Can two RN2483 (or RN2903) modules communicate point-to-point (P2P) without a gateway?
The RN2xx3 family of products is designed to support the LoRaWAN™ open standard as published by the LoRa Alliance™. The LoRaWAN architecture dictates a hierarchical structure of gateways and network/application servers and has no concept of point-to-point (P2P) communication.
Microchip is a founding member of the LoRa Alliance and the LoRa product line is fundamentally aligned with LoRaWAN protocol. Although the underlying modem hardware would be capable of P2P links using LoRa modulation, we do not promote or support P2P.
