Electronic device and method for transmitting packets for outputting audio, and non-transitory computer-readable recording medium

An electronic device, comprising:

• communication circuitry configured for Bluetooth low energy (BLE),
• at least one processor including processing circuitry, and
• memory comprising one or more storage media storing instructions, wherein the instructions, when executed at least one processor, individually and/or collectively, cause the electronic device to:
• generate a first connected isochronous group (CIG) event and a second CIG event to be used to output audio using an external electronic device,
• transmit a first packet according to a first transmission parameter, set for the first CIG event using the communication circuitry, to the external electronic device through a connected isochronous stream (CIS) event in the first CIG event, and
• transmit a second packet according to a second transmission parameter, set for the second CIG event using the communication circuitry, different from the first transmission parameter, to the external electronic device through a CIS event in the second CIG event.
