The protocol interface that must all support.
Embodiment two
Based on the system framework figure in embodiment one, the present embodiment proposes a kind of bluetooth TX (transmit) throughput performance
Test method, program used to perform the method are divided into the end Client and the end Server to run, and the end Client is as data
The role for sending and controlling, role of the end Server as data receiver and processing.Assess bluetooth equipment TX throughput performance to be measured
When, the end Client program operates in control unit 2, and the end Server program operates in control unit 1.Wherein, institute is being executed
Before stating test method, the end Client program and the end Server program are all copied in control unit 1 and control unit 2, transported
Row automatically selects suitable role in control unit 1 and control unit 2 according to test case demand in the test script of host
Program (Client program or Server program) is executed, and process flow diagram flow chart is as shown in Fig. 2, detail flowchart such as Fig. 3
Shown, the test method includes the following steps：
Step 1：Start the end Server program, reads the Bluetooth MAC address of Bluetooth adapter.
Specifically, the end the Server program operated in control unit 1 is than the end the Client journey that operates in control unit 2
Sequence first carries out.
Specifically, it after the end the Server program in control unit 1 starts execution, first reads out and is connected in control unit 1
Bluetooth adapter local mac address, the test script being then transferred to by ADB on host.
Specifically, before starting the end Server program, it may also include following setting operations：Test script on host is read
Test case is taken, testing data Packet type, and setting statistics number are parsed.
Step 2：Start the end Client program, obtains the Bluetooth MAC address of the Bluetooth adapter.
Specifically, by the test script on host by the bluetooth of the Bluetooth adapter obtained in the step 1
MAC Address sends control unit 2 to.
Step 3：Bluetooth equipment to be measured establishes connection according to the Bluetooth MAC address with the Bluetooth adapter.
Specifically, after the starting of the end Client program, the Bluetooth MAC address transmitted according to host is referred to by HCI
Order directly establishes bluetooth connection with the Bluetooth adapter.Bluetooth equipment scanning to be measured can be saved by this connection type to look into
It askes the time of the Bluetooth adapter, the time of bluetooth equipment is established in Bluetooth connection process around practical bluetooth scan for inquiries
Most time-consuming process, because of the influence of on-air radio interference etc., it is sometimes desirable to which scan for inquiries could repeatedly succeed, and greatly reduce
Production test efficiency.The end Server program in this method obtains Bluetooth adapter by HCI_Read_BD_ADDR HCI instruction
MAC Address, give bluetooth equipment to be measured by host transfer transmission, bluetooth equipment to be measured is straight according to Bluetooth adapter MAC Address
It connects and establishes connection with Bluetooth adapter.
Step 4：The bluetooth equipment to be measured sends the data packet for test to the Bluetooth adapter.
Specifically, the bluetooth equipment to be measured and the Bluetooth adapter are established after wireless connection, pass through the control
Unit 1 and described control unit 2 are arranged between the bluetooth equipment to be measured and the connecting link of the Bluetooth adapter
Packet mask attribute, the packet mask accurately can use certain type of data packet by bluetooth physical link.Right
When bluetooth is tested, the type of data packet that the effect length Bluetooth link physical layer transmission of data packet uses, and different type
Data packet noiseproof feature it is again different, therefore when implementing specific test operation, the data packet class to test as needed
Type generates the data packet of corresponding length range, the data packet of the corresponding length range by the software program in control unit 2 with
Machine generates, and ensures that the data packet length of transmission test every time is all inconsistent in this way, but all can be controlled in corresponding data packet
Within the length of type transfers.The following table shows the corresponding relationships for the type of data packet that data packet length and physical layer use.
It is worth noting that, packet mask attribute determines that physical link carries out data transmission used Packet type, by
It in the coding mode of bluetooth difference Packet type, anti-interference, data volume can be carried all is different, so packet mask is straight
Connecing influences transmitted data amount total size, and under default situations, it is that dynamic becomes that physical link, which carries out data transmission used Packet type,
Change, by the data length and air environment interference decision carried, this is impacted to different Packet type transmission performances are assessed, and
The present invention passes through the Packet type that packet mask property control is transmitted, preferential selection and the long immediate number of data to be transmitted packet
Carry out data transmission according to packet, so that the test of bluetooth throughput is more accurate.
Specifically, the setting of packet mask parameter instructs Change ConnectionPacket by standard HCI
Type Command is realized.
Packet mask mechanism is illustrated to the influence of bluetooth throughput, in bluetooth performance with specific example below
In test, a length of 350Bytes is wrapped in setting, if the data packet of 2-DH3 type is supported in packet mask setting, then due to 2-
DH3 packet load section (339,367) just meets 350Byte load, and therefore, test equipment can be selected preferentially closest to setting packet
Long 2-DH3 data packet transmits data；If the data packet for not supporting 2-DH3 type, test equipment is arranged in packet mask
Other kinds of data packet can be selected according to packet mask limitation, transmitting data can generate fragment in this way or other expenses are made
Throughput is caused to reduce at efficiency of transmission reduction.
Specifically, an important factor for influencing packet loss performance is external wireless interference and data packet length, for mould as far as possible
Intend true usage scenario, arranges WIFI router in test platform environment to increase air interference.
Specifically, the bluetooth equipment to be measured and the Bluetooth adapter are established after wireless connection, pass through the control
The auto- between the bluetooth equipment to be measured and the connecting link of the Bluetooth adapter is arranged in unit 1 and described control unit 2
Flush mechanism.The auto-flush mechanism is a kind of mechanism of software and hardware combining, is generally all propped up on present bluetooth equipment hardware
Standard auto-flush interface is held, the auto-flush mechanism can be avoided effectively because data packetloss causes data packet in base band
Unlimited re-transmission, and then influence bluetooth applications data blockings the problem of can not in time sending data, use auto-
Flush mechanism needs to cooperate suitable data packet time-out time, if data packet is not successfully transmitted away at the appointed time,
Hardware then removes currently transmitted data packet automatically and sends next data packet to be sent, passes through suitable software side in this way
Method can judge packet loss in receiving end, and this packet loss performance is for that need to guarantee the real-time of data transmission, and to the complete of data
The scene that whole property compensates by other means is extremely important, such as Bluetooth audio frequency application.Preferably, by link auto-flush's
Time is set as 1 second, specific Software Implementation be starting one 1 second timer thread, by call back function calculate 1 second at
The byte number of function transmission data.
Specifically, auto-flush mechanism specifies Devices to test packet to transmit time-out time, due to auto-flush mechanism
In the presence of, it will not block in poor transmission environment application layer, corresponding transmitted data amount can improve, and throughput is opposite to be improved, but
There are certain packet loss.
Specifically, the end Client program controls the bluetooth equipment to be measured with theoretical maximum throughput rate and fits to the bluetooth
Orchestration sends test data, and the theoretical maximum throughput rate is specified by test script according to test case, in practical survey
During examination, due to hardware scheduling performance, the influence of air interference packet loss, true Devices to test TX throughput rate is unable to reach
Theoretical TX throughput rate, so the throughput rate being successfully received when calculating Devices to test TX throughput rate with the end Server
Subject to.
Specifically, the end Server program and the end Client program use dual-thread implementation method, are with the end clilent program
Example, one of thread are responsible for sending blue-teeth data to be measured, another thread is responsible for calculating the throughput rate that data are sent, and pass through
The implementation method of dual-thread improves the accuracy of the reliability of program and packet loss performance test of handling up.
Step 5：After test, TX throughput test result is exported.
Specifically, the TX throughput rate for calculating bluetooth equipment to be measured is with 1 second for measurement period, updates this time within every 1 second
Instantaneous throughput rate in section can calculate Devices to test in the testing time using statistical method according to these instantaneous throughput rates
Handle up variance yields and average throughput rate.Handling up variance yields and average throughput rate will be as assessing bluetooth equipment performance to be measured
Important indicator, variance yields of handling up reflects the stability that bluetooth equipment to be measured is handled up, and numerical value is smaller to represent bluetooth equipment number to be measured
It is more stable according to transmitting；Average throughput rate reflects that bluetooth equipment to be measured is handled up maximum rate, and numerical value is bigger to represent bluetooth to be measured
The data volume that can be transmitted in the equipment unit time is bigger.
Specifically, the circular of throughput is：Throughput (kbps)=single performance test transmitted data amount is total
With/the unit time.
Specifically, test maximum throughput rate is being carried out simultaneously, for the integrality for guaranteeing data, the end Client is tested in every packet
CRC check information and the information tx_count that sends sequence number are added in data, the end Server judges to receive number according to CRC check information
According to integrality, only reception data CRC check information with transmission the CRC check information of data it is consistent when, just think data
It is successfully received, tx_count can understand in statistics reflects which bag data is lost.
Specifically, after test, output records the bluetooth equipment TX to be measured and handles up variance yields and average throughput
The test report of rate value.

The bluetooth equipment to be measured sends test data with theoretical maximum throughput rate, and the bluetooth equipment to be measured is with the end Server program
Operation, the RX throughput that the end Server calculates are the true RX throughput performance of bluetooth equipment to be measured.
After test, output records the bluetooth equipment RX to be measured and handles up variance yields and average throughput rate value
