3.1 Introduction
This guide will help you get started with the devices and show you the various commands you may need to use
in demonstrating the functionality of the XT3630.
Each XT3630 is provided and labeled to show the product #, serial #, SIGFOX Identification 3 (SFID). For the
purposes of viewing the data on the SIGFOX portal, the SFID is the most important identifier for the end user.
The information pairing the devices with the SIGFOX ID is shown below:
The USB/Charging cable harness is shown below with the wire descriptions in the table to the right. The red
wire is the power input wire (8V-24V), the white wire “IN1” wakes the device with an 8-24V input, and the
black wire is ground.
3.2 Initial Configuration Example
The XT3630 needs to be can be configured to report based on a timer. The 9V wake cable will be the easiest
method to activate the devices. Simply attach a 9V battery to the connector cable and mate the 8-pin
connector with each XT3630 for 1-2 seconds to wake. When the device transmits, it will light up the orange LED
on the device which will confirm that the device is awake and operational. You can also check on which device
is awake by seeing if the unit reported in at the expected time. The device will send a ping to the server every
time upon wake.
The XT3630 Commands Description section will explain each of the commands and explain how to interface
with the device with the USB cable. Below is an example configuration:
+XT:4001,1,5,3
+XT:4002,1,50
+XT:4003,0,0,0,0,0
+XT:5401,8
+XT:3017,90,30,0,1
These configurations mean that the device will report the data packet per the established protocol to the
SIGFOX backend every 10 minutes. The GPS data is configured to be a minimum 50m accuracy to allow locking
at challenging locations. If the device is successfully awake. You will get data packets in the portal as shown
below:
The devices will begin to report once every 10 minutes.
3.3 USB Serial Cable Connection
To interface with the device for serial communication you must set up the RS-232 to USB adapter cable.
Connect USB cable from the cable harness to a PC. Install the drivers for the corresponding operating system on
the computer. The driver can be downloaded from the URL below:
 http://www.ftdichip.com/Drivers/VCP.htm
When the drivers are successfully installed, you should be able to see a USB COM port for the XT3630. Pick the
correct COM port for the XT3630 by looking for USB COM port under the ‘Ports’ section within Windows Device
Manager. Use the following terminal application settings:
1) Bits per second: 115200
2) Data bits: 8
3) Parity: None
4) Stop bits: 1

3.9 Example Device Behavior
This section describes XT3630 device behavior based on the following configurations:
+XT:4001,1,5,3
+XT:4002,1,50
+XT:4003,0,0,0,0,0
+XT:5401,8
+XT:3017,90,30,0,1
The sleep/wake configuration and the sleep timer are the most important commands to set correctly to set the
expected reporting behavior of the XT3630. The units have been configured with a sleep timer of 8 minutes.
This means that after the wait times defined in the 3017, the unit will enter low power mode for 8 minutes
until it wakes again to report per the 3017 configured timings. The flow chart below will show the expected
periodic behavior of this configured XT3630.
Sleep For 8
Minutes 
Wake and gather
sensor data for 90
seconds
(WT1)
30 second window
to Transmit to
basestation
(WT2)
The 4001, 4002, and 4003 command configure how the device will gather sensor data during the 90 Second
 period. Xirgo recommends using only the default WT1 and WT2 at this time. This can be further tuned if
necessary at a later time. The 4002 is set at a minimum of 50-meter accuracy, but that can be increased or
decreased as necessary.
Bluetooth is disabled by default, but can be tested if desired. The recommended test command for Bluetooth
advertising is:
+XT:4003,1,2,15,10,BLETEST
Any BLE scanning device should be able to detect the ‘BLETEST’ name and view the available advertising data
from the device.

E N C A P S U L A T E D
P A Y L O A D !
In order to transmit the data efficiently we need to create an encapsulation protocol which can support
message fragmentation.
To support this, we use a Group Index and a Message Index. Each Group contains some number of Messages.
Every Message indicates the Group, the Message Index and the total number of Messages in the Group. The
Message Index indicates ordering for payload concatenation.
The message above “THIS IS AN ENCAPSULATED PAYLOAD!” requires 4 SigFox messages to be transmitted
assuming 2 Bytes of framing information in the fragmentation protocol.
One Byte is reserved for the Group which is a logical 8-bit integer that will roll over at 256 (0-255). The second
Byte is reserved for the Message Index and the total Message Count. The Lower nibble of the 2nd Byte is the
Message Index within the Group and the upper nibble of the 2nd Byte indicates total number of messages in the
Group. ((Byte & 0x0f) + 1) == Message Index. (((Byte & 0xf0) >> 4) + 1) == Message Count. The (+1)
assumption being that there is at least one Message per Group allowing us a maximum of 16 messages per
Group and a maximum of 160 payload bytes per Group.

Highlighted fields are optional. When all of the Message Fragments are collected by the server and assembled
in order the server will have the total Message Size. 23 Bytes for no APs, 29 Bytes for 1 AP, 35 Bytes for 2 APs,
41 Bytes for 3 APs and 47 Bytes for 4 APs. Additional APs if required can be concatenated and determined
server-side based on ((Message Size – 23 Bytes) / 6 Bytes) == Number of APs at the end of the payload.
Any additional changes to the defined payload (Bytes 0 – 22) will cause an increment of the Payload Protocol
Version.

4.4 Xirgo Byte Packed Protocol (XBPP)
4.4.1 SIGFOX Payload Overview
In order to create a robust transport protocol, a standard header within the 12 Byte payload will include
information regarding the message which will provide the Alizent backend with information regarding each
message. This will allow the detection of a failed transmission if some SIGFOX message transmissions fail which
carry additional AP data. A standard message header including message type, version, index and count (total
number of messages), will be included in every message along with battery and AP information.
