Electronic device and associated control method

An electronic device, comprising:

• a processing circuit;
• and
• a wireless communication module;
• wherein the wireless communication module is configured to perform the steps of:
• generating a media access control (MAC) frame;
• performing a specific encoding operation on a specific field of the MAC frame to generate a parity;
• using the parity to replace part of content of the specific field;
• and
• generating a packet according to the MAC frame for sending to another electronic device.

A control method of an electronic device, comprising:

• receiving a packet from another electronic device;
• determining whether a specific field of a media access control (MAC) frame of the packet is generated by a specific encoding method;
• if the specific field of the MAC frame is generated by the specific encoding method, determining that a vendor of the another electronic device and a vendor of the wireless communication module in the electronic device are the same;
• and
• if the specific field of the MAC frame is not generated by the specific encoding method, determining that the vendor of the another electronic device is different from the vendor of the wireless communication module in the electronic device.
