RemoteBlaBla is a Pybricks program used to control LEGO's PoweredUp Hubs and Motors with the LEGO Remote Handset, with no need for programming.
This App, RemoteBlaBla App, is used to configure the RemoteBlaBla program running in the hub, defining hub's behavior in response to remote control actions.
The configuration is saved in the Hub so that you can play with it later. No need to use the phone to control the hub, you control the hub with LEGO Remote.
Later, you can go back to the App to change the configuration.

To use RemoteBlaBla you first need to install Pybricks (https://pybricks.com) in your hub. Then, in RemoteBlaBla App Hubs screen, you can list available hubs, and you will be able to install the RemoteBlaBla program in the hub.

After configuring your hub, you can play with your hub and motors, without a phone:

1) Connect the hub by clicking the hub green button. You will get a blinking blue light, telling that Pybricks has started. Click again, to start RemoteBlaBla. The hub light will blink in white. This tells you that you should connect the remote handset. Connect the remote.

2) Each button set, ({+/-/red} buttons on the remote), controls a set of motors, as you defined in this App. Pressing plus will actuate the motor in one direction. Pressing minus will actuate in the opposite direction. The red button can be used to stop the motor (if the BLA mode allows the motors to spin with no button pressed).

3) To stop RemoteBlaBla with the remote, press the remote green button for about 1.5s (the remote light should blink 4 times). Now you are back in Pybricks stand-by mode, so you can connect RemoteBlaBla App to the hub and reconfigure.

4) To stop RemoteBlaBla in the hub, press the hub green button for about 1.5s.

5) You can go back to RemoteBlaBla App, connect to the hub and change its configuration as many times as you need.
