Major Classes

This module provides you with Bridge and Endpoint classes.

Bridge class brings you a ZigBee Server with network managing facilities, i.e., start/stop the Server, permit device joining, find a joined endpoint. This document uses bridge to denote the instance of this class.
Endpoint is the class for creating a software endpoint to represent the remote or local endpoint at server-side. This document uses ep to denote the instance of this class. You can invoke methods on an ep to operate the endpoint.

Bridge Class

Exposed by require('zigbee-bridge')

new Bridge(path[, opts])

Create a new instance of the Bridge class. The created instance is a ZigBee gateway that runs with node.js.

Arguments:

path (String): A string that refers to system path of the serial port connecting to your ZNP (CC253X), e.g., '/dev/ttyUSB0'.
opts (Object): This value-object has three properties sp, net and dbPath to configure the serial port, zigbee network settings and database file path.
- sp (Object): An optional object to configure the seiralport. Default is { baudrate: 115200, rtscts: true }.
- net (Object): An object to configure the network settings, and all properties in this object are optional. The descriptions are shown in the following table.
- dbPath (String): Set database file path, default is __dirname + '/database/dev.db'.

Property	Type	Mandatory	Description	Default value
panId	Number	Optional	Identify the ZigBee PAN. This id should be a value between 0 and 0x3FFF. You can also set it to 0xFFFF to let ZNP choose a random PAN-ID on its own.	0xFFFF
channelList	Array	Optional	Pick possible channels for your ZNP to start a PAN with. If only a single channel is given, ZNP will start a PAN with the channel you’ve picked.	[ 11 ]
precfgkey	Array	Optional	This is for securing and un-securing packets. It must be an array with 16 uint8 integers.	[ 0x01, 0x03, 0x05, 0x07, 0x09, 0x0B, 0x0D, 0x0F, 0x00, 0x02, 0x04, 0x06, 0x08, 0x0A, 0x0C, 0x0D ]
precfgkeysEnable	Boolean	Optional	To distribute the security key to all devices in the network or not.	true
startoptClearState	Boolean	Optional	If this option is set, the device will clear its previous network state. This is typically used during application development.	false

Returns:

(Object): bridge

Examples:

const Bridge = require('zigbee-bridge');

const bridge = new Bridge('/dev/ttyUSB0', {
  sp: {
    baudrate: 115200,
    rtscts: true
  },
  net: {
    panId: 0x1234,
    channelList: [12, 14], // pick CH12 and CH14
    precfgkey: [
      0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
      0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f
    ],
    precfgkeysEnable: true
  }
});

.start()

Connect to the ZNP and start bridge.

Returns:

(Promise): promise

Examples:

// promise style
bridge.start()
  .then(() => console.log('bridge is now running.'));

.stop()

Disconnect from the ZNP and stop bridge.

Returns:

(Promise): promise

Examples:

bridge.stop()
  .then(() => console.log('bridge is stopped.'));

.reset(mode)

Reset the ZNP.

Arguments:

mode (String Number): Set to 'hard' or 0 to trigger the hardware reset (SoC resets), and set to 'soft' or 1 to trigger the software reset (zstack resets).

Returns:

(Promise): promise

Examples:

// hard reset
bridge.reset(0)
  .then(() => console.log('reset successfully.'));

// soft reset
bridge.reset('soft')
  .then(() => console.log('reset successfully.'));

.permitJoin(time[, type])

Allow or disallow devices to join the network. A permitJoining event will be fired every tick of countdown (per second) when bridge is allowing device to join its network.

Arguments:

time (Number): Time in seconds for bridge to allow devices to join the network. This property accepts a value ranging from 0 to 255. Given with 0 can immediately close the admission and given with 255 will always allow devices to join in.

type (String Number): Set it to 'coord' or 0 to let devices join the network through the coordinator, and set it to 'all' or 1 to let devices join the network through the coordinator or routers. The default value is 'all'.

Returns:

(Promise): promise

Examples:

bridge.on('permitJoining', (joinTimeLeft) => {
  console.log(joinTimeLeft);
});

// default is allow devices to join coordinator or routers
bridge.permitJoin(60)
  .then(() => console.log('ZNP is now allowing devices to join the network for 60 seconds.'));

// allow devices only to join coordinator
bridge.permitJoin(60, 'coord');

.info()

Returns bridge information.

Arguments:

none

Returns:

(Object): An object that contains information about the server. Properties in this object are given in the following table.

Property	Type	Description
enabled	Boolean	Server is up(`true`) or down(`false`)
net	Object	Network information, `{ state, channel, panId, extPanId, ieeeAddr, nwkAddr }`
startTime	Number	Unix Time (secs from 1970/1/1)
joinTimeLeft	Number	How many seconds left for allowing devices to join the Network

}
*/

.mount(zApp, callback)

Mounts a zigbee application zApp that will be registered to the coordinator as a local endpoint, where zApp is an instance created by the ZCL framework zive. With zive, all you have to do is to plan your clusters well and zive itself will handle all ZCL messages for you.

Arguments:

callback (Function): function (err, epId) { }. When zApp mounts to coordinator successfully, bridge will return you a registered endpoint id. This epId is something that helps bridge route all messages going to the zApp.

Returns:

(Promise): promise

Examples:

const myZbApp = require('./lib/myZbApp.js'); // myZbApp is an instance of Zive

bridge.mount(myZbApp, (err, epId) => {
  if (!err) {
