Smartico IS-LR Industrial Sensor LoRaWAN
**
Overview**
This document describes the hardware of the Smartico Industrial Sensor
LoRaWAN. The sensor has a wide range of peripherals that can be used by the
user in their own applications. The functionality of the device depends on the
application that is integrated and launched in the device. This document does
not describe the functionality of the device, but only contains a description
of the technical parameters and capabilities.
For the functional part, see the document “App Description” for the required
application.
The device can operate in the LoRaWAN 1.0.2 standard Class C or Class A.
Specifications
Hardware description
The device consists of two printed circuit boards located in one housing. The main board contains the LoRaWAN communication interface, the central processor (MCU) and the user interface. The second board is an extension board and contains a set of peripheral interfaces, a power supply and other elements. A detailed description of each board is described in the following sections.
Communication board
The sensor communication board is the main device and contains the microcontroller, wireless interface, and user interface. The main elements of the communication board are show in the Figure 1.

Table 2: Description of the Communication Board components
Extension board
The Extension Board contains a set of various I/O interfaces (digital inputs, analog inputs, serial interfaces). Also, this board can contain a power supply from an external source and a power manager. The power manager allows the device to automatically switch power to the internal battery when the external power is lost. The main elements of the communication board are shown in the Figure 2.

User Interface
Smartico Industrial Sensor LoRaWAN has several user interface components:
Internal Communication Interface
If there is no data cable supplied by the manufacturer, the customer can make
the cable himself. To communicate with the sensor, it is enough to use any
UART to USB converter and connect to three contacts (UART_RX, UART_TX and
GND). The pinout of the connector is shown in the Table 5.
4 Initial Setup
Device activation
- SERVICE: in this mode, various service operations can be performed with the device. Service operations are performed by the manufacturer and are not described in this document.
- ON READY: the device is in normal mode, but no activity is taking place in the radio air. In other words, the radio part is disabled in this mode. Sensor can be switched to this mode before long-term storage.
- ON AIR: normal operating mode of the device, in which data is transmitted via the LPWAN network. The SENSOR can be switched to this mode by command or by the influence of a magnetic field in the when it ON READY mode. Also, the
sensor is switched to this mode after 30 minutes of inactivity in the SERVICE mode
If the device has all the preset settings, then it can be put into operation
with a magnet, even without opening the housing. The place where you need to
bring the magnet is shown in the Figure 4.
Note: Hold the magnet for at least 40 seconds.
Data cable connection
To perform the initial settings of the device or to update the firmware, you
must connect the data cable to the
Communication Interface, as shown in the Figure 5. Make sure the marker on the
data cable is in the correct position.
After pressing the B1 button once, the sensor wakes up and is ready for via
the date cable. For a detailed description of
setting up the device, see the documents of AT Commands Description and App
Description.
The device supports secure firmware updates. The firmware file is loaded
encrypted and unpacked after being downloaded to the device. Only after
checking the integrity and authenticity of the firmware, the update process
begins.
When updating via data cable, the firmware file is transferred to the SENSOR
using the standard XMODEM file transfer protocol.
To complete the process of updating the firmware via the data cable, you must
perform the following sequence of actions:
-
Connect the data cable as described in the section 4.2
-
Using a terminal program (for example, Tera Term), should be opened the serial COM port with the following settings: 115200/8-N-1
-
To wake up the SENSOR you must press once button B1.
-
To synchronize the SENSOR interface, you must send the AT
command (where is a carriage return, code 0x0D). After one or more sent commands, the SENSOR should return an OK response -
Check the current firmware version by running the command:
AT+CGMR Possible answer: +CGMR: SW 1.13 HW 1.0
where SW X.XX – software version. In this case 1.13 -
It is necessary to enter the access code (8-digit number): Command:
AT+PIN=XXXXXXXX
Answer: OK -
Initiate the procedure for loading the firmware file into the SENSOR using the command:
AT+XMDM
Answer: +XMDM: OK
After executing the AT+XMDM command, the user has 30 seconds to start sending the firmware file via the XMODEM
protocol. This can be done using the terminal program Tera Term:
After selecting the file, file transfer procedure will start as shown in the figure:
After the successful transfer of the firmware file, the firmware update procedure will begin
After completing the firmware update procedure, you need to check the current version by running the command: AT+CGMR
