Bluetooth Modules Q & A
Q: What's the typical lifespan of a Bluetooth module?
A: Quality modules last 3-5 years in continuous operation, with BLE versions often exceeding this due to lower power stress.
Q: How do I verify Bluetooth version compatibility?
A: Check the module's specification sheet for Bluetooth SIG qualification and version number (e.g., 5.2). Most modern modules maintain backward compatibility.
Q: What's the cost difference between Chinese and Western-made modules?
A: Chinese modules typically cost 30-50% less with comparable specifications, though lead times may be longer.
Q: Can I customize Bluetooth modules for my specific application?
A: Many Chinese manufacturers offer customization services for antenna design, firmware, and form factors at MOQs of 5,000+ units.
Q: How important is RF certification for my product?
A: Critical - uncertified modules may cause legal issues and performance problems in your target markets.
