Messages sent from an end device to a network server via one or more nearby gateways are referred to as uplinks.
In this book, you learn the rules and best practices to follow when sending uplinks from your end device using the LoRaWAN® 1.0.4 specification.
Sending MAC Commands
End Device Transmit Duty Cycle Answer (DutyCycleAns)
The end device sends the DutyCycleAns in response to the DutyCycleReq command. The DutyCycleReq command is sent by the network server to request a modification to the maximum aggregated transmit duty cycle of an end device which is lower than the regional limitation.
The DutyCycleAns is sent to confirm receipt of the request and does not contain any payload.
Learn more in Section 5.3, ‘End-Device Transmit Duty Cycle’ (page 32) of the LoRaWAN® Link Layer Specification v1.0.4.
