This document provides a YANG module description for managing a LoRa endpoints.
SemTech [LoRa] (c) is a low-rate, low-power, long-range radio technology. It could be used as a base radio technology for building Low-Rate Wide-Area Networks (LR-WAN), also known as LPWA (Low-Power Wide Area). SemTech [LoRa] (c) has the following characteristics:
The management of LoRa-based devices can be done through a standard approach, compatible with the best network-operator practices, namely NETCONF or RESTCONF. A formal definition of the parameters and the values to be managed is thus required, which can be done with the YANG module language. The following document presents a YANG module definition for managing a LoRa-based end-device.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
The data model has the following structure for Lora configuration:
+- RW lora
+- RW Lora Device
+- RW Mode
| +- RW Channel Bandwidth enumeration
| +- RW Coding Rate enumeration
| +- RW Spreading Factor int8
+- Physical Layer
| +- RW Preamblelength int32
| +- RW Channel Frequency Range enumeration
| +- RW Channel int8
| +- RW SymbolTimeout int32
+- MAC Layer
+- RW FrPayloadEncryption boolean
+- RW Delay int32
+- RW FixlengthPayloadOn boolean
The data model defines a state container Mode which includes the three principal characteristics of the LoRA interface which determine the parameters of the channel

This model imports typedefs from [RFC6991].
