4 I. Introduction Sigfox Network Tester (SNT), is a Sigfox device provided exclusively for technology evaluation and network coverage reference measurements. Its primary functionality consists in periodic transmission of Sigfox radio messages meant for reception at any Sigfox Access Points. Each SNT has a unique network identity, printed on a sticker at the back and stored into its memory. With this ID, full retrieval of the device activity is possible through the OSS portal. SNT 1.1 is available in 4 versions to cover worldwide RF requirements: SNT1.1-1, SNT1.1-2, SNT1.1-3, SNT1.1-4 LED ON/OFF button Micro USB port Antenna
5 II. Requirements 1. Radio considerations SNT serves as reference device. It is equipped with a 1⁄2 wave antenna. For reference performance level, classical radio precautions have to be observed during operation: antenna vicinity has to be cleared of any metallic object, and antenna shall be kept in vertical position. Note that Sigfox Network optimal performance is obtained in stationary operation. 2. Cable connection SNT comes with a micro USB to USB cable. SNT is equipped with a rechargeable battery. When the device is connected to a USB charger or a USB socket of a computer, it will start to charge automatically (blue LED). The device can be used while charging. The battery takes about 3 hours to fully charge. SNT can be used and controlled by computer using the same USB cable. In this case, check the Software requirements (below). 3. Software requirements SNT is controlled by AT commands and works with Windows, Linux and Mac. Just make sure you to have: • FTDI drivers installed on your computer • Any soft to open serial port like Putty for Windows, Screen or Cutecom on Linux See SNT drivers installation guide for detailed information.
6 4. Registration in the Backend Each device needs to be registered in the OSS Portal (Backend interface). In Device type configuration, you can configure the display type. Depending on how you will use your SNT, you can configure it like this: • To have GPS location displayed in the Backend, select in Type: Geolocation and Default [Root] : • To get information about battery and frame counter, select Type : Custom and Custom configuration with : Vdd::uint:16 NA::uint:16 NA1::uint:16 NA2::uint:16 CounterDL::uint:16 CounterUL::uint:16 III. SNT operational modes SNT has two operational modes: standalone and serial communication. The device shall be used hand-held in upright position only. Alternatively the device may be used when put on the desk or an supporting structure. The device is not designed and must not be used nearby body like belt-worn, lanyard around the neck or put into pocket. 1. Standalone Pressing the button for a few seconds will activate the device. The LED lights blue as the device turns on. Then the device will execute the sequences described below. SNT has two main options: monodirectional (uplink only) and bidirectional sequences (uplink and downlink). By default, SNT is set to Uplink mode. These modes can be set by AT commands (see next chapter). These sequences are looped 10 times, then device shuts down automatically.
7 A. Uplink sequence Just after powering up, SNT sends a SIGFOX message every 10 minutes by default. This option can be set by AT commands. This message contains GPS information if available. When SNT is sending, green led is blinking. Between two messages, SNT led can be of one of these two colours: • Green if internal GPS is fixed • Orange if it is not the case B. Bidirectional sequence In this mode the device is sending and receiving frames. The LED colour is pink. The sequence is: 1. TX : device sending an uplink message. 2. IDLE: device in wait state (20 seconds) 3. RX: device in receive mode (timeout after 25 seconds) Depending on the reception result, there are two possible cases: > case 1: sequence completion by successful downlink frame reception 4. Led blinking in green, indicating successful message reception and send an OOB message 5. Link quality indication is displayed for 10sec (details below) Or > case 2: sequence completion timeout after 25 secs (NO frame received) 4. LEDs blinking in RED 3 times (~6seconds) Link quality indication: Providing the Backend direct callback is used and includes uplink RSSI, the link quality is flashed using a LED code: • LINK QUALITY = VERY GOOD → Blinks 3 times (WHITE) • LINK QUALITY = GOOD → Blinks 2 times (WHITE) • LINK QUALITY = AVERAGE → Blinks 1 time (WHITE) Note: The white LED may appear slightly pink.
8 C. Uplink frame format SIGFOX payload is composed of 12 bytes. The format of payload is available in the following table. Note: Vdd in mV 2. Serial AT commands operation AT commands can be sent to the device by connecting the USB cable to a computer and opening a serial interface. All the basics available commands are listed here: Commands Responses Descriptions and comments Default values AT OK Attention command. Just to be sure that all works fine! AT? <cmdlist> OK Requests summary of available AT commands AT&V <device info> Display device version information (SNT type, SW version, ID, PAC) AT$SF=<value>,<ack> OK Send a Sigfox Frame. Value must be in hex format by byte (ex : AABB74) AT$NC=<value> OK Change number cycle before shutdown. Value > 0. Or 0 for infinite 10 AT$NC? Current value 10 AT$BI=<value> OK Enable (1) or disable (0) bidirectional mode 0 AT$BI? Current value 0 AT$ID=<value> OK Change inter-message delay in seconds. 0 < Value < 65536 600 AT$ID? Current value 600 AT$GPS=<value> OK Enable (1) or disable (0) GPS. Value 0 improve SNT battery life 1 AT$GPS ? Current value 1 AT$FSD=<value> OK Set Delay before first message (in second) 0 < Value < 65536 2 AT$FSD ? Current value 2 AT$OT=<value> OK Enable (1) or disable (0) OneTouch mode (describe bellow) 0 AT$OT? Current value 0 AT$FP=<value> OK Enable (1) or disable (0) Factory reset. You need restart after with “ATR\r” command
9 AT$OT for OneTouch When this command is at 1, the SNT send only one Sigfox message instantly after having pushed the button. This frame is: “HELLO WORLD!” in ASCII. 3.
