if the first device does not support the external device, third network data with a data type of an instruction data type is sent to the external device, and the third network data is used for instructing the external device to analyze the third network data to obtain a function instruction corresponding to the third network data and executing the function instruction.
5. An apparatus expansion method according to claim 4, further comprising:
detecting a compatibility index between the first device and the external device;
if the compatibility index meets a preset index, determining that the first equipment supports the external equipment;
and if the compatibility index does not accord with the preset index, determining that the first equipment does not support the external equipment.
6. The method for expanding the device function according to claim 4, wherein the sending of the third network data with the data type of the instruction data type to the external device includes:
converting the third network data into message data;
and sending the message data to the external equipment through a preset protocol layer.
7. An external device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the method of any of claims 1 to 3 when executing the computer program.
8. A second device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, characterized in that the processor implements the method according to any of claims 4 to 6 when executing the computer program.
9. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the method according to any one of claims 1 to 3, or 4 to 6.
