A standardized profile is the "Serial Port Profile" (SPP). It is used for wireless
transmission of serial interface data such as RS-232 or RS-485.
The "Service Discovery Profile" (SDP) supported by all Bluetooth
allows a device to discover which devices are in range and to identify supported
profiles. Devices can broadcast which functions are supported by encoding such
functions as a so-called "Class of Device" (CoD) and by sharing that with other
devices. The CoD then makes it possible to look for devices with specific
functionality.

In addition to the CoD, all devices have a MAC ID that is used to uniquely
identify the device. Many devices also allow you to choose and save a specific
name for the device. This name is then also be queried wirelessly.
In addition to standardized profiles, industrial devices sometimes also use
proprietary profiles to meet specific requirements, e.g. in terms of reliability.

Security

Compatibility, connectivity and the security of radio communication are high
priorities for Bluetooth
applications that the technology uses, configurations can arise where devices are
unable to communicate with each other because of the different security
mechanisms implemented. This can affect devices, for example, that have no
configuration options for reasons of cost or devices that do not allow direct user
interaction based on their design.
