A Bluetooth Low Energy (BLE) mesh-based provisioning control method and system, and an electronic device. The method includes: the provisioner completes, within one interval scheduling cycle based on a preset ratio of effective transmission time to interval, interactive transmission of at least three data packets sent by the server; during provisioning between the provisioner and the to-be-connected device, the provisioner obtains current wireless access point information; the provisioner determines a target hopping channel value based on the current wireless access point information; after the to-be-connected device receives a connection request sent by the provisioner and sets the target hopping channel value as a to-be-connected device hopping value, the provisioner controls the to-be-connected device to hop at a frequency corresponding to the to-be-connected device hopping value to complete interaction of provisioning data packets.

Embodiments of the present invention provide a clock frequency modulation method and a clock frequency modulation apparatus. The method includes: determining N digital clocks according to a first digital clock of a system, where the N digital clocks includes a second digital clock and N-1 digital clocks except the second digital clock, and a sum of frequency ratios of the first digital clock to each of the N-1 digital clocks is equal to N-1 times a frequency ratio of the first digital clock to the second digital clock, where N is an integer greater than 2; and fitting, during a modulation period by using the N digital clocks, the first digital clock into the periodic second digital clock. The embodiments of the present invention use a clock frequency modulation technology to make energy concentrated in a frequency spread to a wider frequency range.
