what is bluetooth map version

Bluetooth MAP (Message Access Profile) is a Bluetooth profile that allows devices to exchange messages, especially tailored for the automotive hands-free use case where an infotainment system can access text messages and email data on a paired device. The Bluetooth MAP version refers to the version of this profile that is being used. By default, the highest version of Bluetooth MAP is 1.4. However, some devices may have a setting in their developer options to change the Bluetooth MAP version, which can affect the type of control and information that is sent via Bluetooth, such as album, track, and other metadata.
