Side-app can't call if the device doesn't request first.

[DotIN13]

In the map application I'm currently working on, this.call from side-app cannot be received in device-app unless this.request has been called for at least once in the device-app.

Please confirm if this is a bug.

Additionally, it seems that onInit (params) in BasePage get passed a string "undefined" by default. I believe this is not the desired behavior. A plain undefined might just work here.

Thanks in advance!

1. The current communication model is similar to browser to server, where device-app is the browser and side-service is the server. If there is no communication link established, side-service cannot send to device-app. If you really want to do this, you can send a request from app.js onCreate. Or use the internal method, which may not be stable.

2. I tested and did not receive a string in the onInit method of the page module.

@htoooth I used the approach to send a request from app.js, however, it doesn't work every time I run the app, Maybe 50% of the time, I get this handshaking error on start, and the connection is never works after that until I restart the app and I get a chance to not showing the error again.

1. app.js file

2. Error showing on app creation

note that I also tried the internal command and the same behavior happens
