Abstract

A portable recording device may use a low-energy transceiver to communicate with a computing device in order to activate a high-energy communication connection with the computing device for exchanging data. The portable recording device may initially broadcast a device identifier of the portable recording device via the low-energy transceiver. The portable recording device may then connect to a computing device via a high-energy communication connection that is formed using a high-energy transceiver of the portable recording device. The computing device may be triggered to initiate a formation of the high-energy communication connection with the portable recording device by the device identifier broadcasted using the low-energy transceiver. Subsequently, the portable recording device may send data files to the computing device via the high-energy communication connection. The data files may include a data asset that is captured by the portable recording device or metadata for the data asset.
