LoRaWAN ® Certification Protocol Specification TS009-1.2.1 ©2024 LoRa Alliance ® Page 6 of 27 The authors reserve the right to change specifications without notice. 2 Introduction 163 All messages described in this document are transported as application layer messages on a 164 dedicated port. As such, all unicast messages (uplink or downlink) are encrypted by the 165 LoRaWAN Media Access Control (MAC) layer using the end-device's AppSKey. 166 167 This protocol specification allows the LoRaWAN Certification Test Tool (LCTT) to fully validate 168 compliance of an end-device to the LoRaWAN L2 Specification [TS001] and the LoRaWAN 169 Regional Parameters Specification [RP002] for Class A, B, and C end-devices and end- 170 devices that support the Static Context Header Compression (SCHC) protocol. 171 172 In order for an end-device to be designated "LoRaWAN Certified CM " it SHALL implement this 173 application layer specification and have Port Field (FPort) 224 enabled for the duration of 174 the certification tests. This FPort SHALL be disabled on any device in production. Otherwise, 175 it may intentionally or accidentally be activated to harm the device itself or the networks in its 176 radio coverage. 177 178 The end-device to be certified SHALL be sent to an Authorized Test House (ATH) with FPort 179 enabled for the certification test and will then be returned to the end-device manufacturer for 180 FPort to be disabled. 181 182 The following flow chart describes the process: 183 184 185 Figure 1: Certification process flow chart 186 187 When an Over-the-Air Activation (OTAA) device has connected to the Test Control Layer 188 (TCL, refer to Chapter 3, "Functional Test Description for LoRaWAN Certification") after the 189 Join-Request and Join-Accept frame exchange, the device SHOULD send an uplink message 190 as soon as possible. 191
