In another implementation manner, the first bluetooth controller sends a first data packet obtained by scanning the first broadcast channel to the bluetooth module, after the bluetooth module determines the auxiliary information in the first data packet, the bluetooth module sends a scanning instruction to the first bluetooth controller, the scanning instruction carries a channel identifier and a target time, and the scanning instruction is used for instructing the second bluetooth controller to execute scanning on the first data channel, and the first bluetooth controller forwards the scanning instruction to the second bluetooth controller. In the implementation mode, the auxiliary information in the first data packet is determined through the Bluetooth module, the scanning instruction is synthesized through the Bluetooth module, and the auxiliary information is forwarded only through the first Bluetooth controller, so that the task amount of the first Bluetooth controller is reduced, and the first Bluetooth controller can be guaranteed to stably and efficiently execute channel scanning.

In the implementation mode, the scheduling module sends the channel identifier and the target time to the second Bluetooth controller, and the second Bluetooth controller can be instructed to execute scanning on the first data channel, so that the scheduling of the second Bluetooth controller is realized, the task amount of the first Bluetooth controller is reduced, and the first Bluetooth controller can be ensured to execute channel scanning stably and efficiently.
In another implementation manner, the first bluetooth controller sends a first data packet obtained by scanning a first broadcast channel to the bluetooth module through the scheduling module, and after the bluetooth module determines auxiliary information in the first data packet, the bluetooth module sends a scanning instruction to the second bluetooth controller through the scheduling module; and then can effectively realize controlling the second bluetooth controller to carry out the channel scanning through scheduling module for first bluetooth controller and second bluetooth controller can cooperate to carry out the scanning.
Step 304: the first electronic device instructs the second bluetooth controller to scan a target sub-channel corresponding to the channel identification at the target time to receive the second data packet from the second electronic device.
In some embodiments, the first electronic device sends a scan instruction carrying the channel identification and the target time to the second bluetooth controller, the scan instruction further for instructing the second bluetooth controller to scan the first data channel; specifically, the scanning instruction is used for instructing the second bluetooth controller to scan the target sub-channel corresponding to the channel identifier at the target time. Wherein the target sub-channel is at least one of the first data channels 0-36. Optionally, the target sub-channel can also be other channels than the 0-36 channel for transmitting the second data packet; for example, the other channel is at least one channel among 40-56 channels, which is not particularly limited in the embodiment of the present application. Optionally, the channel identifier is a channel sequence number or a channel frequency, etc.; in the embodiment of the present application, the channel identifier is not particularly limited.
In one implementation, after the first electronic device instructs the second bluetooth controller to receive the channel identifier and the target time, a scanning action is formulated based on the channel identifier and the target time, and the second bluetooth controller performs scanning based on the scanning action, that is, scans a target sub-channel corresponding to the channel identifier at the target time. The first electronic device scans the first data channel through the second Bluetooth controller to obtain a second data packet sent by the second electronic device through the first data channel.

With continued reference to fig. 4, fig. 4 is a schematic diagram of the first electronic device scanning a first broadcast channel and a first data channel through a first bluetooth controller and a second bluetooth controller, respectively; the first Bluetooth controller always keeps scanning the first broadcast channel, and the second Bluetooth controller scans the first data channel. The first electronic device performs periodic scanning on a broadcast channel, that is, scans the first broadcast channel once every preset time interval to generate a scanning window. In the figure, it can be seen that even if the second electronic device broadcasts the second data packet to the first electronic device through the first data channel, the first electronic device needs to acquire the auxiliary information pointing to the first data channel from the first data packet broadcast through the first broadcast channel, so that ensuring the scanning duration of the first broadcast channel is very important for acquiring the complete data packet.
In the embodiment of the application, the first electronic device can keep the first Bluetooth controller to scan the first broadcast channel under the condition that the second electronic device performs Bluetooth broadcasting through the first data channel to send the second data packet, and can also keep the first broadcast channel to obtain the first data packet broadcast through the first broadcast channel under the condition that the first electronic device can obtain the second data packet sent through the first data channel by performing scanning through the second Bluetooth controller, so that the condition that the first Bluetooth controller switches from the first broadcast channel to other channels to cause the first broadcast channel to have short scanning time is avoided, and the scanning performance of the first Bluetooth controller to the first broadcast channel is improved.

step 701: the first electronic device performs scanning of the first broadcast channel via the first bluetooth controller to receive the first data packet from the second electronic device.
This step is similar to step 301 and will not be described again here.
Step 702: the first electronic device maintains a scan of the first broadcast channel by the first bluetooth controller based on determining that the second electronic device establishes a bluetooth communication connection with the first electronic device to use the first data channel, and performs a scan of the first data channel by the second bluetooth controller to receive second data packets from the second electronic device.
