Abstract: 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.
