Abstract

When an object file is to be transferred, a wireless communication device which supports a plurality of different protocols shortens a transfer time. The wireless communication device according to this invention includes a unit which receives object data, a unit which stores the received object data, and a unit which, when a predetermined amount of object data is stored, divides the object data into blocks, and transmits the object data to a wireless controller. The wireless communication device is characterized in that upon reception of the object data, the wireless controller monitors a reply interval of ACK to be replied, and changes, based on the reply interval, the amount of the object data to be stored.

Description

technical field [0001] The invention relates to a data processing technology for wireless communication. Background technique [0002] Based on the Bluetooth (Bluetooth) standard, OPP (Object Push Profile, Object Push Profile) is defined as a multipurpose communication profile for sending / receiving object data such as image data. In contrast, BIP (Basic Imaging Profile, static image transmission profile) has recently been developed as a communication profile dedicated to image data transmission. When BIP is used, various negotiations can be performed on the format, size, etc. of the image data to be transmitted. Also, the use of the BIP as a communication protocol subset in wireless transmission of image data between digital cameras and printer devices has also been studied. [0003] figure 2 is a schematic diagram showing a conventional Bluetooth wireless communication system. exist figure 2 In this example, the notebook PC 201 is connected to a Bluetooth device as a U...
