Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a communication method, an apparatus, and a message queue telemetry transport protocol client.
Background
The message queue telemetry transport protocol (MQTT) is widely applied to an embedded system of the Internet of things as an instant messaging protocol with low cost and low bandwidth occupation. With the continuous development of communication technology, more and more manufacturers support the MQTT protocol in the communication module, and provide an Attention (AT) instruction set to control the communication module to connect to the cloud platform and the server through the MQTT protocol. However, because the AT instruction sets of different types of communication modules have great differences, the portability of application software developed based on a specific AT instruction set is poor, and the update cost of products is high.
In the technical solutions of some existing embedded MQTT client implementation methods, an AT instruction set that controls a Transmission Control Protocol/Internet Protocol (TCP/IP) function in a package communication module is generally used as a socket interface, and then an MQTT Protocol and a client are implemented on the basis of the socket interface. The disadvantages of these schemes are that users are required to implement MQTT protocol and clients on the basis of sockets, which increases burden for writing network applications for users. Moreover, the MQTT protocol and the implementation of the client occupy more resources, which makes these schemes difficult to be applied in resource-intensive embedded systems.
In summary, the message queue telemetry transport protocol client in the prior art needs to communicate data through a specific protocol stack interface, but cannot directly communicate with the communication module having the MQTT protocol through the MQTT client, which results in poor portability of the communication module having the MQTT protocol in the prior art.

wherein, the response data is the response data after the target communication module executes at least one target adaptation function; the active reported data is response data of the target communication module number which does not execute the target adaptation function.
6. The method according to claim 5, wherein in a case that the target adaptation function is a parsing instruction function, controlling the prompt instruction module to communicate with the target communication module according to the target adaptation function further comprises:
and controlling the prompt instruction module to analyze the received response data and/or the actively reported data according to the analysis instruction function.
7. The method of claim 1, wherein the plurality of communication modules are configured in a same adaptation layer.
8. The method of claim 1, further comprising:
sending a first message to an MQTT server through the target communication module, wherein the first message comprises a topic subscription message and/or a topic publishing message;
and receiving a prompt instruction fed back by the MQTT server through the target communication module.
9. The utility model provides a communication device, is applied to message queue telemetry transport protocol MQTT customer end, MQTT customer end is including suggestion instruction module and a plurality of communication module, its characterized in that includes:
the acquisition module is used for acquiring first parameter information, and the first parameter information is used for determining a target communication module which is communicated with the prompt instruction module;
and the control module is used for controlling the prompt instruction module to communicate with the target communication module.
10. A message queue telemetry transport protocol, MQTT, client, comprising: processor, memory and program stored on the memory and executable on the processor, which when executed by the processor implements the steps of the communication method according to any of claims 1 to 8.
