Regarding the compatibility strategy for Bluetooth modules between different devices, there are several key points to note:

1. Bluetooth version and protocol: For example, Quectel Communications' DynaBlue protocol stack supports Bluetooth 6.1 and is compatible with Bluetooth Low Energy and LE Audio, which are important for multi-device connectivity. This may mean that using a newer Bluetooth version improves compatibility.

2. Connection stability: Mengxun Electronics' automated testing patent may involve testing the stability of Bluetooth modules to ensure reliable connections between different devices. Users may need to pay attention to the module's testing and certification status.

3. Power management: Weishuo's WST2011 MOSFET, used in smart wearable devices, emphasizes low power consumption and high performance, which helps the Bluetooth module's battery life. Wearable devices generally require high battery life, so a Bluetooth Low Energy module is essential.

4. Audio transmission: Sony's new gaming speakers support PlayStation Link technology, providing lossless wireless connection and ultra-low latency, which is important for scenarios requiring high sound quality and synchronization. Users may also need to consider support for audio codecs such as aptX or AAC.

5. Hardware Compatibility: LG's older speakers support Bluetooth and NFC, but may face compatibility issues, especially with newer devices. Users need to confirm that the Bluetooth version and features supported by their devices match.

6. Price Factor: Bluetooth modules vary widely in price, ranging from budget speakers like Newman to high-end Huawei models. Users may need to choose the right module based on their budget.

Next, I need to organize this information into a structured guide, covering compatibility key points, purchasing recommendations, and FAQs. This will ensure that the different needs of phones, speakers, and wearables are addressed. For example, phones prioritize connection stability and compatibility, speakers focus on sound quality and power, and wearables emphasize low power consumption and battery life.

Also, potential issues users may encounter include unstable connection, high latency, and poor compatibility. Specific solutions need to be provided, such as updating firmware, using the same Bluetooth version, and disabling interfering devices. Users should also be reminded of certification standards, such as BQB certification, to ensure that the module meets industry specifications.

Finally, I will summarize key points, emphasizing the importance of choosing the right Bluetooth version, paying attention to power consumption, testing compatibility, and utilizing the latest technologies. Ensure your answers are clear, practical, and based on the provided knowledge base content.

The following is a guide to adapting Bluetooth modules to mobile phones, speakers, wearable devices, and other scenarios, combining technical features with actual application requirements:

I. Key Points for Bluetooth Module Adaptation

1. Bluetooth Version and Protocol Compatibility

Bluetooth Version: Ensure that the Bluetooth versions of your phone, speaker, and wearable device are consistent or compatible (e.g., Bluetooth 5.3, Bluetooth 6.1).
For example, the Xiaomi REDMI Bluetooth Speaker 2 supports Bluetooth 5.3 and is compatible with mainstream phones; the Sony Pulse Elevate speaker supports lossless wireless transmission (requires a PS5 or compatible device).
Protocol Stack: Choose a protocol that supports multiple platforms (e.g., Quectel's DynaBlue protocol stack, which is compatible with Linux/Android systems and multiple chip platforms).
LE Audio: If low-power audio transmission is required (e.g., for smart headphones), prioritize modules that support LE Audio (e.g., the Quectel DynaBlue).

2. Power Consumption and Battery Life Optimization

Low-power Design: Wearable devices (e.g., fitness trackers) should use low-power Bluetooth modules (e.g., the Micro-Shuo WST2011 MOSFET) to reduce standby power consumption. Battery Capacity: Speaker devices require a large-capacity battery (e.g., the REDMI Bluetooth Speaker 2 has a built-in 1000mAh battery with a 5-hour battery life).

3. Connection Stability and Interference Resistance

Environmental Interference: Avoid co-channel interference with devices such as WiFi and microwave ovens. Use antenna optimization technology if necessary.

Automatic Testing: Ensure module stability using a Bluetooth module automatic testing system (e.g., patented technology from Mengxun Electronics).

4. Audio Transmission Quality

Codec: Support for high-quality audio codecs (e.g., aptX and AAC) can improve speaker sound quality (e.g., Sony LinkBuds).

Latency Control: Low-latency technology is required for gaming and video playback (e.g., PlayStation Link technology in the Sony Pulse Elevate).

II. Adaptation Strategies for Different Scenarios

1. Pairing a Phone with a Bluetooth Speaker

Steps:

1. Turn on your phone's Bluetooth and enter pairing mode (e.g., for the REDMI Speaker 2, press and hold the power button for 3 seconds).

2. Search for the device name (e.g., "REDMI Bluetooth Speaker 2") and tap Connect.
3. Verify audio transmission (play music to test sound quality and latency).
Note:
If the connection fails, check whether your phone's Bluetooth driver is updated (some Android phones require manual updating).
When switching between multiple devices, prioritize turning off other Bluetooth devices to reduce interference.

2. Connecting a wearable device with a phone/speaker

Health monitoring scenario:
A wearable device (such as the Silver Hair smart bracelet) uploads heart rate and blood pressure data to a mobile app via Bluetooth. Ensure that the module supports low-power transmission.
Voice interaction scenario:
The Sony Pulse Elevate integrates an AI noise-canceling microphone and supports voice calls without headphones. Bluetooth audio sharing must be enabled on the phone.

3. Multi-device collaboration (such as a speaker + phone + PC)

Multitasking:
Use LE Audio's multi-device concurrency feature (such as Quectel DynaBlue) to simultaneously connect to the speaker for music playback and phone calls to avoid disconnection. Cross-platform compatibility: Choose a speaker that supports multiple operating systems (Windows/Mac/Android/iOS) (such as the STEWPIGO 4th Generation Plus).

III. Purchasing Recommendations

1. Prioritizing Value:

The Newman BT15 Bluetooth Speaker (32.22 yuan) meets basic sound quality needs;

The STEWPIGO 4th Generation Plus (80 yuan discount) balances sound quality and portability.

2. High-End Experience:

The Huawei Sound X4 (1571.65 yuan) offers immersive sound and smart home integration;

The Sony Pulse Elevate (available in 2026) is designed for gaming and multitasking.

3. Technical Verification:

Preferably choose modules that have passed BQB certification (such as Quectel DynaBlue) to ensure protocol compliance.

For wearable devices, refer to the "simple operation + core functions + long-lasting battery life" standard proposed by Bairuiying.

V. Future Trends

1. LE Audio Popularization: Multi-device audio sharing and broadcast audio (such as in conference scenarios) will become mainstream.
2. AI Integration: Little Sea Monster's intelligent interactive patent indicates that the Bluetooth speaker will integrate interactive features such as motion recognition and 3D animation linkage.
3. Age-friendly Design: Large buttons, dialect voice interaction, and one-touch emergency calls will become standard features for senior-friendly devices.
