Embodiment 1
[0044] figure 1Shown is the communication device 1 provided by Embodiment 1 of the present invention. The Bluetooth chip 14 of the communication device 1 is integrated in a baseband chip, and the upper layer processing module of the Bluetooth chip 14 is a Bluetooth host 15 . Described communication device 1 also comprises data transceiving interface 16, and data transceiving interface 16 among the present embodiment is made up of a UART data transceiving interface 161 and a USB data transceiving interface 162, and their corresponding data processing modules 17 are UART data processing modules respectively. Module 171 and USB data processing module 172. Usually, a communication device (such as a mobile phone) has a tail jack for charging, debugging, data transmission, software upgrade, etc. of the communication device. The UART data transceiving interface 161 and the USB data transceiving interface 162 in this embodiment are usually implemented through the tail socket of the c...
Embodiment 2
[0057] Such as Figure 4 As shown, it is a schematic structural diagram of a communication device 3 according to Embodiment 2 of the present invention. The communication device 3 includes: a Bluetooth chip 14, a Bluetooth host 15, a data transceiver interface 16 and a corresponding data processing module 17, a first switch 11, a second A switch 12 , a test control module 13 , a format conversion module 19 and a third switch 20 . It can be seen that the difference from the communication device 1 in Embodiment 1 is that a format conversion module 19 and a third switch 20 connected thereto are added between the first switch 11 and the second switch 12 . It can be seen that the first switch in Embodiment 1 can directly control the connection between the target test chip and the data transceiver interface; while the first switch in this embodiment needs to be indirectly controlled by the format conversion module and the third switch. Controlling the connection between the target t...
Embodiment 3
[0067] Such as Figure 7 As shown, it is a schematic structural diagram of a communication device 4 according to Embodiment 3 of the present invention, including: a Bluetooth chip 14, a Bluetooth host 15, a data transceiver interface 16 and its corresponding data processing module 17, a first switch 11, a second switch 12, Test the control module 13 , the format conversion module 19 and the third switch 20 . It can be seen that this embodiment is an implementation mode after combining Embodiment 1 and Embodiment 2, that is, the Bluetooth chip 14 can be directly connected to the data transceiver interface 16, and can also communicate with the data transceiver interface 19 via the format conversion module 19. The interface 16 is indirectly connected. Specifically, when the bluetooth chip 14 and the test equipment 2 send and receive commands, instructions or data formats that are the same, the first switch 11 is controlled to connect the node a to the node d', and then the secon...
