Step S201, by the duty of First Line range monitoring physical port and virtual port
The DTR(Data Terminal Ready of the physical port of First Line range monitoring wireless communication module and the virtual port of application processor, data terminal ready) signal and DSR (Data Set Ready, data ready) signal, transmits the DTR signal of physical port and virtual port and DSR signal mutually.For example: the DTR signal of the physical port that is wireless communication module by the DTR signal transmission of the virtual port of application processor, the DSR signal of the physical port that is wireless communication module by the DSR signal transmission of the virtual port of application processor, the DTR signal of the physical port of the virtual port that is application processor by the DTR signal transmission of wireless communication module, the DSR signal of the physical port of the virtual port that is application processor by the DSR signal transmission of wireless communication module.
Step S202, physical port detected and there are data waiting for transmission
Step S203, judgement physical port data waiting for transmission are AT instruction or communication data
Read the physical port data waiting for transmission of wireless communication module, judge that described data are AT instruction or communication data.
If step S204 AT instruction, is directly transferred to virtual port by the second thread by AT instruction
Thereby realize the transmission of AT instruction from the physical port of wireless communication module to the virtual port of application processor.
If step S205 communication data, carries out circular treatment by the second thread, until communication data is all transferred to virtual port
Call circular treatment transport communication data, can prevent data from overflow, guarantee the integrality of data.Thereby complete the transmission of communication data from the physical port of wireless communication module to the virtual port of application processor.
Step S206, virtual port detected and there are data waiting for transmission
Step S207, by the 3rd thread, described data are directly transferred to physical port
Now no matter data are AT instruction or communication data, are all directly transferred to physical port, by wireless communication module, are directly processed.Thereby completed the transmission of data from the virtual port of application processor to the physical port of wireless communication module.
The upgrade method of wireless communication module of the present invention, by a virtual port is set on application processor, between virtual port and the physical port of wireless communication module, set up communication thread, realize the data interaction between virtual port and physical port, completed the upgrading of wireless communication module.Thereby wireless communication module can directly be upgraded by physical port, to avoid communication module to carry out dismounting, escalation process is convenient and swift, has avoided disassembly process to damage the secondary of wireless communication module.
Referring to Fig. 3, upgrade-system one embodiment of wireless communication module of the present invention is proposed, described upgrade-system can be for terminal devices such as mobile phone, panel computers, comprise application processor 110, wireless communication module 130, setting unit 120 and upgrading unit 140, described wireless communication module 130 is welded on the hardware plate of terminal device, hardware plate is provided with the physical port of wireless communication module 130, wherein:
Setting unit 120, for virtual port being set on application processor 110, sets up the communication thread between described virtual port and the physical port of wireless communication module 130.Concrete:
