Welcome back!

Connectivity is a defining attribute of the Internet of Things (IoT). A variety of technologies and techniques allow embedded devices to transmit and receive data. The intersection between connectivity requirements and physical and environmental constraints triggers the use of specific technologies. Low-power wide-area (LPWA) wireless communication technologies such as LoRa and LoRaWAN have shown practicality and ease of use in the field of Internet of Things. The LoRa modulation capability provides a longer communication range, making it an attractive choice in multiple IoT use cases. The energy efficiency and scalability aspects of the LoRaWAN protocol have sparked research curiosity around the challenges and opportunities of using the technology

For the LoRa part of our design, we choose the Adafruit RFM95W radio for both onboard gateway and end node (Bouy A or B)

Some of the high priority goals for implementing our LoRa

• Reduce SW development time in any way possible while maintaining quality.

• Allow for SW modularity and re-usability taking into account possible future developments (For example the possibility of a new HW revision with a change in

MCU or any of the sensors).

• Show the capabilities of the device by building sample applications that show the promise of using a LoRaWAN end device (long-range and low power).

• Adapt with Libraries for Bouy, and onboard gateway communication

• Make the LoRa stay connected for long with continuous ping from the onboard gateway to the bouy.
