LR1110 modem demo application

1. Description

The LR1110 modem demo application project contains several simple examples highlighting lr1110 modem features :

• Simple LoRaWAN Class A application 868/915 MHz:
  • The app joins automatically the LoRa Network server then sends uplinks periodically with the interval defined by APP_TX_DUTYCYCLE
• Simple GNSS example :
  • The unix date in ASCII is asked to the user through a terminal, once the date is received by the modem, it executes a GNSS scan periodically according to the gnss settings defined in the application
• Simple Wi-Fi example :
  • The modem executes a Wi-Fi scan periodically according to the Wi-Fi settings defined in the application
• Simple Tx continuous app :
  • The modem starts to send continuous wave
• Tracker example :
  • The app joins automatically the network then periodically :
    • Perform a Wi-Fi Scan
    • Perform a GNSS scan, the alcsync is needed
    • Stream the scan results

2. Usage
