The Bluetooth idea started with a practical driving problem: physical controls could reduce the need to handle or look at the phone.
Prompt nineteen did not yet make buttons perform actions. It built the device layer first. Drivers could scan, connect, disconnect, forget and rename compatible remotes, while the app normalized different kinds of Bluetooth input into a common event containing the device, button, event type and timestamp.
A Learn Device mode was included so unfamiliar remotes could be diagnosed by showing the last raw and normalized event. Multiple devices could be remembered, but one active control device would be clearly identified. Reconnection was allowed; endless background scanning was not.
Most importantly, a connected device still did nothing until the user explicitly mapped its buttons. We separated ‘I received a physical input’ from ‘I am authorized to perform this action.’ That distinction became crucial in the next stages.
