Data transmission control method and related device

The invention provides a data transmission control method and a related device, and relates to the technical field of communication, and the specific implementation scheme is as follows: when to-be-transmitted data is detected, a communication module is controlled to enter an open state; sending a networking enabling command to the successfully started communication module, and controlling the serial interface to write to-be-transmitted data into the communication module when the communication module is in a networking execution state; and when the communication module is in the networking success state, controlling the communication module to upload the written data to a background server. Through the implementation of the scheme, after the communication module of the embedded equipment is started, serial port data transmission is started by using the networking time window of the communication module, and data uploading can be performed immediately after the communication module is successfully networked, s
