Abstract

The invention discloses a bluetooth module for a mobile terminal, which aims to solve the problems of electromagnetic interference and electromagnetic compatibility when bluetooth chips are integrated into a module in the mobile terminal. The problems of electromagnetic interference and electromagnetic compatibility are solved or reduced through the reasonable sorting to pins. The bluetooth module can be widely applied to mobile terminals.

Description

technical field [0001] The invention belongs to the hardware technology of mobile communication and wireless transmission, in particular to a bluetooth transmission hardware technology. Background technique [0002] Most of the existing hardware architectures of mobile terminals are to directly connect various components to the main board, and the Bluetooth (BlueTooth) chip is also directly arranged on the main board of the mobile terminal. The disadvantage of this setting scheme is that after connecting the Bluetooth chip to the motherboard, an overall test is required. If there is a problem in the test and modification is required, a comprehensive modification of the motherboard is required. When multiple components are installed on the motherboard of the mobile terminal (this is a common situation), repeated testing of multiple modules will lead to a long development cycle and high development costs. [0003] The Bluetooth chip and related circuits are integrated into a ...
