the configuration format obtaining module is used for obtaining a corresponding configuration format according to the attribute type if the attribute type is found in the user-defined service attribute list;
and the processing module is used for substituting the attribute values into the configuration format to generate an operation instruction and executing corresponding operation according to the operation instruction.
6. The BLE bluetooth device of claim 5, wherein the custom service attribute table contains a preset number of standard attribute types and attribute handle values that correspond one-to-one to the standard attribute types;
the configuration format obtaining module comprises:
an attribute obtaining unit, configured to, if a standard attribute type that is the same as the attribute type is found in the customized service attribute table, obtain an attribute handle value corresponding to the same standard attribute type as a target attribute handle value;
and the configuration format acquiring unit is used for acquiring the configuration format corresponding to the target attribute handle value.
7. A BLE Bluetooth device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method of remotely controlling a BLE Bluetooth device according to any one of claims 1 to 4 when executing the computer program.
