Embodiment

[0027] Such as figure 1 Shown, a kind of test method of bluetooth low energy consumption transmission rate, comprises the following steps:

[0028] S01: During the test, fill up the buffer of the controller. When sending data, judge the size of the remaining buffer. If the buffer is not full, send continuously, and wait if it is full;

[0029] S02: Grab the air packets of the data channel of Bluetooth low energy consumption, analyze the number of data packet interactions in a data channel, and determine the number of data packets sent in a connection event packet_num;

[0030] S03: The transmission rate of Bluetooth Low Energy is Rate, which is calculated by the following formula:

[0031] Rate=(packet_size*packet_num) / con_interval

[0032] Among them, packet_size is the size of each data packet, and con_interval is the connection interval.

[0033] Bluetooth low-power data communication occurs in connection events. In each connection event, the master and slave can exchang...

Abstract

The invention discloses a low-power-consumption Bluetooth transmission rate testing method, and the method comprises the following steps: filling a buffering region of a controller during testing, and judging the size of a remaining buffering region during the transmission of data: continuing to carry out the transmission if the buffering region is not full, or else carrying out no operation but waiting; grabbing an air packet of a data channel of low-power-consumption Bluetooth, analyzing the number of interaction times of data packets in one data channel, and determining the number of data packets transmitted in one connection event; setting the transmission rate of the low-power-consumption Bluetooth as Rate, and calculating Rate =(packet_size*packet_num) / con_interval, wherein packet_size is the size of each data packet, and the con_interval is the interval of connection events. The measured transmission rate is relatively accurate, and the method can be used for reference of the transmission rate demands of an actual chip when the low-power-consumption Bluetooth technology is used for achieving the big-data transmission application.

Description

technical field [0001] The invention relates to a method for testing the transmission rate of bluetooth, in particular to a method for testing the transmission rate of bluetooth with low power consumption. Background technique [0002] With the rapid development of information technology, low-cost, highly integrated, low-power wireless sensor network (WSN) has been widely used in military, medical, transportation, environmental monitoring, smart home and other fields. Considered to be one of the most important technologies of the 21st century. Wireless sensor networks are generally established only to measure simple physical environment data such as temperature, humidity, and blood pressure. However, researchers have not satisfied the monitoring needs of wireless sensor networks for simple information, and have introduced large-scale multimedia information into wireless sensors. Sensing networks to monitor activity. [0003] The Bluetooth SIG released version 4.0 of the Bl...
