Finding and Binding後如何unbind?

跟據例子代碼, 利用BDB Commissioning Modes 的 Finding and Binding後, 應該該怎樣做才可以unbind? 使end device 或 router 脫離 co-ordinator? 有代碼可以參考嗎? 謝謝

在finding and binding的情況下，unbind的動作是由End Device或Router要傳出調閱然後等待Co-ordinator回應而解除綁定。代碼例子如下：

//In End Device 及 Router中 
emberAfFillCommandIdentifyClusterIdentifyQueryRequest(identifyTime); // send out the query 

//In Co-ordinator 
EmberAfStatus emberAfIdentifyClusterServerCommandIdentifyQueryResponseCallback(uint16_t identifyTime) 
{ 
  // Handle unbind request from the device. 
}
