Detailed Description

template<class mesh_t = ESBMesh<ESBNetwork<RF24>, RF24>, class network_t = ESBNetwork<RF24>, class radio_t = RF24>
class ESBGateway< mesh_t, network_t, radio_t >

Template Parameters

mesh_t	The `mesh` object's type. Defaults to `RF24Mesh` for legacy behavior. This new abstraction is really meant for using the nRF52840 SoC as a drop-in replacement for the nRF24L01 radio. For more detail, see the nrf_to_nrf Arduino library.
network_t	The `network` object's type. Defaults to `RF24Network` for legacy behavior. This new abstraction is really meant for using the nRF52840 SoC as a drop-in replacement for the nRF24L01 radio. For more detail, see the nrf_to_nrf Arduino library.
radio_t	The `radio` object's type. Defaults to `RF24` for legacy behavior. This new abstraction is really meant for using the nRF52840 SoC as a drop-in replacement for the nRF24L01 radio. For more detail, see the nrf_to_nrf Arduino library.

Examples: RF24GatewayNode.cpp, RF24GatewayNodeInt.cpp, RF24Gateway_ncurses.cpp, and RF24Gateway_ncursesInt.cpp.

Member Function Documentation

◆ begin() [1/2]

template<class mesh_t , class network_t , class radio_t >

void ESBGateway< mesh_t, network_t, radio_t >::begin	(	uint8_t	nodeID = 0,
		uint8_t	channel = 97,
		rf24_datarate_e	data_rate = RF24_1MBPS )

Begin function for use with RF24Mesh (TUN interface)

Parameters

nodeID	The RF24Mesh nodeID to use
channel	The radio channel to use (1-127)
data_rate	The RF24 datarate to use (RF24_250KBPS, RF24_1MBPS, RF24_2MBPS)

gw.begin(); //Start the gateway using RF24Mesh, with nodeID 0 (Master)

uint8_t nodeID; gw.begin(nodeID); //Start the gateway using RF24Mesh, with nodeID 1 (Child node)

Definition at line 21 of file RF24Gateway.cpp.

◆ begin() [2/2]

template<class mesh_t , class network_t , class radio_t >

void ESBGateway< mesh_t, network_t, radio_t >::begin	(	uint16_t	address,
		uint8_t	channel = 97,
		rf24_datarate_e	data_rate = RF24_1MBPS,
		bool	meshEnable = 0,
		uint8_t	nodeID = 0 )

Begin function for use with a TAP (Ethernet) interface. RF24Mesh can be used for address assignment, but ARP will be used to perform the lookups.

Parameters

address	The RF24Network address to use
channel	The radio channel (0-127) to use
data_rate	The RF24 datarate to use (RF24_250KBPS, RF24_1MBPS, RF24_2MBPS)
meshEnable	Whether to use RF24Mesh for address assignment
nodeID	The RF24Mesh nodeID to use if meshEnable has been set to true

uint16_t address=00; gw.begin(address); //Start the gateway without using RF24Mesh, with RF24Network address 00 (Master)

uint16_t address=01; gw.begin(address); //Start the gateway without using RF24Mesh, with RF24Network address 01 (Child)

◆ setIP()

template<class mesh_t , class network_t , class radio_t >

int ESBGateway< mesh_t, network_t, radio_t >::setIP	(	char *	ip_addr,
		char *	mask )

Once the Gateway has been started via begin() , call setIP to configure the IP and subnet mask.

Parameters

ip_addr	A character array containing the numeric IP address ie: 192.168.1.1
mask	A character array containing the subnet mask ie: 255.255.255.0

Returns: -1 if failed, 0 on success

◆ update()

template<class mesh_t , class network_t , class radio_t >

void ESBGateway< mesh_t, network_t, radio_t >::update ( bool interrupts = 0 )

Calling update() keeps the network and mesh layers active and processing data. This needs to be called regularly.

gw.update();
if(network.available()){
 ...do something
}

Parameters

interrupts Set true if called from an interrupt handler & call poll() from the main loop or a thread.

Definition at line 322 of file RF24Gateway.cpp.

◆ poll()

template<class mesh_t , class network_t , class radio_t >

void ESBGateway< mesh_t, network_t, radio_t >::poll ( uint32_t waitDelay = 3 )

gw.poll(); needs to be called to handle incoming data from the network interface. The function will perform a delayed wait of max 3ms unless otherwise specified.

Parameters

waitDelay How long in milliseconds this function will wait for incoming data.

Definition at line 339 of file RF24Gateway.cpp.

◆ interrupts()

template<class mesh_t , class network_t , class radio_t >

void ESBGateway< mesh_t, network_t, radio_t >::interrupts ( bool enable = 1 )

When using interrupts (gwNodeInt, ncursesInt examples) users need to call this function to disable interrupts before accessing the radio and again to re-enable interrupts when complete

Parameters

enable 0 to disable interrupts and access the radio, 1 to re-enable

Definition at line 314 of file RF24Gateway.cpp.

◆ meshEnabled()

template<class mesh_t , class network_t , class radio_t >

bool ESBGateway< mesh_t, network_t, radio_t >::meshEnabled ( )
