Mobile app interface for controlling a mecanum wheel drivetrain IOT device using both BLoC and Cubit for State Management. The app communicates with the target IOT device via bluetooth or Wifi. In bluetooth mode, data is sent directly to the target IOT device via bluetooth channels after a successful bluetooth connection. In Wifi mode, data is sent to a local MQTT server that we have set up here in Innov8 Hub. Using the publish/subscribe model of communication, messages are published to specific topics which the drivetrain subscribes to and adjusts its movement with respect to these messages.
