step S10, when the control device is started, the Bluetooth module and the 2.4G module are controlled to start to enter a connection mode;
the Bluetooth and 2.4G dual-module automatic connection control method provided by the embodiment of the invention is mainly applied to wireless connection equipment and is used for automatically selecting which mode is adopted to establish wireless connection. The method for controlling the automatic connection between the bluetooth module and the 2.4G dual-module provided by the embodiment is applied to a gamepad, and is used for controlling the gamepad to be connected with a controlled terminal by using the bluetooth module or wirelessly connected with the controlled terminal by using the 2.4G module. Namely, the control device is a game PAD, and the controlled device can be a mobile phone, a PAD, a smart television, and the like. Specifically, when the game pad starts the bluetooth module and the 2.4G module to work simultaneously, the 2.4G module is firstly considered to be adopted for wireless connection due to selection of energy consumption; when the 2.4G module can not be in wireless connection, the Bluetooth module is selected, and meanwhile, in order to avoid crosstalk between the Bluetooth module and the Bluetooth module, when a connection mode is determined to be adopted, the work of the other module is automatically closed.
Specifically, the gamepad is provided with a bluetooth module and a 2.4G module, and when the gamepad is started or reset, the bluetooth module and the 2.4G module both enter an initialization program and enter a connection mode. The existing connection protocol is adopted for the connection process of the bluetooth module to establish the bluetooth connection, and the connection process of the 2.4G module needs to adopt the following mode.
Step S20, when the 2.4G module enters the connection mode, controlling the 2.4G module to perform frequency hopping operation on a preset frequency point according to a cycle of a first preset duration so as to receive a preset data packet broadcast by a receiver;
step S30, judging whether a receiver matched with the 2.4G module exists according to the received data packet;
step S40, when the receiver matched with the 2.4G module is determined to exist, sending a data command of agreeing to connection to the receiver; the receiver establishes frequency hopping time synchronization with the 2.4G module according to the data command;
step S50, after sending the data command of agreeing to connect, sending a preset inquiry command to the receiver;

At this time, the receiver broadcasts a predetermined data packet for the 2.4G module to receive and establish a connection. In this embodiment, the receiver broadcasting the data packet includes: after the receiver is powered on, frequency hopping operation is carried out on the preset frequency point at the period of the second preset duration, and the data packet is broadcasted at the current frequency point; the data packet comprises the identity identification information of the receiver, the state information of the connecting handle and the current game protocol mode; the judging whether a receiver matched with the 2.4G module exists according to the received data packet comprises the following steps: and determining whether a receiver matched with the 2.4G module exists according to the identification information in the data packet.
In this embodiment, the ID information is an ID of the receiver, and in a normal case, the receiver has a matching relationship with the 2.4G module, and the 2.4G module only establishes a connection with the receiver specified for matching, and can be identified by an ID number of the receiver. The state information of the connection handle refers to whether the receiver has established a connection with the handle, in this embodiment, one receiver may be connected to 1 gamepad, or may be connected to a plurality of gamepads, which is not further limited herein. In this embodiment, different games or different versions of the same game may have different game protocol modes, and a user may set the game protocol mode or automatically select a corresponding game protocol mode according to the currently running game; the receiver broadcasts the current game protocol mode of the receiver, and after the game handle end is connected with the receiver end, whether an instruction is sent to control the receiver to change the game protocol mode can be confirmed according to the current game protocol mode of the game handle end, so that the game protocol mode of the receiver end is matched with the game protocol mode of the game handle end.
In this embodiment, the number of the preset frequency points may be set according to actual needs, preferably, 16 frequency points are adopted here, that is, 16 channels, and the 16 channels are channels that avoid 2.4G signals such as bluetooth and wifi.

It should be noted that determining that there is no receiver matching the 2.4G module includes the case where there is no receiver matching the 2.4G module in the received data packet and no data packet is received.
When a receiver matched with the 2.4G module exists, a data command which agrees to connection is sent to the receiver, and the content of the data command can be set according to actual needs, such as the ID of a game handle, the game protocol mode of the target, the correction data of the frequency hopping synchronization time and the like, so that the receiver receives the data command to perform time synchronization correction, and the frequency hopping time of the receiver and the 2.4G module is kept consistent.

Specifically, the above embodiment explains the connection process under the condition that the 2.4G module can be normally connected, and the bluetooth module needs to be adopted to establish the bluetooth connection under the condition that the 2.4G module cannot be normally connected, and since the bluetooth module enters the bluetooth normal connection start when the gamepad is started, the normal bluetooth connection can be completed only by closing the 2.4G module. In this embodiment, the second control module is further configured to control to close the 2.4G module when it is determined that there is no receiver matching with the 2.4G module, or when response information of the receiver to the query command is not received.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
