Identify controller through reports
In order to be marketed in different countries, devices with wireless communications have to pass certification processes to ensure that they do not interfere with other devices.
Since Bluetooth is a wireless technology, if the device has already been certified, it is sometimes possible to obtain the certification reports. These reports may contain very relevant information for our analysis such as pictures of the printed circuit boards, transmitting and receiving power metrics, Bluetooth driver models…
In some cases, this search may require the use of search engines or the study of the web pages of the main regulatory agencies but in other cases, the certification itself requires the device to be marked with a unique identifier.
An example of the latter would be the ‘FCC ID’, a visible identifier that has to be marked on devices certified by the ‘FCC’. On a device tested, the text
FCC ID: A3LSMR177R is found. After a search, the device report is found at https://fcc.report/FCC-ID/A3LSMR177R. In the report for this FCC identifier we can find pictures and even the Bluetooth driver of the device.
Telecommunications regulatory agencies
Some of the telecommunications regulatory agencies that may contain reports on wireless communications devices are listed in the table below:
