Abstract

The communication system comprises an image module and a host. The host initializes and controls the image module by sending control commands thereto and each control command comprises a plurality of sub-commands. The sub-commands are transmitted to the image module in sequence. Then, the image module processes the sub-command and returns an ACK to the host. When completely sends all sub-commands of a control command out, the host checks the feed-back ACKs, if the feed-back ACKs are fault, then resends the sub-commands of the control command in sequence. Therefore, the host no longer wastes time on waiting an ACK before sending another sub-command. As a result, it cuts delay down and improves transmitting efficiency of the wireless communication system.

Claims

1. A method for transmitting real time image data of wireless communication system, said image data transmitted from an image module to a host, said host controlling said image module to capture image and send image module data back to said host upon the correspondence of control command, the control command having a plurality of sub-commands for the correspondence, the process for transmitting said control command from said host to said image module comprising the steps of:

a. transmitting said sub-commands of said control command from said host to said image module in sequence;

b. processing said sub-commands received and returning an acknowledgement to said host by said image module;

c. when completely sending out all sub-commands, checking said acknowledgements received by said host, if said acknowledgements represents fault, then resending the sub-commands of said control command in sequence.

2. The method for transmitting real time image data of wireless communication system as claimed in claim 1, wherein said host and said image module establishes wireless communication by Bluetooth SPP technology.

3. The method for transmitting real time image data of wireless communication system as claimed in claim 1, wherein said host installs a control program for initializing and controlling said image module.

4. The method for transmitting real time image data of wireless communication system as claimed in claim 1, wherein said sub-command is carried by a data packet.

5. The method for transmitting real time image data of wireless communication system as claimed in claim 1, wherein said host is an electronic device.
