Electronic device for transmitting voice data, and operation method thereof

An operation method of an electronic device, the operation method comprising:

• establishing communication with an external electronic device;
• configuring a first type of packet for transmission or reception of voice data through negotiation with the external electronic device;
• transmitting first voice data to the external electronic device based on the first type of packet;
• receiving, from the external electronic device, second voice data of the first type of packet and reception failure information corresponding to the first voice data;
• based on the receiving the reception failure information corresponding to the first voice data from the external electronic device, transmitting third voice data corresponding to the first voice data to the external electronic device based on a second type of packet having a higher transmit power than the first type of packet;
• decoding the second voice data;
• and
• transmitting information corresponding to reception of the second voice data to the external electronic device.

An electronic device comprising:

• a communication circuit;
• memory storing at least one instruction;
• and
• at least one processor operatively coupled to the communication circuit,
• wherein the at least one instruction, when executed by the at least one processor individually or collectively, causes the electronic device to:
• establish communication with an external electronic device through the communication circuit;
• configure a first type of packet for transmission or reception of voice data through negotiation with the external electronic device;
• transmit first voice data to the external electronic device based on the first type of packet;
• based on receiving reception failure information corresponding to the first voice data from the external electronic device or not receiving reception information corresponding to the first voice data from the external electronic device, transmit second voice data to the external electronic device based on a second type of packet different from the first type of packet;
• and
• based on receiving reception failure information corresponding to the second voice data from the external electronic device, transmit third voice data to the external electronic device based on the first type of packet.
