./uart_test/200b0
the pressure measurement parameters can be configured. Where 200 is 200 bytes per transmission and reception, and b0 is the data type of the data packet.
Step S300: based on the pressure measurement parameters, a serial port test program is executed to generate a first pressure measurement data packet.
In some embodiments, in combination with steps S100 to S200, based on the pressure measurement parameters input by the user, the intelligent module executes the serial port test program to generate a corresponding pressure measurement data packet (i.e., a first pressure measurement data packet).
Optionally, the pressure parameters include the pressure packet size and data type, i.e. 200 bytes and b0 as described above. The data types may include one or more of the following: numbers, English letters, punctuation marks. Specifically, b0 represents a pure number, b1 represents a pure english alphabet, b2 represents a pure punctuation mark, b3 represents a combination of a number and an english alphabet, b4 represents a combination of a number and a punctuation mark, b5 represents a combination of an english alphabet and a punctuation mark, and b6 represents a combination of a number, a punctuation mark, and an english alphabet.

If the first pressure measurement data packet and the second pressure measurement data packet are the same, namely the byte length is the same and each byte is the same, the value j of the counter is added by 1. If the first pressure measurement data packet is different from the second pressure measurement data packet, namely the length of the bytes is different or at least one byte is different, popping up and displaying the different places, exiting the serial port test program and ending the test.
In some embodiments, the pressure measurement parameters include, in addition to the pressure measurement packet size and data type, one or more of the following: serial port name, baud rate, and pressure measurement times. Wherein, serial port name can be the name or the only ID of serial port, can show which serial port of test when intelligent module has a plurality of serial ports. The baud rate represents the rate of data transfer. The number of pressure measurements indicates the number of times of repeatedly performing the steps S400 to S500 to transmit and receive the pressure measurement packet. When the pressure measurement parameters simultaneously include the size of the pressure measurement data packet, the data type, the serial port name, the baud rate and the pressure measurement times, the instructions input by the user when the pressure measurement parameters are configured on the console are as follows:
adb shell
su
cd system/bin
./uart_test/dev/ttyHS1 3000000 200b0 10000000

In some embodiments, when the pressure measurement parameter includes the number of pressure measurements, as shown in fig. 5, the serial port testing method further includes:
step S600: and judging whether the value of the counter is greater than or equal to the configured pressure measurement times. If the value of the counter is greater than or equal to the configured pressure measurement times, step S700 is executed, otherwise, step S400 is returned to.
Step S700: and exiting the serial port test program.
Optionally, the intelligent module determines whether the value j of the counter is greater than or equal to the configured number of pressure measurements. And if the value j of the counter is greater than or equal to the configured pressure measurement times, indicating that the pressure measurement is finished, quitting the serial port test program, and finishing the test. And if the value j of the counter is less than the configured pressure measurement times, returning to the step S400, repeatedly executing the sending and receiving of the pressure measurement data packet, exiting the serial port test program until the value j of the counter is equal to the pressure measurement times, and ending the test.
