LoRaWAN-SX1272-Mbed-Shield¶

Overview¶

LoRaWAN-SX1272-Mbed-Shield application demo is a LoRaWAN Class-A device example project using LoRaWAN-lib and SX1272Lib libraries that send out sensors data.

Prerequisites¶

1. NUCLEO_L152RE board.
2. SX1272-mbed-shield board.
3. X-NUCLEO-IKS01A1.
4. Grove Red LED.
5. Grove Button.
6. Grove Rotary Angle Sensor.
7. mbed online compiler.
8. Tera Term.

Hardware Configuration¶

1. Connect SX1272-mbed-shield with NUCLEO_L152RE through Arduino connector.
2. Connect Grove Red LED with DIO_D6 port on SX1272-mbed-shield.
3. Connect Grove Button with DIO_D8 port on SX1272-mbed-shield.
4. Connect Grove Rotary Angle Sensor with ANA_A1 port SX1272-mbed-shield.

Software Configuration¶

The end-device must be configured with the following parameters:

• Commissioning.h
  • LORAWAN_DEVICE_EUI (8 Bytes) : Fist 3 Bytes is the Organizationally Unique Identifier (OUI) followed by 5 bytes of unique ID. If not defined by user, then the firmware automatically assigns one to the end-device.
    Ex:
    • #define IEEE_OUI 0x00, 0x00, 0x00
      
    • #define LORAWAN_DEVICE_EUI { IEEE_OUI, 0x00, 0x11, 0x22, 0x33, 0x45 }
  • LORAWAN_APPLICATION_EUI (8 Bytes)
    Ex:
    • #define LORAWAN_APPLICATION_EUI { 0x00, 0x00, 0x00, 0x00, 0x55, 0x66, 0x77, 0x88 }
  • LORAWAN_APPLICATION_KEY (16 Bytes)
    Ex:
    • #define LORAWAN_APPLICATION_KEY { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff }

Serial Terminal Display¶

• Use Tera Term to see the sending message:
  
  • button = 0 (if not press) button = 1 (if pressed)
    
  • rotary = 0 ~ 300
