Zstack HA 1.22 Enddevice产品在实际使用中设备会出现掉网，掉网后一定的情况下会失去密钥甚至是恢复到出厂时的网络状态

把下面代码屏蔽下做测试
// Do a normal join to the network after certain times of rejoin retries
else if( AIB_apsUseInsecureJoin == true )
[
devStartMode = MODE_JOIN;
]

这个问题 我也遇到过。

我的做法是：
ZDApp_ProcessNetworkJoin()函数中  这段红色的代码 屏蔽
     else if(devStartMode == MODE_REJOIN)
      [
        if ( ZSTACK_END_DEVICE_BUILD )
        [
          devStartMode = MODE_REJOIN;
          _tmpRejoinState = true;
          _NIB.nwkState = NWK_INIT;

          if( prevDevState == DEV_NWK_SEC_REJOIN_CURR_CHANNEL )
          [
            runtimeChannel = MAX_CHANNELS_24GHZ;
            prevDevState = DEV_NWK_SEC_REJOIN_ALL_CHANNEL ;
          ]
          else if ( prevDevState == DEV_NWK_SEC_REJOIN_ALL_CHANNEL)
          [
            // Set the flag that will ask the device to do trust center network layer rejoin.
            //_NIB.nwkKeyLoaded = FALSE;
            //ZDApp_ResetNwkKey(); // Clear up the old network key.
          #ifdef DEBUG_REJOIN
            HalUARTWrite(0,"Don't clearing network keyn", sizeof("Don't clearing network keyn"));
          #endif            
            runtimeChannel = (uint32) (1L << _NIB.nwkLogicalChannel);
            prevDevState = DEV_NWK_TC_REJOIN_CURR_CHANNEL ;
          ]

应该就可以了

嗯 是的 我把那部分注释掉，然后把这一块的逻辑调整了一下，让终端设备即便掉网了，也是在本信道持续发送重连请求。
