As shown in fig. 3, the method for implementing packet control based on bluetooth broadcast packet of the present invention includes the following steps:
step S1, it is monitored whether the remote controller has a key pressed.
In the invention, the remote controller is a Bluetooth broadcast remote controller, namely a remote controller which contains a Bluetooth chip or an RF chip and sends a Bluetooth broadcast packet in a Bluetooth broadcast mode, a grouping key is arranged on the remote controller, the grouping key can be a single key, and also comprises a plurality of key combinations which are grouped keys, and when a user presses the grouping key on the remote controller, the pressing of the grouping key is monitored.
Step S2, when it is monitored that the grouping key is pressed, if the continuous pressing time of the grouping key exceeds the preset grouping setting time threshold, the remote controller ID, the grouping identification and the grouping number are filled in the Bluetooth broadcast packet and sent out in the form of the Bluetooth broadcast packet, if the continuous pressing time of the grouping key accords with the preset short pressing time threshold, the remote controller ID, the control identification and the grouping number are filled in the Bluetooth broadcast packet and sent out in the form of the Bluetooth broadcast packet.

Preferably, in step S2, the bluetooth broadcast packets including the remote controller ID, the packet identification, and the packet number are continuously transmitted with the packet key being continuously pressed, so that the controlled device determines the completion of the packet by counting the number of the bluetooth broadcast packets. Specifically, after the duration time of the group key exceeds the preset group setting time, the remote controller ID, the group identifier, and the group number are filled in the bluetooth broadcast packet and transmitted in the form of the bluetooth broadcast packet, it is continuously determined whether the group key is kept pressed, if yes, the bluetooth broadcast packet including the remote controller ID, the group identifier, and the group number is transmitted again, and if not, the process returns to step S1 to continuously monitor whether the key is pressed.
Meanwhile, a short press time threshold value is preset in the system of the remote controller, when a user presses a grouping key and monitors that the time for the user to continuously press the grouping key (namely the time for the grouping key to be pressed and loosened) is within the preset short press time, a corresponding control identifier is generated, the ID of the remote controller is obtained, the ID of the remote controller, the control identifier and a grouping number are filled into a Bluetooth broadcast packet and are sent out in the form of the Bluetooth broadcast packet, and the control identifier refers to an identifier for carrying out conventional control and can be a key value or a specially defined identifier for realizing a control function.

Preferably, in step S2, if it is detected that the control key is pressed, the obtained remote ID, control identifier and packet number of the last packet key are filled in the bluetooth broadcast packet and sent out.
Step S3, when receiving the bluetooth broadcast packet, the controlled device parses the bluetooth broadcast packet.
Specifically, after the controlled device is powered on and various initialized parameters are started, scanning of the bluetooth broadcast packet is started, when the bluetooth broadcast signal is scanned, the bluetooth broadcast packet is obtained and analyzed, and if the bluetooth broadcast signal is not scanned, scanning is continued.

That is, a packet-limited time threshold for setting a time when the controlled device can accept the packet setting after being powered on is preset in the controlled device system, that is, the packet setting can be accepted only within the time, and the packet application is not accepted beyond the time. And when the Bluetooth broadcast packet is judged to contain the packet identifier according to the analyzed Bluetooth broadcast packet, judging whether the time for receiving the Bluetooth broadcast packet exceeds the preset packet limited time threshold, if not, receiving the packet setting, and acquiring and recording the ID and the packet number of the remote controller according to the analyzed Bluetooth broadcast packet.
The invention can effectively prevent the controlled equipment from being interfered to cause error grouping by limiting the controlled equipment to be executed in a certain time of power-on.
Preferably, the controlled device continuously receives the bluetooth broadcast packets, determines whether the number of times of receiving the grouped bluetooth broadcast packets is greater than or equal to a threshold of the number of bluetooth broadcast packets of a preset successful group within the group limited time threshold, and if so, determines that the grouping is successful, and stores the remote controller ID and the group number for determining whether the subsequently received broadcast packets are legal, that is, the controlled device will respond only when the remote controller ID and the group number in the transmitted bluetooth broadcast packets are consistent with the stored information.
Therefore, the invention continuously sends the Bluetooth broadcast packets after the remote controller triggers the packets, the controlled equipment can complete the packets only by detecting the Bluetooth broadcast packets containing the packet identifiers for a few times, and the reliability of the packet setting can be ensured.
Preferably, when the bluetooth broadcast packet is judged to contain neither the packet identifier nor the control identifier according to the parsed bluetooth broadcast packet, other identifier processing is performed on the bluetooth broadcast packet.

and step S609, other identification processing is carried out, if the grouping identification and the control identification are not contained, other identification processing is carried out, and S606 is carried out after the other identification processing is finished.
It can be seen that the invention can effectively prevent the controlled device from being interfered to cause error grouping by limiting the controlled device to be executed in a certain time when being powered on, and simultaneously, the invention changes the key identification from short pressing identification to long pressing identification after the group key is pressed to the time threshold value of group setting, continuously sends the Bluetooth broadcast packet containing the remote controller ID, the group identification and the group number in the mode of the Bluetooth broadcast packet under the condition of continuously pressing the group key to prevent error triggering of the short pressing group, and completes grouping by continuously sending the Bluetooth broadcast packet after the group key is triggered, the controlled device only needs to detect the Bluetooth broadcast packet containing the group identification a few times, thereby ensuring the reliability of group setting, after completing grouping, the remote controller sends control commands each time and contains the remote controller ID and the group number, so that the controlled device only responds to the stored remote controller ID and the group number, the purpose of realizing grouping control by a single remote controller is realized.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the scope of the invention should be determined from the following claims.
