      Problem description: 

      In central role (simple_central). Calling "HCI_LE_SetHostChanClassificationCmd" in GAP_LINK_ESTABLISHED_EVENT causes a halAssertHandlerExt. To reproduce it, put the HCI_LE_SetHostChanClassificationCmd after the GAP_LINK_ESTABLISHED_EVENT(connect with the paired/bonded peripheral )

       

      case GAP_LINK_ESTABLISHED_EVENT:    
      {      
        uint16_t connHandle = ((gapEstLinkReqEvent_t*) pMsg)->connectionHandle;      
        uint8_t* pAddr = ((gapEstLinkReqEvent_t*) pMsg)->devAddr;      
        BLE_LOG_INT_TIME(0, BLE_LOG_MODULE_APP, "APP : ---- got GAP_LINK_ESTABLISHED_EVENT", 0);      
        HCI_LE_SetHostChanClassificationCmd(map);
      

      After further debugging it was found that from the link layer.
       
      The maximum number of control commands in queue per connection is capped at a certain amount. In case, the number of control commands in the queue exceed the designated maximum number, then there will a violation of the struct. Additional logic should be added to prevent the number of control commands to exceed the maximum number allowed.
