[0060] Example 1
[0061] Step 1: First use the bsdiff differential algorithm to obtain the required differential upgrade package on the server.
[0062] Step 2: The server issues an upgrade instruction to the terminal, and after the terminal receives the upgrade instruction, it reads the software version of the current module and records it;
[0063] Step 3: The terminal responds to the upgrade instruction issued by the server, and the server begins to issue the upgrade package; after the upgrade package is downloaded, the terminal replies to the server to confirm that the download is complete;
[0064] Step 4: The terminal sends an AT command to the module, starts the software upgrade and informs the module upgrade package size;
[0065] Step 5: The module responds to the AT command, and the terminal transmits the upgrade package to the module;
[0066]Step 6: After the module completes the upgrade package reception, use the optimized bsdiff algorithm to directly update the old ...
