[0071] S1. Initialize the RAM, and then initialize each external device and software protocol;

[0072] S2. The slave device detects whether the broadcast information to be sent is legal, and if so, executes step S3; otherwise, does not process the broadcast information;

[0073] S3. The slave device detects the state of the transmission channel, and if the transmission channel is in an idle state, sends the broadcast information; if the transmission channel is in a busy state, waits for a delay period and then detects the state of the transmission channel again from the device.

[0074] S4. Detect whether the broadcast information from the slave device is received, if so, execute step S5; otherwise, execute step S6;

[0075] S5. Discover the slave device according to the received broadcast information, and send networking information to the slave device to configure the network, and then perform step S6; wherein, the slave device can be configured by the master device, once t...

Abstract

The invention discloses a self-networking method and a self-networking system based on the bluetooth technology. The self-networking method comprises the steps that: an RAM is initialized, and then external equipment and software protocols are initialized; slave equipment transmits broadcast information through a multi-equipment automatic avoidance algorithm; master equipment enters a broadcast receiving stage, and transmits networking information to the slave equipment for networking configuration. The self-networking system comprises an initialization unit, a broadcast transmitting unit and a networking unit. The self-networking method and the self-networking system can effectively reduce power consumption, do not need a gateway, adopt the broadcast technology, can greatly increase the distance between nodes, can transmit signals to farther places continuously after utilizing the relaying function of a chip, and are convenient and easy to use; in addition, the self-networking method and the self-networking system adopt the multi-equipment automatic avoidance algorithm for transmitting broadcast information, can effectively avoid collision and conflict in communication, make the operation of the whole network more stable, greatly improves the networking efficiency and stability, and can be widely used in the bluetooth self-networking technology.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an ad hoc network method and system based on bluetooth technology. Background technique [0002] Bluetooth is a radio technology that supports short-range communication between devices (typically within 10m). It can carry out wireless information exchange between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The Bluetooth standard is IEEE802.15, which operates in the 2.4GHz frequency band and has a bandwidth of 1Mb / s. After several years of development, we are no longer unfamiliar with it, and it is also an indispensable module in current digital products. The emergence of Bluetooth technology allows us to no longer be bound by numerous data lines when connecting various devices, such as stereos, computers, mice, keyboards, and even cars. This technology is the simplest and most convenient method for w...
