoRaWAN protocol. The system makes it possible to transmit and receive radio frames and to instantly view the results.
Equipped with a large LCD screen, you 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.
Thanks to its rechargeable battery, the FTD allows several hours of functioning and can be recharged using a standard mobile phone micro-usb.

4. DECODING THE PAYLOAD
The payload is divided into 2 frames to be compliant with regulation. The first byte (status byte) will enable you to identify the presence of
information contained in the payload.
These 2 frames are systematically transmitted in periodic mode or in event mode (button pressed or triggering of the accelerometer). Specifically,
during accelerometer triggering (following a vibration detected by the FTD), the MAC LinkCheckRequest command is issued and the LinkCheck-
Answer command is received back (symbolized by the ANS on the DL line of the display).
4.1. Frame 1 description
Information will always be shown in the order indicated in the following table.

This example will be used in order to explain how the payload is decoded.
if no GPS coordinate is available, only the Status byte (byte n°1) is sent.
if no GPS coordinate is available and transmission was generated from periodic transmission mode (no button pressed, no accelerometer), only
the first byte (status byte) is sent and its value will be 0x00.

5. DEVICE CONFIGURATION
The device can be configured using the USB connector. This connection allows you to communicate with the device via a virtual com port and
to transmit AT commands in order to modify the parameters of the device.
5.1. Connecting the device to a computer
Connect the Field Test Device (FTD) to the USB input of a computer. The FTD device has a Type B micro USB connector.
During connection, the device must be recognized by the computer as a Virtual Com Port (VCP) device.
Using Windows: Verification that the device has been recognized to be functioning properly can be obtained by consulting the device manager.
You should see the USB series device with a corresponding COM port number appear during connection.
If you are not able to see a device of this type, you must install the USB driver for this device, available to download from our website:

5.2. Command mode
Use a COM port terminal in order to communicate with the device. We use the HERCULES COM port soft terminal available to download for free
by clicking on the following link: http://www.hw-group.com/devices/hercules/index_en.html
• With Hercules, select the “Serial” tab, then configure the serial port with the following serial parameters:
Parameters Value
Rate 115 200 bps
Parity None
Data 8
Stop Bit 1
• Select the serial port on which the device has been created with Windows (Name).
• Click on the “Open” button to open the serial port.
PLEASE NOTE: If the com port has been opened correctly, Hercules will display the message “Serial COM3 port opened”.
Alternatively, “Serial port com opening error” will be displayed, meaning either that the com port is already open for another application, or it
does not exist.
• To supply power to the device, move the switch to the right.
Switch ON/OFF
Bottom view
You must send a specific frame in order to move the device to configuration mode.
Frame expressed in hexadecimals: 0xFF 0xFF 0xFF 0xFF 0xFF 0x2B 0x2B 0x2B
For Hercules, this frame must be entered in one of the 3 lines available at the bottom. The hexadecimal format must be expressed using a “$” in
this program, which gives us the following frame: $FF$FF$FF$FF$FF$2B$2B$2B
