Bluetooth Transmitter Feedback Mechanism for Reliable Data Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth communication systems lack the ability to confirm successful data package reception by receivers and cannot dynamically adjust broadcasting based on receiver requests, leading to inefficiencies in data transmission and quality control.
Innovation Solution
A Bluetooth communication system that detects multiple receivers within its range, broadcasts data packages during designated timing windows, and receives acknowledge messages from receivers, allowing for adjustments in broadcasting operations based on the feedback included in the returned data packages, which includes an address, category, flow, reply, and sequentially numbering fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Bluetooth transmitter broadcasts data packages without feedback mechanism, then the broadcasting operation is simple, but the transmitter cannot confirm successful reception and cannot dynamically adjust broadcasting
Solution Approach 1:
The patent implements a feedback mechanism where Bluetooth receivers send returned data packages containing acknowledge messages to the transmitter. The transmitter detects these feedback signals to confirm successful reception of broadcast data packages, enabling reliable communication while maintaining relatively simple protocol structure through structured header fields.
2Adaptability or versatility
If Bluetooth transmitter uses pre-defined broadcasting manner, then the broadcasting operation is simple to implement, but it cannot respond to unexpected receiver requests
Solution Approach 1:
The patent enables dynamic broadcasting control by allowing the transmitter to adjust its broadcasting operation based on real-time feedback from receivers. The system transitions from static pre-defined broadcasting to dynamic adaptive broadcasting, where the transmitter can modify parameters such as re-broadcasting decisions based on received acknowledge messages and receiver requests.
3Reliability
If Bluetooth transmitter re-broadcasts data packages multiple times based on experience, then coverage is improved, but the number of re-broadcasts cannot be precisely controlled
Solution Approach 1:
The patent replaces experience-based re-broadcasting decisions with feedback-driven control. The transmitter receives acknowledge messages from receivers indicating successful data package reception, allowing it to precisely determine when re-broadcasting is necessary. This eliminates unnecessary re-broadcasts and optimizes broadcasting time while ensuring reliable delivery.

AI summary
A blue-tooth communication system and a broadcasting method therefor are provided. The broadcasting method includes: detecting N blue-tooth receivers in a blue-tooth range of a blue-tooth transmitter; broadcasting a data package during at least one transmitting timing window by the blue-tooth transmitter; and receiving N returned data packages which are respectively returned by the corresponding blue-tooth receivers by the blue-tooth transmitter during N receiving timing windows. At least one of the N returned data packages includes an acknowledge message which is recorded in a header field of the corresponding returned data package.
