Bluetooth Empowering the Smart Cockpit Co-Pilot Screen

With the rapid development of automotive technology, Bluetooth has always been one of the most important companions of in-vehicle innovation. It not only enables drivers and passengers to enjoy hands-free calls for safer driving but also makes wireless music playback a standard feature for in-car entertainment, creating a comfortable and enjoyable driving atmosphere. When combined with the co-pilot screen, Bluetooth brings passengers an entirely new experience.

Application Needs of the Co-Pilot Screen

• Entertainment Needs:
  During long trips, passengers expect to watch high-definition movies, TV shows, and other video content on the co-pilot screen to ease the boredom of travel. They can also select their favorite music through the screen and enjoy a high-quality audio experience. In leisure time, simple games such as racing, poker, or casual board games can be played using the touchscreen or Bluetooth game controllers.
• Information Interaction Needs:
  The co-pilot screen can display real-time navigation maps and route planning. Co-pilots can assist drivers by checking road conditions and planning ahead. In case of traffic congestion, routes can be adjusted promptly to improve travel efficiency. The screen can also display vehicle status such as speed, fuel consumption, and tire pressure, enhancing passengers’ understanding of the vehicle and improving driving safety.

Bluetooth Adaptation for Co-Pilot Screens

• Key Hardware Considerations:
  The co-pilot screen and Bluetooth device must ensure interface compatibility, such as USB, HDMI, I2S, or Analog. Without matching interfaces, physical connections and data exchange cannot be achieved. Power coordination is equally important, as it affects connection distance, certification requirements, and user experience. Furthermore, size and specification matching directly impact PCB layout, structural design, and performance parameters of the co-pilot screen.
• Connection Method:
  Bluetooth pairing is the basic way to connect the co-pilot screen with other devices. Users only need to enable Bluetooth on both sides, search, and pair successfully. Once paired, devices are stored in the pairing list for flexible switching. If disconnected, the screen can automatically recognize and reconnect devices within range.
• Testing Process:
  Bluetooth testing includes verifying quick and stable connections, checking audio transmission quality for clarity and absence of noise, and ensuring smooth video transmission if supported. Performance indicators focus on stability over long-term connections, transmission speed, and response time. Compatibility testing is crucial—some automakers, for example, require compatibility with the top 30 bestselling headphones on JD.com.

Application Practices

• Automaker A:
  The main audio source is delivered to the FSC-BT1035 module via I2S, and then the Bluetooth module transmits audio to Bluetooth headphones. Powered by Qualcomm’s QCC3056 chip, the module supports simultaneous connection of two headphones and both onboard and external antennas, ensuring compatibility with various hardware structures. It has been tested with the top 30 bestselling headphones in both China and South Korea.
• Automaker B:
  The FSC-BT1211 Bluetooth module works with the MT8676 main SoC, with the Bluetooth stack integrated directly into the SoC. Audio data is transmitted via UART, and high-quality calls can also be routed through PCM. This solution supports two Bluetooth headphones, Bluetooth controllers, and the latest LE Audio technology, enabling true multi-zone sound output.

Future Development Trends

• Technical Upgrades:
  Bluetooth versions and data rates are closely linked, and future versions will see significant improvements. Stronger anti-interference through new coding and modulation techniques will ensure stable performance even in complex electromagnetic environments. Low latency is especially critical for real-time applications, and Bluetooth delay will continue to decrease. For instance, Feasycom’s FSC-631D and FSC-BT2054RV modules already support LE Audio low-latency technology.

• Market Outlook:
  According to automakers’ plans, more brands are prioritizing Bluetooth-enabled co-pilot screens as a key feature. Leading domestic car manufacturers plan to make it a standard feature in future models, many of them already adopting FSC-BT1211 or FSC-BT2054RV modules. Market demand is shifting toward richer functions and better user experiences, such as customized applications, gaming, video streaming, music, monitoring, and safety alerts. Industry forecasts predict continuous growth in this sector. With technological maturity and cost reductions, Bluetooth-enabled co-pilot screens are expected to become standard across all new energy vehicles, delivering smarter, more convenient, and more enjoyable driving experiences.
