The invention relates to a Bluetooth pairing code configuration method and system, a terminal, a server and a vehicle-mounted device. The Bluetooth pairing code configuration method is used in a Bluetooth pairing code process between a first electronic device and a second electronic device, each of the first electronic device and the second electronic device comprises a Bluetooth protocol operation module for operating based on a Bluetooth protocol stack, and the method comprises the following steps: obtaining identity identification data of the second electronic device; calculating the obtained identity identification data through a preset algorithm to obtain a Bluetooth pairing code; and transmitting the Bluetooth pairing code to the Bluetooth protocol operation module of the first electronic device or the Bluetooth protocol operation module of the second electronic device. By adoption of the Bluetooth pairing code configuration method and system provided by the invention, the Bluetooth pairing code can verify the identity and can be automatically input, so that the Bluetooth pairing is automatically performed.
