3. Dual radio with the Expansion Board
Before starting to use a module, it needs to be initialized. During this process, configuration parameters are sent to the module.
USB and SD card are also initialized.
3.1. Expansion Radio Board
The Expansion Board allows to connect two 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,
DigiMesh, 868 MHz, 900 MHz, LoRa, WiFi, GPRS, GPRS+GPS, 3G, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and
RFID/NFC. Besides, the following Industrial Protocols modules are available: RS-485/Modbus, RS-232 Serial/Modbus and CAN
Bus.
Some of the possible combinations are:
•
LoRaWAN - GPRS
•
802.15.4 - Sigfox
•
868 MHz - RS-485
•
RS-232 - WiFi
•
DigiMesh - 4G
•
RS-232 - RFID/NFC
•
WiFi - 3G
•
CAN bus - Bluetooth
•
etc.
Remark:
GPRS, GPRS+GPS, 3G and 4G modules do not need the Expansion Board to be connected to Waspmote. They can be plugged
directly in the socket1.
Next image shows the sockets available along with the UART assigned. On one hand, SOCKET0 allows to plug any kind of radio
module through the UART0. On the other hand, SOCKET1 permits to connect a radio module through the UART1.
