Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0049] Such as figure 1 As shown, the bluetooth information sending method of the present invention is used for the bluetooth host end of SPP agreement communication, comprises the following steps:

[0050] S1: Obtain data and buffer the data to be sent in a first-in-first-out mechanism;

[0051] S2: According to the length of the data to be sent, perform packetization or grouping operation on the buffered data to be sent to obtain at least one data packet;

[0052] S3: Send the packet over the established Bluetooth link.

[0053] The host end is a device set to SPP master mode, and the way to obtain data can be to receive data sent by external devices through the interface, or to collect data through the internal sensors of the host end. Such a...

Abstract

The invention relates to Bluetooth information sending and receiving methods in order to solve the problem that the security of Bluetooth data transmission cannot be guaranteed and the efficiency is low in the prior art. The Bluetooth information sending method of the invention, which is applied to a Bluetooth master computer carrying out communication based on SPP, comprises the following steps: S1, acquiring data, and caching to-be-sent data based on a first-in-first-out mechanism; S2, sub-packaging or packaging the cached to-be-sent data according to the length of the to-be-sent data to get at least one data packet; S3, sending the data packet through an established Bluetooth link. The Bluetooth information receiving method, which is applied to a Bluetooth slave computer carrying out communication based on SPP, comprises the following steps: S4, receiving the data packet through the established Bluetooth link; S5, reading the data in the data packet, and caching the data based on the first-in-first-out mechanism; and S6, sending the cached data to a memory in a segmented way.

Description

technical field [0001] The invention relates to the field of wireless communication, more specifically, to a method for sending and receiving bluetooth information. Background technique [0002] Bluetooth technology is an open specification for wireless data and digital communication. Due to its small size and low power consumption, the Bluetooth chip can be easily integrated into most digital devices to realize the interconnection between one device and multiple devices, so that various information devices can share resources. Bluetooth technology can be used in various fields such as mobile devices, personal data processing, headsets, printing devices, digital cameras, input devices, and wireless network access. [0003] As the application fields of Bluetooth technology expand day by day, the types of Bluetooth devices that support Bluetooth connection are also increasing. The SPP transparent transmission mode in Bluetooth technology is suitable for various short-distanc...
