The bluetooth signal generally refers to a signal that a target device requests a bluetooth connection. The electronic device generally refers to an electronic device having a bluetooth connection function and a light sensor, such as an electronic book reader, a smart phone, and the like.
Step 202, determining whether the intensity value of the bluetooth signal reaches a preset threshold value.
In some embodiments, based on the detection result of step 201, the executing entity (electronic device) may determine whether the intensity value of the bluetooth signal reaches a preset threshold. Here, the strength value of the bluetooth signal is generally a value representing the strength of the bluetooth signal. The reaching of the preset threshold may be equal to or greater than the preset threshold. The preset threshold value is generally a preset value.
in some optional implementations of some embodiments, the executing entity may obtain a predetermined number of intensity values of the bluetooth signal, resulting in the first set of intensity values. And deleting the maximum intensity value and the minimum intensity value in the first intensity value set to obtain a second intensity value set. A median of the second set of intensity values is determined. For each intensity value in the second set of intensity values, determining a difference between the intensity value and the median, and in response to determining that an absolute value of the difference is less than or equal to a predetermined value, determining the intensity value as valid data. And determining the average value of the number of the effective data as the signal strength value of the Bluetooth signal in response to the determined number of the effective data reaching the preset number.
Here, the predetermined number of the intensity values of the bluetooth signal is generally set to be greater than or equal to 3. The predetermined number may be a number set by a person, for example, 3, 5, etc. The Median (media) is also called Median, and usually refers to a proper term in statistics, and is a number in a middle position in a set of data arranged in sequence. For a finite number set, the median can be found by ranking all observations high and low. If there are an even number of observations, the median is usually taken as the average of the two most intermediate values. For example, the number set includes three numbers of 1, 3 and 5, and the median of the number set is 3. The above-mentioned number of valid data reaching the predetermined number generally means that the number of valid data is greater than or equal to the predetermined number. The predetermined number may be a number set by a human. The above signal intensity value generally refers to a value for characterizing the signal intensity.

as an example, when the content of the data to be transmitted is too large to reach a preset threshold, the size of the data packet is fixed, and the data to be transmitted cannot be encapsulated into one data packet, so that the data to be transmitted is encapsulated into a plurality of data packets, each data packet transmits data of a specific size, and the data packets are transmitted in batches until the data to be transmitted is completed. The preset threshold is usually set according to the maximum data capacity of the data packet, for example, the preset threshold may be that the size of the data a to be transmitted is greater than 100M.
In some optional implementations of some embodiments, the electronic device may obtain data information of the data to be transmitted. The data information includes the data length of the data to be transmitted and the check code of the data to be transmitted.

The check code is generally referred to as an error detection code, and may be, for example, a binary number indicating whether the number of 1's in a given number of bits is an odd number or an even number. The check code may be calculated by using a calculation method such as a code distance, parity check, hamming check, cyclic redundancy check, or the like.
Here, the electronic device may obtain data information of data to be transmitted, perform data encapsulation on the data to generate a data packet, and send the data packet and the data information of the data to be transmitted to the target device.
