2.3. AT+QFDEL Delete the File in the Storage
AT+QFDEL deletes a single file or all the files in the specified storage.

2.4. AT+QFUPL Upload File to the Storage
1. AT+QFUPL uploads the file to storage directly. If there is a file in the storage which has the same
name with the file to be uploaded, it will report the error.
2. There are three ways to exit from the transparent transmission mode:
The data uploaded reaches the <file_size>.
The time without any data inputted reaches <timeout>.
When the data is transmitted, the DTR PIN (AT&D1 should be set.) is pulled high or the valid
“+++” is inputted.
3.
To prevent the “+++” from being misinterpreted as data, it should comply to the following sequence:
Do not input any character within T
1 time (1 second) before inputting “+++”.
Input “+++” during 1s, and no other characters can be inputted during the time.
Do not input any character within T1 time (1 second) after “+++” has been inputted.
The current result “+QFUPL: <upload_size>,<checksum>” is outputted, and the module exits
from the transparent access mode, return OK.
