The provided wireless network (as described in step S3063), if the electronic device 43 is connected to the wireless network provided by the pairing information 210 but cannot establish a connection with the wireless projection device 2, indicating that there is a problem with the system, the execution of the steps is stopped. If the electronic device 43 is not connected to the wireless network provided by the pairing information 210, the service setting identifier 219 in the pairing information 210 is used to automatically assist the electronic device 32 to switch to the wireless network provided by the wireless projection device 2, and then execute Step S303 is to complete the subsequent wireless projection step.
由上述說明可知,區域網路之內部人員並不需要以手動方式先中斷與區域網路連結,再切換至無線投影裝置的無線存取點,便可以和無線投影裝置建立連結,因此不會造成會議時間的浪費。 As can be seen from the above description, the internal personnel of the regional network do not need to manually disconnect the regional network connection, and then switch to the wireless access point of the wireless projection device, so that the wireless projection device can be connected, so Waste of meeting time.
