Description

Communication method, device and message queue telemetry transport protocol client

technical field

The present application relates to the technical field of communication, in particular to a communication method, device and message queue telemetry transmission protocol client.

Background technique

Message Queuing Telemetry Transport Protocol (MQTT), as a low-overhead, low-bandwidth instant messaging protocol, is widely used in embedded systems of the Internet of Things. With the continuous development of communication technology, more and more manufacturers support the MQTT protocol in the communication module, and provide Attention (AT) command set to control the communication module to connect to the cloud platform and server through the MQTT protocol. However, because the AT command sets of different types of communication modules are quite different, the portability of application software developed based on a specific AT command set is poor, and the cost of product replacement is high.

In some existing technical schemes for implementing methods for embedded MQTT clients, the AT command set that controls the Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol; TCP/IP) function in the communication module is usually used as a package. Socket interface, and then implement the MQTT protocol and client on the basis of the socket interface. The disadvantage of these solutions is that the user needs to implement the MQTT protocol and the client on the basis of the socket, which adds a burden to the writing of the user's network application. Moreover, the implementation of the MQTT protocol and the client needs to occupy more resources, making these solutions difficult to apply in resource-constrained embedded systems.

To sum up, the message queue telemetry transmission protocol client in the prior art needs to communicate through a specific protocol stack interface, but cannot directly communicate with the communication module with the MQTT protocol through the MQTT client, resulting in the prior art Communication modules with MQTT protocol have poor portability.

Specifically, initialize the MQTT client, call the MQTT client initialization interface, and set various parameters of the MQTT client. The MQTT client identifies the need to call the first target module initialization adaptation function through the first parameter; the second step: connect to the MQTT agent (Broker), and call the MQTT client connection interface; the third step: subscribe to the MQTT topic, and pass step 300 Call the MQTT client subscription interface, or publish the MQTT topic message, call the MQTT client publishing interface, and implement the topic subscription message and/or topic publishing message through the first message; through step 400, receive the feedback from the MQTT server A prompt instruction, performing a corresponding operation according to the feedback prompt instruction. That is to receive the subscribed topic MQTT message, the target communication module actively reports the MQTT message of the topic subscribed by the client according to the feedback prompt command, the MQTT client receives the MQTT message, and executes the corresponding callback function to notify the user that the subscribed message arrives and Execute the corresponding processing. Of course, if you want to disconnect, you can also send a second message to the MQTT server through the target communication module, and the second message includes disconnecting from the MQTT agent.
