I. Introduction
SNT, for Sigfox Network Tester, is an SIGFOX demonstration transceivers provided
exclusively for technology evaluation and network coverage reference measurements.
Their primary functionality consists in periodic emission of SIGFOX radio messages meant
for reception at any SIGFOX Access Points. Each SNT bears a unique network identity,
printed on a package sticker and stored into its memory. With this ID, full retrieval of the
device activity is possible through the Backend interface.
II. Requirements
1. Radio considerations
SNT serve as reference device. It is equipped with a 12 wave antenna. For reference
performance level, classical radio precautions are to be observed during operation: antenna vicinity
(3λ=1m @ 1GHz) has to be clear of any metallic object, and antenna shall be kept in vertical position.
Note that SIGFOX Network optimal performance is obtained in stationary operation.
2. Hardware requirements
SNT can also be used controlled by computer. In this case, you need :
Micro USB cable
Software requirements (bellow)
3. Software requirements
SNT is controlled by AT commands (describe bellow) and works with Windows, Linux and Mac.
Just assure you to have :
FTDI drivers installed on your computer
Any soft to open serial port like Putty for windows, Screen or Cutecom on Linux

III. SNT manual operation
SNT have two operation mode : standalone mode and serial communication.
1. Standalone mode
Pressing the button for a few seconds will activate the device. Then the device will execute the
sequence described below. SNT have two mains option : uplink only and bidirectional sequences.
These mode can be set by AT commands (see after)
By default, this sequence is looped 10 times, and device shuts down automatically.
Uplink sequence
Just after power up, SNT send a SIGFOX frame every 10 minutes by default. This option can be
set by AT commands. This frame contains GPS informations if available.
When SNT is sending, green led blinding.
Between two sent, SNT led can be of one of these two colours :
Green if internal GPS is fixed
Orange in other case
Bidirectional sequence
This sequence is :
1. TX : device sending an uplink message.
2. IDLE : device in waitstate (20 seconds)
3. RX : device in receive mode (timeout after 25 seconds)
Depending on the reception result, there are two possible branches :
> branch 1: sequence completion by successful downlink frame reception
4. Led blinding in green ,indicating successful message reception and send an OOB message
5. Link quality indication is displayed for 10sec (details below)
or
> branch 2: sequence completion by 25 sec timeout (NO frame received)
4. LED blinking in red at the same time 3 times (~6seconds)
Link quality indication :
Provided the Backend direct callback is used and includes uplink RSSI (*), the link quality is flashed
using a LED code (sequence step 4)
LINK QUALITY = VERY GOOD → Blinks 3 times (WHITE)
LINK QUALITY = GOOD → Blinks 2 times (WHITE)
LINK QUALITY = AVERAGE → Blinks 1 times (WHITE)
LINK QUALITY = LIMIT → Blinks 3 times (RED)
