function switch key arrange in pairs or groups this button press simultaneously produce a switching signal, switching this with this switching signal has ray mode and this wireless mode, and this alleged handoff functionality key may further be a function key (Fn_key) set on this keyboard 21.Another is implemented aspect and refers to Fig. 5 for this external bluetooth selecting arrangement 1 is provided with a mode switch element 17(), be subject to this switching signal of triggering for generating to order about this micro-control unit 14 in this mode switch element 17 and enable this wireless communication module 13 or this first connectivity port 11.In selecting this to have after ray mode, this external bluetooth selecting arrangement 1 enables this first connectivity port 11, the command signal that this load module 2 is exported is passed to this first information device 3 through this first connectivity port 11, if select this wireless mode to perform step four, utilize this first switch means to determine this Array selection code, and read this corresponding device identification code and this device authorization code with this micro-control unit 14, the line with these wireless communication module 13 foundation with corresponding this second massaging device 4 of this Array selection code.Illustrate further, this first switch means can be this external bluetooth selecting arrangement 1 and is provided with a selected cell 18, makes this selected cell 18 be subject to triggering for generating one to select this Array selection code of signal deciding.Read corresponding this device identification code and this device authorization code by this Array selection code, and then connect with this corresponding second massaging device 4, the command signal that this load module 2 transmits is passed on this second massaging device 4 by this wireless communication module 13.In addition, this external bluetooth selecting arrangement 1 has one and is connected with this micro-control unit 14 and has under ray mode and make this micro-control unit 14 enable the start-up performance unit 19 of this first connectivity port 11 in this with one the 3rd switch means, and this alleged start-up performance unit 19 may further be a switch, the operational means that the 3rd switch means can the application of force be pressed this startup supply unit 19.
And refer to Fig. 6, in embodiment, mention that this load module 2 can be this keyboard 21 or for this mouse 22, and this command signal that this keyboard 21 is exported with this mouse 22 is not identical, therefore step 1 of the present invention also comprises following sub-step: a. and judges load module S11; B. converted command signal S12.Illustrate, in the time that this load module 2 connects this first connectivity port 11, this external bluetooth selecting arrangement 1 judges that taking this micro-control unit 14 this load module 2 being connected with this first connectivity port 11 is as this mouse 22 or this keyboard 21, after having judged, just enter next step, utilize this micro-control unit 14 to change this load module 2 this command signal of inputting into a general format input instruction.Further, for reaching above-mentioned purpose, this micro-control unit 14 may further be a chip with USB OTG function.
Refer to Fig. 7, this step 3 of the present invention also includes following sub-step: a. and detects first information device S33; B. change connection mode S34.Illustrate, in detecting first information device S33 step, this external bluetooth selecting arrangement 1 utilizes this micro-control unit 14 to detect the electrical connection signal that this second connectivity port 12 is connected with this first information device 3, this micro-control unit 14 detects when this electrical connection signal exists preferentially has ray mode to implement with this, if when this micro-control unit 14 can't detect this electrical connection signal, this micro-control unit 14 is implemented with this wireless mode.That is to say, before determining with this second switch means that in this step 3 this has ray mode or this wireless mode, this external bluetooth selecting arrangement 1 first judges whether this first information device 3 has set up line, give tacit consent to if having with this and have ray mode and this first information device 3 lines, if without switching on this wireless mode.And refer to Fig. 8, the present invention is in determining have ray mode or wireless mode (step 3) afterwards, can further comprise step 5, set up many targets device step S5, determine after this wireless mode, can again restart this many targets detecting pattern, again seek this second massaging device 4 within the scope of these wireless communication module 13 efficient communications, obtain this device identification code and this device authorization code of this second massaging device 4 and set up one and be this Array selection code of corresponding relation with this device identification code and this device authorization code, for this external bluetooth selecting arrangement 1 line.
In sum, the multi-object switched transmission method of the external bluetooth selecting arrangement of the present invention, switch that at least one load module has ray mode and a first information device line with one or with one of them line of a wireless mode and at least two second massaging devices by an external bluetooth selecting arrangement, this switched transmission method includes an apparatus for establishing connection step, one sets many targets device step, one determines make decision the second massaging device step of line of wired line or radio connecting step and a wireless mode, by the switching of this external bluetooth selecting arrangement, this load module is obtained is applied on this first information device and these the second massaging devices simultaneously, and can set up on demand and the line of corresponding massaging device.
Below the present invention is described in detail, but as described above is only a preferred embodiment of the present invention, when not limiting scope of the invention process with this, be that all equalizations of doing according to the claims in the present invention change and modify, all should still belong in patent covering scope of the present invention.
