Abstract

The invention provides a VoIP-PSTN hybrid intelligent terminal based on a Bluetooth and a working method thereof. The intelligent terminal comprises an ARM main processor, a PSTN module and a Bluetooth module. The Bluetooth module is formed by integrating a Bluetooth radio frequency part and a microprocessor, and the ARM processor carries out communication with the Bluetooth module through a Uart interface and controls the communication between the Bluetooth module and a mobile phone Bluetooth module by sending a command so as to realize the transmission of speech and data between an intelligent phone and a mobile phone. The speech transmission is realized by the hands-free section of a Bluetooth technique, the file transmission is realized by the file transmission section of the Bluetooth technique, and the reception and sending of short messages are realized by an AT instruction. The invention provides convenience for a user to make a call and reduces radiation of the mobile phone to body, new short messages in the mobile phone can be checked on the intelligent phone without turning on the mobile phone, and synchronously the short messages of the mobile phone can be sent by the intelligent phone.

Description

technical field [0001] The invention relates to a smart phone, especially a bluetooth-based smart phone, and belongs to the technical field of bluetooth. Background technique [0002] With the continuous development of communication technology, mobile phones are used more and more widely, but there are wireless radiation problems in mobile phones. The maximum transmission power of a GSM mobile phone is 2W (33dBm). Some people often use mobile phones with high frequency due to work needs. Being exposed to strong electromagnetic waves for a long time, especially when the mobile phone is on a call, the radiation is particularly large. Frequently holding the mobile phone close to the ear to answer the phone will undoubtedly bring radiation hazards to the human body. In order to reduce the hazards of mobile phone radiation, many communication product companies have produced Bluetooth headsets using Bluetooth technology. The main purpose is to use short-range wireless communicatio...
