The automotive landscape is shifting. While luxury vehicles enjoy high-end Linux/Android cockpits, the massive market of two-wheelers, three-wheelers, and cost-efficient EVs has often been left behind due to hardware limitations. Embien changes the game with the RAPIDSEA Automotive Navigation and Connectivity Stack.
We understand that modern riders demand seamless connectivity, regardless of the vehicle segment. Our stack empowers OEMs and Tier 1s to provide a premium, smartphone-tethered experience on low-cost Instrument Clusters (IC). By offloading processing power to the user's smartphone via BLE and Wi-Fi, RAPIDSEA enables rich infotainment features on standard microcontrollers (MCUs) without the need for expensive application processors.
RAPIDSEA operates as a bridge, utilizing optimized Bluetooth Low Energy (BLE) profiles to turn the cluster into an extension of the ride's digital life. Compatible with UART/SPI interfaces and leading chipsets (TI, Microchip, Renesas, Nordic, ESP32), our stack delivers:
Safely display SMS, WhatsApp, and 8+ popular social and messaging app alerts directly on the dashboard.
Caller ID display with handlebar controls to Accept, Reject, or Silence calls.
Full music metadata (Song, Artist, Album) display with Play/Pause/Skip controls.
Access the phone's contact list directly from the cluster and initiate calls without touching the smartphone.
Lock or unlock the vehicle directly from the mobile app through the connected cluster.
One-touch redialing for the last dialed number for quick communication.
Securely transfer and view vehicle documents from the mobile app on the cluster.
Update UI themes & brightness levels via mobile app for personalized visibility in all riding conditions.
Navigation is no longer a luxury; it is a necessity. RAPIDSEA’s Small Footprint Automotive Navigation Stack brings global positioning to the most basic displays.
