It can be seen that the data transmission method and the related product described in the embodiments of the present application are applied to a first neighbor awareness network NAN, and are configured to first acquire a second NAN device and a first transmission link in the first NAN, where the first transmission link is a transmission link for data transmission between the first NAN device and the second NAN device, then determine a first transmission quality value of the first transmission link, where the transmission quality value is used to indicate channel quality of the transmission link, then, if the first transmission quality value is lower than a preset threshold, select a second transmission link according to a preset transmission link update policy, where the second transmission link includes at least one NAN relay device in the first NAN, and finally, perform data transmission according to the second transmission link.

As can be seen, in the NAN network in this example, by connecting the first NAN device and the relay device and the channel between the relay device and the second NAN device, the smoothness and stability of data transmission are ensured.
In one possible example, before the transmitting data according to the second transmission link, the method further includes: matching the second transmission link with a preset white list to obtain a matching result; and if the matching result is successful, transmitting the second transmission link.
The preset white list can be obtained for the electronic device through a cloud or set by a manufacturer when the electronic device leaves a factory, and the preset white list is not limited uniquely here.
Optionally, if the matching result is failure, the second transmission link set is obtained again, and re-detection is performed.
