method getAdapterInfo didn't work

[Lyfei]

ionic code:

this.bluetoothle.getAdapterInfo().then((r) => {
      console.log('getAdapterInfo success:' + JSON.stringify(r));
    }).catch((reason) => {
      console.log('getAdapterInfo error:' + reason);
    });

and neither log.

I found it didn't executed when I set breakpoint on android project. but other method worked, such 'initialize', 'isEnabled' android plugin code:

public boolean execute(String action, final JSONArray args, final CallbackContext callbackContext) throws JSONException {
    //Execute the specified action
    if ("initialize".equals(action)) {
      initializeAction(args, callbackContext);
    } else if ("enable".equals(action)) {
      enableAction(callbackContext);
    } else if ("getAdapterInfo".equals(action)) {
      getAdapterInfoAction(callbackContext);
    }
    ...

Are any errors being thrown on the Java side? There's not much there that could go wrong.
