Using a vehicle's on-board diagnostic (obd) system for audio reminders

An on-board diagnostic (OBD) interface to couple to a diagnostic port of a vehicle, the OBD interface comprising:

• a communication interface;
• a memory storing instructions;
• and
• one or more processors to execute the instructions to:
• receive, by the communication interface via a wireless network, a message comprising text from a user device associated with a user;
• convert the text into an audio file that corresponds to an audio reminder;
• detect a key-on event for the vehicle;
• establish, responsive to the key-on event, a first wireless connection to a speaker device located in the vehicle;
• send, by the communication interface via the first wireless connection, a notification to the speaker device that the audio reminder is pending;
• terminate, after the notification is sent, the first wireless connection;
• establish a second wireless connection to the speaker device;
• and
• transfer, by the communication interface via the second wireless connection, the audio file to the speaker device.

A non-transitory, computer-readable storage medium storing instructions executable by a processor of a computational device of an on-board diagnostic (OBD) interface coupled to a diagnostic port of a vehicle, which when executed cause the computational device to:

• receive, via a wireless network, a message comprising text from a user device associated with a user;
• convert the text into an audio file that corresponds to an audio reminder;
• detect a key-on event for the vehicle;
• establish, responsive to the key-on event, a first wireless connection to a speaker device located in the vehicle;
• send, via the first wireless connection, a notification to the speaker device that the audio reminder is pending;
• terminate, after the notification is sent, the first wireless connection;
• establish a second wireless connection to the speaker device;
• and
• transfer, via the second wireless connection, the audio file to the speaker device.
