1. Overview

zstack-constants exports all constants used in TI's zigbee z-stack.

2. Installation

$ npm install zstack-constants --save

3. Usage

To use a constant, just access it within the correct layer, namespace, and the property name. Here is a quick example to access the constant ACK_REQUEST of AF options:

var ZSC = require('zstack-constants');

// Access properties under root space  
console.log(ZSC.BEACON_MAX_DEPTH);          // 15
console.log(ZSC.DEF_NWK_RADIUS);            // 30
console.log(ZSC.AF_DEFAULT_RADIUS);         // 30

// Access constants in config and cmdStatus namespaces  
console.log(ZSC.config.NWK_MAX_DEVICES);    // 21
console.log(ZSC.cmdStatus.BUFFER_FULL);     // 17

// Access constants in options and interpanCtl namespaces under AF layer
console.log(ZSC.AF.options.ACK_REQUEST);    // 16
console.log(ZSC.AF.interpanCtl.SET);        // 1

// Access constants in adcResolution and gpioOperation namespaces under SYS layer
console.log(ZSC.SYS.adcResolution.BIT_10);  // 1
console.log(ZSC.SYS.gpioOperation.TOGGLE);  // 4

// Access constants in stackProfileId and deviceLogicalType namespaces under ZDO layer
console.log(ZSC.ZDO.stackProfileId.ZIGBEEPRO_PROFILE);  // 2
console.log(ZSC.ZDO.deviceLogicalType.ROUTER);          // 1

4. Status Getter

zstack-constants provides you with an API getStatus() to get the defintion of a status code. This may help in showing error message when a bad status code coming back.

---

.getStatus(code)

Get the definition of a status code. This method accepts an input code in string or in number, and it will return an object like { key: 'BUFFER_FULL', value: 17 } to tell the status definition. This method will return undefined if the given status code is not found.

Arguments:

1. code (Number | String): Status code in string or in number.

Returns:

• (Object): Status definition

Examples:

var ZSC = require('zstack-constants');

ZSC.getStatus(16);              // { key: 'MEM_ERROR', value: 16 }
ZSC.getStatus(183);             // { key: 'APS_NO_ACK', value: 183 }
ZSC.getStatus('APS_NO_ACK');    // { key: 'APS_NO_ACK', value: 183 }

AF	The exported namespaces of AF layer include cmdStatus, addressMode, interpanCtl, networkLatencyReq, and options.
MAC	The exported namespaces of MAC layer include cmdStatus, capabInfoMask, logicalChannels, channelMask, securityLevel, addressMode, scanDuration, assocStatus, channelPage, txOpt, commReason, disassocReason, keyIdMode, beaconOrder, scanType, frontEndMode, and pidAttr.
SYS	The exported namespaces of SYS layer include cmdStatus, nvItemIds, resetType, capabilities, osalTimerEvent, adcChannels, adcResolution, gpioOperation, sysStkTune, resetReason, nvItemInitStatus, and nvItemDeleteStatus.
UTIL	The exported namespaces of UTIL layer include cmdStatus, devStates, channelMask, securityLevel, addressMode, getNvStatus, subsystemId, deviceType, keyEvent, keyValue, ledMode, ledNum, subsAction, ackPendingOption, and nodeRelation.
ZDO	The exported namespaces of ZDO layer include cmdStatus, capabInfoMask, devStates, logicalChannels, channelMask, scanDuration, status, initDev, serverCapability, appDevVer, stackProfileId, deviceLogicalType, addrReqType, leaveAndRemoveChild, leaveIndRequest, leaveIndRemove, leaveIndRejoin, and descCapability.
