[Ember Zigbee]Zigbee3.0裝置入網提速

針對Simplicity Studio 4，EmberZNet協定棧Zigbee3.0裝置入網時間提速

Platform：Simplicity Studio 4、EmberZNet SDK 6.4.1.0

1.設定開始掃描狀态

由于zigbee3.0擁有4種入網方式，

enum {
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_NONE                         = 0x00,
  // These next two states are only run if explicitly configured to do so
  // See emAfPluginNetworkSteeringSetConfiguredKey()
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_CONFIGURED      = 0x01,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_CONFIGURED    = 0x02,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_INSTALL_CODE    = 0x03,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_INSTALL_CODE  = 0x04,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_CENTRALIZED     = 0x05,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_CENTRALIZED   = 0x06,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_DISTRIBUTED     = 0x07,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_DISTRIBUTED   = 0x08,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_FINISHED                = 0x09,

  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_UPDATE_TCLK                  = 0x10,
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_VERIFY_TCLK                  = 0x20,
};
           

裝置上電會按照這個四種方式輪詢掃描入網，而一般裝置都采用集中式入網（CENTRALIZED）方式入網，故首先設定開始掃描方式為集中式，協定棧預設設定為EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_INSTALL_CODE，即二維碼優先碼信道掃描方式

emAfPluginNetworkSteeringState = gUseConfiguredKey
                                       ? EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_CONFIGURED
                                       : EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_PRIMARY_INSTALL_CODE;
           

修改emAfPluginNetworkSteeringState = EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_CENTRALIZED;

2.修改最後掃描狀态

協定棧預設為

#define LAST_JOINING_STATE \
  EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_DISTRIBUTED
           

修改為#define LAST_JOINING_STATE \

    EMBER_AF_PLUGIN_NETWORK_STEERING_STATE_SCAN_SECONDARY_CENTRALIZED
