	  Enables handling of SMP commands received over LoRaWAN.

	int "LoRaWAN SMP frame port"
	range 1 223
	default 2
	help
	  LoRaWAN download and uplink frame port used for communication. All messages received on
	  this port will be treated as SMP packets.

config MCUMGR_TRANSPORT_LORAWAN_CONFIRMED_UPLINKS
	bool "Use confirmed packets for uplinks"
	default y
	help
	  Will use confirmed uplink packets for responses if enabled, otherwise will use
	  unconfirmed packets.

config MCUMGR_TRANSPORT_LORAWAN_REASSEMBLY
	bool "Reassemble LoRaWAN SMP messages"
	select MCUMGR_TRANSPORT_REASSEMBLY
	default y
	help
	  Will reassemble downlink LoRaWAN messages together to allow for messages larger than a
	  single message to be received, otherwise will support messages up to a single packet in
	  size.

menuconfig MCUMGR_TRANSPORT_LORAWAN_POLL_FOR_DATA
	bool "Send empty packet if partial packet received"
	depends on MCUMGR_TRANSPORT_LORAWAN_REASSEMBLY
	default y
	help
	  Will send an empty packet if a partial (fragmented) message has been received from the
	  server, this will allow the next packet to be received without waiting for next
	  transmission window.

	  Note: this requires a dedicated thread in order to prevent blocking the system workqueue.

	  Stack size of the thread that will poll for empty additional packets when a partial
	  frame is received.
