This article provides an in-depth look at MAC commands for LoRaWAN® network management. It is aimed at end-device software developers and team managers building devices using LoRa® that implement v1.0.4 of the LoRaWAN Link Layer Specification . This article helps you understand the different types of MAC commands, what each command does, and how to interpret them.
Already using software like LoRaMAC-Node™ to process MAC commands? This article gives you the background you need to understand how the software works, review the code, and be confident that your end device follows the standards and best practices defined in the LoRaWAN Link Layer Specification.
Send and receive MAC commands
MAC commands are sent from the web server to the end device in the downlink, or from the end device to the web server in the uplink.
There are two methods for sending MAC commands: either within the frame options ( FOpts ) field along with other data within the frame payload ( FRMPayload ), or as a separate packet using the entire frame payload.
