Member Function Documentation

◆ addWiFiManagerParameter()

void EnigmaIOTNodeClass::addWiFiManagerParameter ( AsyncWiFiManagerParameter * p )

inline

Adds a parameter to configuration portal.

Parameters

p	Configuration parameter

Definition at line 735 of file EnigmaIOTNode.h.

◆ begin()

void EnigmaIOTNodeClass::begin	(	Comms_halClass *	comm,
		uint8_t *	gateway = `NULL`,
		uint8_t *	networkKey = `NULL`,
		bool	useCounter = `true`,
		bool	sleepy = `true`
	)

Initalizes communication basic data and starts node registration.

Parameters

comm	Physical layer to be used on this node network
gateway	Gateway address
networkKey	Network key to protect shared key agreement
useCounter	Indicates if a counter has to be added to every message data to check message sequence. `true` by default
sleepy	Indicates if this node changes to low energy mode (sleep mode) after sending a data message. `true` by default

This condition is signalled to Gateway during registration so that downlink messages are managed diferently. On non sleepy nodes a downlink data message can be sent on any moment as node will be always awake. But for nodes that sleep, normally those that are powered with batteries, downlink message will be queued on gateway and sent just after an uplink data message from node has been sent
