The communication unit may be, for example, the communication unit 103 in fig. 1, and for a specific description of the communication unit, please refer to the related description in fig. 1, which is not repeated here.

The communication unit in the first module sends the data to be sent to the second module by Wi-Fi communication.

In a possible implementation, after the first module completes sending the data to be sent, the processing unit of the first module sends first indication information to the first electronic device, where the first indication information is used to instruct the first electronic device to delete the data to be sent in the first folder. In the scheme, after the first module finishes transmitting the data to be transmitted, the indication information is transmitted to the first electronic device, the data to be transmitted stored in the first folder is deleted, the storage space of the first electronic device can be saved, and meanwhile, a user can be prompted that the data to be transmitted is already transmitted.

It should be noted that, the user stores the data to be sent into the first folder, and the first module automatically performs the processes of data monitoring, data processing, data sending, data deleting, and the like.

In one possible implementation, after the user stores the data to be sent in the first folder, the processing unit in the first module sends indication information to the first electronic device, where the indication information is used to enable the first electronic device to display the progress of data sending.

S406, the second module stores the received data to be sent into a second folder.

In a possible implementation, the second module receives the data to be sent by the first module through the communication connection established in step S404.

In a possible implementation, the second module stores, through its processing unit, the received data to be sent in the second folder created in step S403B.

In another possible implementation, the second module may store the received data to be sent in the second folder created in step S403B, where the processing unit and the communication unit cooperate.

The steps of the data transmission method shown in fig. 4, which require user operations, include connecting the first module with the first electronic device, connecting the second module with the second electronic device, and storing the data to be transmitted in the first folder. Therefore, the data transmission method shown in fig. 4 is simple and convenient to operate, and the data transmission is not limited to the storage space of the external device.
