Electronic device for transmitting response message in bluetooth network environment and method thereof

An electronic device comprising:

• a wireless communication circuit configured to support a Bluetooth network;
• at least one processor;
• and
• a memory,
• wherein the memory is configured to store instructions that, when executed by the at least one processor, cause the electronic device to:
• generate a first link with a first external electronic device based on the Bluetooth network,
• receive information related to a second link generated between the first external electronic device and a second external electronic device from the first external electronic device,
• negotiate timing for transmitting a response message to the second external electronic device with the first external electronic device based on at least one of functions of a master device and a slave device, a battery status of the electronic device and the first external electronic device, or a type of the response message, wherein the timing comprises a first timing and a second timing corresponding to a timing later than the first timing by a specified time,
• attempt to receive a data packet transmitted from the second external electronic device by monitoring the second link based on at least a piece of the information related to the second link,
• refrain from transmitting the response message when the data packet is normally received, and
• transmit the response message indicating a negative acknowledgement (NACK) to the second external electronic device the negotiated timing.
