Using Unity 2019.4.23

use your own TCP/UDP sender...

if you receive an anchor, call ImportAnchor()...

private void ExportAnchor(string anchorId, WorldAnchor transferAnchor) {
   byte[] serializedWorldAnchor = new byte[0];          
   void OnExportDataAvailable(byte[] data) {             
      //send to other h2             
      AppendBytes(ref serializedWorldAnchor, data);         
   }          
   void OnExportComplete(SerializationCompletionReason reason) {
      if (reason == SerializationCompletionReason.Succeeded) {
         //... send serializedWorldAnchor over TCP or UDP
      }
   }
   try {            
      WorldAnchorTransferBatch transferBatch = new WorldAnchorTransferBatch();
      transferBatch.AddWorldAnchor(anchorId, transferAnchor);    
      WorldAnchorTransferBatch.ExportAsync(transferBatch, OnExportDataAvailable, OnExportComplete); 
   } catch (Exception e) {}
}
private void ImportAnchor(byte[] importedData) {      
   try {             
      void OnImportComplete(SerializationCompletionReason reason, WorldAnchorTransferBatch importedBatch)
      {             
         if (reason == SerializationCompletionReason.Succeeded) {
		    string[] ids = importedBatch.GetAllIds();
			foreach (string id in ids) {
			   GameObject importedObject = CreateOrUpdateAnchorObject(prefab, id);
			   importedBatch.LockObject(id, importedObject);
            }                 
         }
	  }
	  
	  WorldAnchorTransferBatch.ImportAsync(importedData, OnImportComplete);
   }
}
