The story of LoRa began in 2009 when Cycleo, a French company, invented LoRa. LoRa (Long Range) support for Zephyr OS goes back to December 2019. Since then, there has been a huge interest among the community to extend their support for it. More recently, LoRaWAN (low-power wide-area network) support was added to Zephyr OS. This will provide true networking support to Zephyr OS over LoRa. It operates in licensed free Sub Gigahertz frequencies (865 MHz-India, 868 MHz-Europe, etc…). It makes the perfect choice for low data rates and long-range applications. What is LoRaWAN? LoRaWAN is a MAC layer that sits on top of the LoRa. According to the OSI model, LoRaWAN is the MAC (media access control) layer while LoRa is the PHY (physical) layer. LoRa protocol is closed, meaning it is proprietary to Semtech, while LoRaWAN specifications are open to the public. The reference implementation is available at the GitHub repository. The end nodes transmit data to the [...]
