LoRa Peer-to-peer (P2P) Demo with REYAX RYLR998

LoRa Peer-to-peer (P2P) allow direct communication between LoRa end nodes without LoRaWAN gateway. This video explains how to use LoRa P2P with REYAX Technology RYLR998 module with Semtech engine and NUVOTON MCU. This LoRa model is controlled through USB to UART converter and AT commands. REYAX RYLR998: https://reyax.com/products/rylr998/ LoRa is a wireless modulation technique derived from Chirp Spread Spectrum (CSS) technology. It transmit small chunks of data with low bit rates over long range. LoRa operates on the license free sub-gigahertz bands and requires low power. LoRa was developed by Semtech. LoRa Radio Frequencies: Europe EU868 (863–870/873MHz) North America US915 (902–928MHz) South America AU915/AS923-1 (915–928MHz) India IN865 (865–867MHz) Asia AS923 (915–928MHz) LoRaWAN is a Media Access Control (MAC) layer protocol on top of LoRa for managing network communication between end nodes and gateways, developed and maintained by the LoRa Alliance. LoRa Peer-to-peer (P2P) allows direct LoRa communication between end node devices (peer-to-peer). The benefit is the low cost of the infrastructure because LoRaWAN gateways are not needed.
