The data file system information of the hardware device itself includes total storage capacity, usage amount, name, size, and modification time of each data file.

Step 409: judging the synchronization instruction, for reading the instruction, proceeds to step 410, otherwise proceeds to step 412;

Here, the synchronization instruction is composed of an instruction code and an additional code. Among them, the instruction code is divided into two types, including a read instruction and a write instruction; the instruction additional code includes the ID of the data file to be operated and the length of the data file.

Step 410: During the reading and sending of the data file, the yellow LED flashes for prompting the busy state, and after the read operation is completed, the process proceeds to step 411;

Here, the hardware device adds an ID according to the received instruction, obtains an ID that needs to read the data file, searches for the data file from the memory, and writes the data file content into the FIFO queue. (FIFO, First in First out), simultaneously starts the wireless transceiver and sends the contents of the FIFO to the terminal.

Step 411: Waiting for the terminal to return a response flag, if the response is successful, the hardware device lights the green LED for 5 seconds, otherwise the yellow LED is illuminated for 5 seconds; after the end, returns to step 408;

Step 412: The hardware device determines, according to the received instruction additional code, whether the data file to be written can be normally written. If the data file can be normally written, the writable response flag is sent, and the process proceeds to step 413, otherwise, the non-writable response flag is sent. And proceeds to step 414;

Step 413: Write operation, if the writing is completed, the hardware device returns a success response signal, and simultaneously lights up the green LED for 5 seconds, otherwise returns a failure response signal, and lights up the yellow LED for 5 seconds; after the end, returns to step 408;

Here, the hardware device receives the data file content to the FIFO through the wireless transceiver, and performs a Cyclic Redundancy Check (CRC) check, and writes the data file content to the data file system after the verification is passed.

Step 414: Unable to write, the hardware device lights up the yellow LED for 5 seconds; after the end, returns to step 408.

When the above hardware device is used to implement data storage and synchronization, if an unexpected interruption occurs, for example, a wireless connection is suddenly disconnected during transmission, the above implementation process enters an interrupt process, and the interrupt processing clears the site and returns to step 404 to wait. reconnect.

Step 513, delete operation, send delete instruction code to the hardware device, waiting for the returnable deleteable response flag; if it can be deleted, proceed to step 514; otherwise, the user is prompted not to delete, and returns to step 505;

Step 514: First prompt the user whether to delete, after the user confirms, send a special write command code to the hardware device, after the completion of the process proceeds to step 515;

Here, the delete operation can be regarded as a special write operation, and the instruction code has a data file ID, but the file length is 0.

Step 515, after the writing operation is completed, the device waits for the hardware device to return a response flag, and prompts the user to complete the operation according to the response flag; after the end, returns to step 505.

Step 603, if a read operation is required, proceed to step 604, a write operation is required, proceeding to step 605, otherwise proceeding to step 606;

Here, according to the data file system information returned by the hardware device, the local mirror data file information is compared, and according to the modification time of the data file, it is determined whether the write and read operations are currently required.

Step 604, the read operation, sending the read instruction code to the hardware device, and starting the receiving thread to receive the data file sent by the hardware device, after receiving the success and passing the CRC check, returning the success response flag, and saving the data file to the local Mirror, otherwise return a failure response flag; after the end, return to step 603;

Step 605, the write operation, send the write command code to the hardware device, waiting for the returnable writable response flag; if writable, the start sending thread reads the specified data file, and sends, and then returns to step 603;
