This application provides a communication method and apparatus, relating to the field of communication technology. The method includes: after a first walkie-talkie device is powered on, it begins scanning for surrounding devices. When a second low-power Bluetooth broadcast established by a second walkie-talkie device of the same type is detected within a preset time period, the first walkie-talkie device synchronously scans the second low-power Bluetooth broadcast and establishes its own first low-power Bluetooth broadcast. In this state, the first walkie-talkie device sends voice data to the second walkie-talkie device via the first low-power Bluetooth broadcast, and obtains the voice data sent by the second walkie-talkie device by scanning the second low-power Bluetooth broadcast. That is, the first walkie-talkie device can receive voice data broadcast by the second walkie-talkie device, and the first walkie-talkie device can also directly broadcast the collected voice data, realizing full-duplex communication between the walkie-talkie devices, thereby improving the efficiency of voice calls and bringing convenience to users.
