and under the condition that the main board does not occupy the wireless signal resource, controlling the wireless communication module to provide wireless signals to the SOC of the second equipment 200 in the exclusive mode.
In the exclusive mode, the wireless communication module provides wireless signals to the SOC, and the wireless communication module does not provide wireless signals to the motherboard.
In this embodiment, if the first device 100 does not occupy wireless signal resources, that is, the first device 100 does not need to use network connection, the wireless signal may also be provided to the second device 200 by the wireless communication module in a sharing manner.
In some embodiments, the exclusive mode specifically includes:
the processor of the first device controls the wireless communication module to be switched from being connected with the main board to being connected with the first communication interface through a change-over switch;
or the processor of the first device controls the wireless communication module to be connected with the first communication interface through a bypass in the processor.
As shown in fig. 1, specifically, the wireless communication module may be controlled to be connected to the second combination by the above-described change-over switch SW, and disconnected from the first device 100.
As shown in fig. 3, in the present embodiment, the wireless signal provided by the wireless communication module may also be transmitted to the first communication interface through a bypass in the CPU under the control of the CPU of the first device 100, so that the wireless communication module provides the wireless signal only to the second device 200, specifically, the wireless signal provided by the wireless communication module may be converted into a USB signal by the SDIO (Secure Digital Input and Output Card, secure digital input output) signal by the CPU of the first device 100 and then provided to the second device 200 through the USB sub-interface.
The foregoing is merely a specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the disclosure, and it should be covered in the protection scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
