Making Sewing Machines Talk: KT1025A Bluetooth Voice Chip Enables Easy Human - Machine Interaction

 With the continuous development of technology, modern life is becoming increasingly intelligent, and sewing machines are no exception. The intelligence of sewing machines not only makes them more convenient and faster for users but also improves sewing quality and efficiency. To further enhance the intelligence of sewing machines, many sewing machine manufacturers have started to apply voice - broadcasting chips to sewing machines to improve user experience and usage efficiency. The KT1025A Bluetooth voice chip developed by Shenzhen Qingyue Electronics is a standout among them.

The KT1025A chip is designed specifically for audio applications. It is a high - quality full - format voice codec chip for MP3, WAV, WMA, FLAC, AAC, and APE developed by Shenzhen Qingyue Electronics. The chip adopts an SOC solution, integrating a 32 - bit MCU, a powerful aDSP (Digital Signal Processor) core specifically for audio decoding, and a 24 - bit DAC. The hard - decoding method ensures the stability of the system and sound quality. It accesses and exchanges data with external devices through the UART interface. It has rich peripheral interfaces, is easy to operate, and its small package size better meets the needs of being embedded in various different products.

Features of the KT1025A Audio Bluetooth Chip

1. Supports Bluetooth audio, BLE data transmission, U - disk playback, TF - card playback, and SPI Flash. Supports MP3, WAV, FLAC, APE format decoding.

2. Serial port AT command control. Supports modifying the baud rate, Bluetooth name, specifying device playback, and transparent transmission of phone data.

3. Supports BLE and SPP dual - mode data transmission while simultaneously playing Bluetooth audio without conflict.

4. Supports Bluetooth calls, multi - button control (previous track, next track, play/pause, volume adjustment, etc.) for simple functions.

5. Supports retrieving the full filename of the played file, serial - port - specified path playback, and loop or single playback.

6. Supports a 128Kbps recording function. Records to a TF card or U - disk, with options for recording deletion and playback.

7. Rich usage materials, including reference PCB, usage video tutorials, phone transparent transmission video tutorials, and serial port AT video tutorials.

8. Ultra - low cost, with a competitive price for large quantities, and a very simple peripheral circuit requiring only 5 capacitors.

9. Easily integrates with existing apps or supports the development of WeChat mini - programs for phone control.

10. The functional firmware is developed in - house, highly flexible, and open to discussion for developing features that do not meet current needs.

The application of the KT1025A audio Bluetooth chip solution in smart sewing machines can enable sewing machines to automatically broadcast working status, machine faults, and other information. Users can easily understand the working status of the sewing machine, such as running out of bobbin thread or thread breakage, avoiding unnecessary losses such as time waste and poor sewing results caused by not paying attention to the problems of the sewing machine in a timely manner. At the same time, the KT1025A has a Bluetooth transmission function that complies with the Bluetooth 5.0 specification, providing users with a more intelligent and easy - to - operate sewing machine experience.

KT148A Voice Chip Issue: Difficult to Play with Code Sending - Normal Playback After Grounding Pin 4, What’s the Reason?

图片
Problem Description: Hello, we’ve encountered an issue and would appreciate your support: With the KT148A chip, after powering on, sending the code rarely triggers playback. However, if we use tweezers to briefly short Pin 4 (PB0) to ground and then send the code again, playback works normally. What could be causing this? Based on the observed behavior, it’s highly likely an issue with the timing of one-wire communication,  particularly with the start signal, which may be too short.  Let’s analyze this in detail and review the KT148A schematic as follows: 1. Pin 4 (PB0) of the Chip: PB0 is a test pin with the default factory function of triggering wake-up and playback when grounded. 2. Customer Description: When the customer uses tweezers to short PB0 (Pin 4) to ground, it follows this principle. The shorting action actually performs two operations: Action 1: The KT148A detects a falling edge signal, wakes up, exits low-power mode, and enters full-speed operation. Action 2: Th...

KT1025A Dual-Mode Bluetooth Audio Chip Layout Description and Design Precautions

图片
  1. Brief Overview 1. First, please refer to the provided BT201 test DEMO module as the standard. 2. If using the chip independently without testing the BT201 module and directly proceeding to layout, background noise is highly likely if experience is limited. Therefore, always compare with the manufacturer’s test board first. 3. The BT201 solution does not include FM functionality. Please note this. The FM circuit should be left floating without hesitation 2. Precautions 1. Background noise or interference is common in Bluetooth audio products. Do not be careless during layout. 2. If you have not worked on audio products before, study online resources thoroughly. Assuming things casually will naturally lead to noise issues. 3. The core principle is to separate analog ground and digital ground. If unclear, consult an experienced engineer. 4. Ensure a clean power supply. Use an LDO whenever possible instead of a DC-DC converter. 5. Bluetooth operates at high-frequency RF and radiat...
