The user must check the allowed bands, channels and transmission power, in order to respect the regulations in the operation country.
Libelium commercializes different items depending on the band the user wants to use. In the case of 868 and 433, the module is the same, but the antenna is different for each band. The module for EU (868) and 433 MHz includes 2 RP-SMA connectors for the antenna. One is for the 868 band and the other for the 433 band. A sticker on the bottom of the modules specifies clearly where to screw the antenna.
Any LoRaWAN module is provided with a special antenna (for 433 or for 868 or for 900 MHz), which enables maximum range.
Due to the propagation characteristics of the sub-GHz bands, the near field effect could make that 2 modules cannot communicate if they are placed very close (< 1 m). We suggest to keep a minimum distance of 3 or 4 meters between modules.

‌Time consumption

The elapsed periods defined in this chapter take into account the following steps depending on the case:
  • Join to a network and send unconfirmed data
  • Join to a network and send confirmed data
These periods of time depend on the data rate set which is defined by the spreading factor and signal bandwidth configured.
Transmit mode
Time elapsed (10-Byte packet)
Send unconfirmed at 5470 bps
~ 2.8 seconds
Send unconfirmed at 250 bps
~ 4.2 seconds
Send confirmed at 5470 bps
~ 1.7 seconds
Send confirmed at 250 bps
~ 4.2 seconds
Figure: Time consumption table
When transmitting in ISM frequency bands, the user must ensure that the communication is not exceeding the permitted time using the chosen frequency channel (for example, 1% of time). This depends on the local regulations (CE, FCC, etc). It is the responsibility of the user to know the allowed time of use in the occupied frequency band and respect it. Ignoring this, could lead to considerable penalties. Also, a LoRaWAN back-end operator could cut off the service or apply extra fees, it they detect that the user is exceeding the maximum number of frames or data in a period of time.

How to connect the module

This module can be connected to both SOCKET0 and SOCKET1 on the Waspmote board.
Figure: Module connected to Waspmote in SOCKET0
In order to connect the module to the SOCKET1, the user must use the Expansion Radio Board.

Expansion Radio Board

The Expansion Board allows to connect 2 communication modules at the same time in the Waspmote sensor platform. This means a lot of different combinations are possible using any of the wireless radios available for Waspmote: 802.15.4, ZigBee 3, DigiMesh, 868 MHz, 900 MHz, LoRa, WiFi, NB-IoT / Cat-M, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and RFID/NFC. Besides, the following Industrial Protocols modules are available: RS-485/Modbus and CAN Bus.
Some of the possible combinations are:
  • LoRaWAN - 4G
  • 802.15.4 - Sigfox
  • 868 MHz - RS-485
  • NB-IoT / Cat-M - WiFi
  • DigiMesh - 4G
  • NB-IoT / Cat-M - RFID/NFC
  • WiFi - 4G
  • CAN Bus - Bluetooth
  • etc
NB-IoT / Cat-M and 4G modules do not need the Expansion Board to be connected to Waspmote. They can be plugged directly in the socket1.
In the next photo you can see the sockets available along with the UART assigned. On one hand, SOCKET0allows to plug any kind of radio module through the UART0. On the other hand, SOCKET1 permits to connect a radio module through the UART1.
Figure: Use of the Expansion Board
The API provides a function called ON() in order to switch the module on. This function supports a parameter which permits to select the SOCKET. It is possible to choose between SOCKET0 and SOCKET1.
Selecting SOCKET0: LoRaWAN.ON(SOCKET0);
Selecting SOCKET1: LoRaWAN.ON(SOCKET1);
The rest of the functions are used the same way as they are used with older API versions. In order to understandthem, we recommend to read this guide.
Warnings:
  • Avoid to use DIGITAL7 pin when working with the Expansion Board. This pin is used for setting the XBee into sleep mode.
  • Avoid to use DIGITAL6 pin when working with the Expansion Board. This pin is used as power supply for the Expansion Board.
  • Incompatibility with Sensor Boards:
    • Agriculture PRO v30: Incompatible with Watermark and solar radiation sensors
    • Events v30: Incompatible with interruption shift register
    • Smart Water v30: DIGITAL7 incompatible with conductivity sensor
    • Smart Water Ions v30: Incompatible with ADC conversion (sensors cannot be read if the Expansion Board is in use)
    • Gases PRO v30: Incompatible with SOCKET_2 and SOCKET_3
    • Cities PRO v30: Incompatible with SOCKET_3. I2C bus can be used. No gas sensor can be used.
