Detailed ways

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

As shown in FIG. 1, a self-generating remote control method includes the following steps:

As a preferred implementation, the step B specifically includes:

The remote controller adds the command information to be transmitted in the Bluetooth broadcast data packet and sends it to the receiving end; the receiving end filters the UUID or Bluetooth address of the Bluetooth device other than the remote controller, and broadcasts the command information in the packet after receiving the broadcast data sent by the remote controller. Extract it and parse it into a command that the receiver can recognize.

Bluetooth can not directly interact with the host when transmitting broadcasts. This can reduce the power consumption due to interactions in many cases. Since these broadcast data itself can carry a small amount of data. For example, minor or major data in a Bluetooth broadcast packet. Our button information (remote command) is placed in the minor and major areas, and then the corresponding modification is made at the receiving end of the broadcast, the button information of the modulation in the broadcast packet is extracted, and then converted into the key value recognized by the system, such as UP, DOWN. Wait for the button to complete the button operation of the remote control.

As shown in Figure 2, it shows Data format of major, minor data, a BYTE remote control software hardware version, a BYTE device ID, two BYTE remote control key values, three private data, smart box or Bluetooth host device after receiving this broadcast, separated This three private data. I got the button information sent by the remote control. Thereby controlling the corresponding action of the UI.

Further as a preferred embodiment, the remote controller encrypts the broadcast data, and the receiving end decrypts the broadcast after receiving the broadcast. As shown in FIG. 3, for example, data can be encrypted from the sixth byte.

The following describes the implementation of data communication step B by taking a Bluetooth low energy sensor as an example. In this embodiment, the sensor acts as a signal transmitting end, and periodically collects the collected data. After receiving the data, the mobile phone records the data as a data receiving end, and displays the data.

When the mobile phone receives the connectable broadcast data sent by the sensor, it starts to record data. When there is downlink data to be sent to the sensor, after the mobile phone receives the connectable broadcast, the downlink data is placed in the downlink connection package, and the data is initiated. Connection, after the sensor receives this particular connectable packet, parses the data and completes the specified configuration action. Since there is very little data and no absolute real-time operation is required, the data is placed on the broadcast and interacted at regular intervals. Since the interconnection between the sensor and the handset is as small as possible, there is no need to consider the power consumption and compatibility issues caused by connections, pairing, and the like. It achieves very low power consumption and runs Bluetooth, even in standby mode. When the external power is available, the device is woken up and data is transmitted. To avoid battery, you can work only by collecting environmental energy.

Sensor transmitter:

After the Bluetooth is powered on, it enters the sleep mode, and the timer wakes up the system periodically. After the system wakes up, collect the temperature and humidity data of the environment, generate broadcast data packets, configure broadcast parameters, and set the broadcast to be unconnectable (of course, you can also transmit connectable broadcasts, but the time interval of the broadcast is different, and the specific consumed power is different. Configured according to the actual application), the time interval is set to 100ms. After the data is repeatedly sent 2-5 times, the system enters the full sleep mode, waiting for the next external wake-up or timer wake-up. Guaranteed 0 power consumption during sleep, or mode with lowest power consumption.

Host receiving:

After the host is opened, the host configures the broadcast UUID filtering and waits to receive the broadcast. After the host receives the broadcast, it parses the data and records and saves the received sensor data. When there is a sensor to be sent, the host initiates a connection request for the connection data to the sensor, and transmits the data to the sensor. After the sensor receives the data, it does not respond and immediately closes the connection. Switch the broadcast to a new state. Avoid unnecessary connection power consumption. Complete the down command. Under normal circumstances, there is no data going down to the sensor, and this action is only performed when there is a command to write to the sensor.

When the broadcast channel interference is serious, in such an environment, the host side may be required to make some modifications to the remote control to specify some non-broadcast channels to avoid the problem of broadcast channel interference. This is basically a software configuration problem, as long as both parties press The agreed configuration is configured. You can avoid the problem of remote control interference. However, due to changes in the broadcast channel, the accuracy of the connection when paired with other normal Bluetooth devices is slightly reduced.

As a preferred implementation, the step B further includes:

When the user presses the remote control button a single time, the remote controller transmits a broadcast on a single channel. When the user continuously presses the remote control button, the remote controller simultaneously transmits a connectable data broadcast on three broadcast channels, and the receiving end responds after the corresponding channel answers. The remote controller records the channel of this response and uses it as a single channel for the next communication.

Since Bluetooth is a fixed three broadcast channels transmitting at the same time, it is more susceptible to interference, and the energy of each acquisition is very limited. So at the time of launch, we will do some optimization of the sexual energy. For example, in these three broadcast channels to do frequency hopping optimization, this will transmit more times under the same energy conditions, improving the reliability of data reception. The possibility of losing data in the air is reduced.

Usually, the broadcast of Bluetooth is transmitted simultaneously on three channels, that is, each time a data packet is sent, three channels transmit the same data packet, and in fact, the receiving end only needs to receive data on one channel. Therefore, one channel sends three times and three channels need to send the same amount of power, but in fact the receiver only receives one channel of the broadcast, so we can jump on the 3 channels of the Bluetooth broadcast without the frequency hopping. Frequency, to achieve the purpose of reducing the power consumption of the transmission.

Specifically, usually broadcast broadcast is not connectable broadcast, single button, that is, single channel, 1-n broadcast (the launch time is determined according to the actual collected power, generally 2-5 times) After that, it indicates that the receiving end may not receive the button information. The system switches to the frequency hopping switching broadcast, that is, transmits the connectable broadcast. At this time, the remote controller monitors the responses of the three broadcast channels, and monitors one of the broadcast channels as the next broadcast. The frequency hopping switching mode is triggered until the user repeatedly presses a button.

Implementation principle: The power source of the Bluetooth broadcast is the pressure when the button is pressed, when the user presses the remote control to take a light control button. If the light is not lit, it will be repeated several times. If the currently broadcasted channel is undisturbed, the light will be illuminated when the button is pressed, and the person will not press the button again, and the communication for transmitting and receiving will be no problem. If no data is received, the light will not illuminate, indicating that the channel is disturbed and the communication channel needs to be switched. When the same button operation is repeated 2-3 times or more, the collected power is also much more than that of a single button. At this time, the transmission can be connected to the broadcast, that is, the data broadcast can be connected in three broadcasts at the same time, and the receiving end corresponds. After the channel response, the transmitting end records the channel of the response, and uses it as a single channel for the next communication, thereby reducing the power consumption of about 2/3 and improving the user's button sensitivity.

Energy optimization is mainly to adjust the transmit power and power consumption when the system starts. Adjust the transmit power, which is adjusted according to the actual usage. For example, the transmit power that we initially defined according to the usage scenario is 0dBm. If the key loss rate of the button is less than 0.1% during use, it can be considered that the transmit power can be reduced to reduce Power consumption. There are many aspects to the energy required to start the system. There are several optimizations as follows.

Use a high-quality ultra-low-power reset chip to avoid power consumption caused by long reset time when the chip is powered on.

Using a high-quality crystal oscillator, the chip can be quickly started and stabilized, reducing the consumption of startup energy.

Reduce the amount of code and reduce the load time of the code.

Optimize the peak current during the startup process to avoid the sharp change of the power supply voltage caused by the peak large current, and increase the AC loss, electromagnetic radiation loss, reset and other issues of the circuit.
