Communication Device BLE Advertising for Timely Error Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for devices like printers often face inconvenient timing for error notification after switching to high-speed data communication, which can delay user awareness of issues such as ink shortages or sheet jamming.
Innovation Solution
A communication system that uses a combination of Bluetooth Low Energy for initial advertising and connection requests, allowing for timely notification of device states through GATT communication, ensuring secure and convenient error information dissemination to connected information processing devices.

Engineering Contradiction Analysis
1Speed
If error notification is performed after switching to high-speed communication for print job transmission, then data transmission speed is improved, but notification timing becomes inconvenient and delayed
Solution Approach 1:
The notification function is segmented into two independent communication channels: real-time status notification via Bluetooth Low Energy and high-speed data transmission via Wi-Fi. This allows error notifications to be sent immediately through BLE without waiting for the print job to complete or switch communication protocols, while still utilizing high-speed communication for actual print data transmission.
Solution Approach 2:
The system establishes a notification communication channel via Bluetooth Low Energy before initiating the print job. This preliminary setup ensures that the notification pathway is already active and can immediately transmit error status information without requiring protocol switching or connection re-establishment when errors occur during printing.
2Speed
If wireless connection is established by NFC and then switched to high-speed communication, then connection speed is improved, but error notification timing becomes inconvenient
Solution Approach 1:
The communication system is segmented into two distinct functional layers: a fast connection establishment layer using NFC, and a persistent real-time notification layer using Bluetooth Low Energy. The BLE connection remains active independently throughout the printing process, ensuring continuous error notification capability without requiring protocol switches or additional user actions.
Solution Approach 2:
The Bluetooth Low Energy connection serves multiple functions simultaneously: it maintains device pairing information, provides continuous error status notifications, and can serve as a fallback communication channel. This multi-functionality ensures that error notifications are always available regardless of the state of high-speed communication channels.

AI summary
A communication system includes a communication device that communicates with an information processing device. The communication device wirelessly communicates via a first communication format and a second communication format, which is faster than the first communication format. The communication device includes a broadcasting unit that broadcasts advertising information via the first communication format, and a transmission unit that transmits status information relating to a state of the communication device to a certain information processing device via communication established based on a connection request from the certain information processing device, based on the advertising information. The certain information processing device performs notification of information indicating the state of the communication device based on the transmitted status information.
