And the universality is stronger, the method is irrelevant to hardware driving, the method is not limited by hardware equipment, and any communication module provided with a serial communication interface can be used for carrying out adjustment and measurement by using the method provided by the embodiment of the invention.
In order to facilitate understanding of the above embodiments of the present invention, an implementation procedure of a method for tuning a communication module with a serial communication interface is described below in connection with an interaction procedure between a tuning device and a target communication device.
The target communication device runs a call setup proxy service program and the call setup device runs a call setup proxy client program. Since the tone test device is connected to the target communication device through the ethernet interface, the tone test proxy service program and the tone test proxy client program can also be connected and communicate through the ethernet interface.
The call and test agent service program is used for carrying out serial port communication with the target communication module on one hand and carrying out TCP network communication with the call and test agent client program on the other hand. The call out agent client program is used for carrying out serial port communication with the target call out program on the call out device on one hand, and is used for carrying out TCP network communication with the call out agent service program on the other hand.
When starting the adjustment, firstly running an adjustment and measurement proxy service program, wherein the program runs as a background program and exists all the time in the whole adjustment and measurement process; then running the debugging agent client program, the debugging agent client program generates a virtual serial port on the debugging device and communicates with the target debugging program running on the host. The target debugging program is directly communicated with the serial port, a virtual serial port generated by the debugging agent client program is opened from the target debugging program, the baud rate and the like are set, and after the setting is finished, the target debugging program provided by a manufacturer can be used for debugging, so that the effect is equivalent to the effect that the target debugging program is directly connected with the target communication module through the serial port for debugging.
For the target communication device, the call agent running thereon runs in the background as a relay program. The target communication module has a UART interface (for example, a serial communication interface is a UART interface) on hardware, and is connected with a UART interface of the target communication device, so that the debugging agent service program can communicate with the target communication module through the UART interface of the target communication device.
When the debugging proxy service program is started, the UART interface of the target communication module is opened, and default parameters such as baud rate, stop bit and the like are set, so that the debugging proxy service program can communicate with the module. And, the call agent opens a TCP Server (TCP Server) and waits for a TCP connection request from the call agent client. When a TCP connection request initiated by the call agent client is received, the TCP connection to be established is successful, and the work can be formally started.
When the debugging proxy service program runs, after feedback data is sent from the UART interface of the target communication module, the feedback data is not processed, and the feedback data is directly sent to the debugging equipment through the TCP connection established in the last step and is processed by the debugging equipment. After the call proxy service program receives call data from the TCP connection with the call device, the call data is forwarded to the serial port of the target communication module as it is.
After the call testing agent client program is started, a virtual serial port is generated in an operating system of the call testing equipment. When the target debugging program tries to open the virtual serial port, the debugging agent Client acts as a TCP Client (TCP Client) and initiates a connection with a remote TCP server configured in advance. When the TCP connection is established, the target debugging program also shows that the virtual serial port is successfully opened, and then the virtual serial port can normally communicate with the target communication module to be debugged.
The call agent client starts the data forwarding function after the TCP connection is established successfully.
