Problems solved by technology
[0003] Bluetooth remote controllers are widely used due to their advantages such as long transmission distance, low power consumption, barrier-free, and support for more complex protocols. However, the traditional Bluetooth protocol is complex and requires a higher chip specification to support it. The use process is also relatively complicated, but the remote control method based on the Bluetooth broadcast packet is simple to operate, low in cost, can be paired quickly, and can also be used for one-to-many control in special application scenarios such as production lines, which will definitely be respected

Embodiment Construction
[0025] The remote control method based on the Bluetooth broadcast packet includes the following steps: including a code matching method, a data transmission method and a data processing method in sequence, the remote controller after the code matching connection can transmit data to the host end, and the host end performs data processing after receiving the data A series of data processing.
[0026] Step 1, use the remote controller for the first time, and use the code pairing method based on the Bluetooth broadcast packet to pair the remote controller and the Bluetooth host; the specific process of the code pairing method is:
[0027] 1.1 The remote control randomly generates a device ID, and broadcasts continuously for a period of time in the form of Bluetooth broadcast packets, and the broadcast packet data is packaged and sent according to the packet format of Bluetooth ADV_NON_CONN_IND;
[0028] 1.2 After receiving the Bluetooth broadcast packet data reported by the recei...

The invention relates to a remote control method based on a bluetooth broadcast packet, which comprises the following steps: 1)using a remote controller at first time, employing a code matching method based on the bluetooth broadcast packet to match the remote controller with a bluetooth host terminal; 2) transmitting data to the host terminal by the remote controller, packaging data according to a format of bluetooth ADV_NON_CONN_IND packet, wherein each packet is transmitted for several times repeatedly for avoiding data packet dropout; and 3) processing data, and respectively performing corresponded treatment on different types of data to control the host terminal. According to the invention, the method has the advantages of simple operation, low cost and rapid matching, and can realize one-to-many control under special application scenes such as production line.
Description
technical field [0001] The invention relates to a remote control method realized based on bluetooth broadcast packets. Background technique [0002] Bluetooth (Bluetooth) is a new type, open, low-cost, short-distance wireless connection technology, which can replace short-distance cables and realize wireless transmission of voice and data. This effective and cheap wireless connection technology can easily connect computers and portable devices, PDAs, mobile phones, camera phones, printers, digital cameras, headsets, keyboards and even computer mice to achieve wireless transmission of multimedia information. Within its reachable range, various information-based mobile portable devices can realize seamless resource sharing. Bluetooth supports point-to-point and point-to-multipoint communication. In order to realize point-to-multipoint communication, data is sent in the form of broadcast, so that receivers within a certain range can receive the data. [0003] Bluetooth remote...
