In this embodiment, a bluetooth module testing method is provided, which may be used in the upper computer in the bluetooth module testing device, and fig. 3 is a flowchart of the bluetooth module testing method according to an embodiment of the invention, as shown in fig. 3, where the flowchart includes the following steps:
step S301, a test program downloading instruction is sent to the test control module through the interface conversion module, so that the test control module supplies power to a plurality of Bluetooth modules to be tested on the Bluetooth module tray based on the test program downloading instruction, and the test program in the test program downloading instruction is downloaded to the plurality of Bluetooth modules to be tested on the Bluetooth module tray.

Wherein the test program is determined by a tester. In order to test the bluetooth module to be tested, the test program needs to be downloaded to the bluetooth module to be tested first, and in this embodiment, the test data of the bluetooth module to be tested is received through the standard bluetooth module, so the test program needs to be downloaded to the standard bluetooth module in advance.
Step S302, under the condition that the plurality of Bluetooth modules to be tested complete the downloading of the test program, sending a power supply stopping instruction to the test control module so that the test control module stops supplying power to the plurality of Bluetooth modules to be tested on the Bluetooth module tray based on the power supply stopping instruction.
Under the condition that all the Bluetooth modules to be tested finish downloading the test program, the upper computer test control module sends a power supply stopping instruction, and the fact that power-off processing is needed to be carried out on a plurality of Bluetooth modules to be tested before the test control module sends the test instruction is needed to be explained.
Step S303, after sending a power supply stopping instruction to the test control module for a preset period of time, sending a test instruction to the test control module.
The test instruction is used for controlling the test program in the plurality of Bluetooth modules to be tested to run so as to test the plurality of Bluetooth modules to be tested. Of course, the test command also controls the test program in the standard bluetooth module to run to receive the test data of the bluetooth module to be tested.
Specifically, as shown in fig. 4, the standard bluetooth module and the bluetooth modules to be tested receive the test instruction, and the test programs in the standard bluetooth module and the bluetooth modules to be tested start to operate, and the specific operation process is as follows:
the standard Bluetooth module scans Bluetooth broadcasting signals, filters broadcasting signals of the Bluetooth module which is not to be tested in a keyword filtering mode, and receives the broadcasting signals of the Bluetooth module which is to be tested;
acquiring an MAC address according to the received broadcast signal of the Bluetooth module to be tested, and establishing connection with the Bluetooth module to be tested based on the MAC address;
after the Bluetooth module to be tested is connected with the standard Bluetooth module, test data are sent to the standard Bluetooth module, wherein the test data comprise the version number of the Bluetooth module to be tested, GPIO high-low level, working voltage and current, signal intensity and frequency offset.
After the frequency offset is required to be connected with the standard Bluetooth module, the clock offset of the Bluetooth module to be tested and the standard Bluetooth module is measured through a Bluetooth channel. The Bluetooth clock is taken from a free-running local clock, and the local clock is never adjusted and turned off, is a reference of other clocks, and is generated by a crystal oscillator. The timing in the bluetooth channel and the frequency hopping of the channel are determined by the clock of the master node (i.e., standard bluetooth module).
When the Bluetooth module to be tested is connected with the standard Bluetooth module, the clock of the standard Bluetooth module is transmitted to the slave node (the Bluetooth module to be tested), and the Bluetooth module to be tested adds an offset on the local clock of the slave node to realize the synchronization with the standard Bluetooth module.

The frequency deviation of the Bluetooth module to be tested can be obtained by combining the two clock offsets, namely the frequency deviation delta f of the Bluetooth module to be tested is obtained by combining the two clock offsets, wherein delta f=f 2 -f 1 。
In order to ensure the accuracy of the test data broadcast to the standard bluetooth module, the bluetooth module to be tested continuously transmits the test data to the standard bluetooth module a plurality of times, and illustratively, continuously transmits the test data 5 times.
And the standard Bluetooth module reports the test data sent by the Bluetooth module to be tested for multiple times to the upper computer through the TTL serial port.
It can be understood that the standard bluetooth module establishes connection with any bluetooth module to be tested, and after receiving the test data of the bluetooth module to be tested, the standard bluetooth module disconnects from the bluetooth module to be tested, continues to scan broadcast signals of the remaining bluetooth modules to be tested, and receives the test data of the remaining bluetooth modules to be tested until all the test data of all the bluetooth modules to be tested are received.
Step S304, receiving test data of the tested Bluetooth modules to determine test results of the tested Bluetooth modules.
And the standard Bluetooth module sends the test data of the tested Bluetooth modules to the upper computer, and the upper computer receives the test data of the tested Bluetooth modules to determine the test results of the tested Bluetooth modules.
According to the Bluetooth module testing method, the upper computer receives the testing data of the plurality of Bluetooth modules to be tested through testing control of the plurality of Bluetooth modules to be tested, and determines the testing results of the plurality of Bluetooth modules to be tested, so that the plurality of Bluetooth modules to be tested can be tested at one time, and the testing efficiency of the Bluetooth modules to be tested is improved.
In this embodiment, a bluetooth module testing method is provided, which may be used in the upper computer in the bluetooth module testing device, and fig. 5 is a flowchart of the bluetooth module testing method according to an embodiment of the invention, as shown in fig. 5, where the flowchart includes the following steps:
step S501, a test program downloading instruction is sent to the test control module through the interface conversion module, so that the test control module supplies power to a plurality of Bluetooth modules to be tested on the Bluetooth module tray based on the test program downloading instruction, and the test program in the test program downloading instruction is downloaded to the plurality of Bluetooth modules to be tested on the Bluetooth module tray.
Please refer to step S301 in the embodiment shown in fig. 3 in detail, which is not described herein.
Step S502, the downloading progress of the test program in each Bluetooth module to be tested is monitored in real time.
As shown in fig. 6, the upper computer monitors the downloading progress of the test program in each bluetooth module to be tested in real time.
Step S503, if it is detected that there is a Bluetooth module to be tested with failed download, restarting the download flow of the test program to the Bluetooth module to be tested.
As shown in fig. 6, the upper computer monitors the downloading progress of the test program of the bluetooth module to be tested in real time, and restarts the downloading flow of the test program when the bluetooth module to be tested with the downloading failure is monitored, and downloads the test program to the bluetooth module to be tested with the downloading failure again.
