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

Application 8, 9, 11
1. Connect NUCLEO_L152RE with X-NUCLEO-IKS01A1.
2. On top of X-NUCLEO-IKS01A1, connect SX1272-mbed-shield.
Application 13
1. Connect NUCLEO_L152RE with SX1272-mbed-shield.
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
    • Activation Type: OTA or ABP
      • OTA: #define OVER_THE_AIR_ACTIVATION 1
    • Network Type: Public or Private
      • Public: #define LORAWAN_PUBLIC_NETWORK true
    • 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. (For OTA)
      • #define IEEE_OUI 0x00, 0x00, 0x00
      • #define LORAWAN_DEVICE_EUI { IEEE_OUI, 0x00, 0x00, 0x00, 0x00, 0x00 }

      • #define LORAWAN_APPLICATION_KEY { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff }
    • LORAWAN_DEVICE_ADDRESS (For ABP)
      • #define LORAWAN_DEVICE_ADDRESS ( uint32_t )0x0
    • LORAWAN_NWKSKEY (For ABP)
      • #define LORAWAN_NWKSKEY { 0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3C }
    • LORAWAN_APPSKEY (For ABP)
      • #define LORAWAN_APPSKEY { 0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3C }
  • Configure.h
    • Communication Type: Hybrid or FHSS
      • Hybrid: #define USE_BAND_915_HYBRID
    • Join request Period:
      • 5 sec: #define OVER_THE_AIR_ACTIVATION_DUTYCYCLE 5000000 value in us
    • TX Period:
      • 5 sec: #define APP_TX_DUTYCYCLE 5000000 value in us
    • Uplink message: Confirmed or Unconfirmed
      • Confirmed: #define LORAWAN_CONFIRMED_MSG_ON 1
    • ADR(Adaptive Data Rate): ON or OFF
      • OFF: #define LORAWAN_ADR_ON 0
    • Default data rate: DR_0 or DR_1 or DR_2 or DR_3 or DR_4
      • DR_0: #define LORAWAN_DEFAULT_DATARATE DR_0
    • Application Type: 8 (IKS01A1) or 9 (IKS01A1+Cayenne) or 11 (Push Button) or 13 (rotary+Cayenne)
      • 9: #define LORAWAN_APP_PORT 9
    • Tx Power: 10 to 30
      • 20 dBm: #define LORAWAN_TX_POWER TX_POWER_20_DBM

Serial Terminal Display

  • Use Tera Term to see the sending message (baud rate: 115200):
    • button = 0 (if not press) button = 1 (if pressed)
    • rotary = 0 ~ 300
