Job description

Embedded Software Engineer BLE over CAN Integration for RV-Screen

About the Project

We are upgrading the communication system of a new TFT touchscreen (RV-Screen) this is a user interface to control recreational vehicles such as caravans and motorhomes. The current system uses Bluetooth Low Energy (BLE) to communicate between a user-facing Android tablet and an embedded electronics control unit (Node), with certain features managed via a physical interface over a CAN Bus network. To improve reliability and resolve intermittent BLE connectivity issues, we're moving to the new RV-Screen with native CAN support. The new solution will reroute existing BLE communication through the CAN Bus network using the Recreational Vehicle CAN Bus (RV-C) protocol.

Role Overview

As an Embedded Software Engineer, you will be crucial in redesigning the communication architecture for the new system. Your role will involve splitting BLE packets (up to 21 bytes) to fit the 8-byte capacity of RVC frames, managing packet transmission and reassembly, and ensuring that BLE-specific events (e.g., connections, disconnections, characteristic discovery) are correctly communicated over RVC.

Key Responsibilities

Develop mechanisms for BLE packet fragmentation, transmission, and reassembly over the RVC network.
Integrate necessary metadata (message type, size, handle) within RVC frames for reliable message reconstruction.
Implement protocols to communicate BLE events over RVC, ensuring seamless integration.
Test and validate the new communication system, focusing on eliminating previous BLE connectivity issues.

Who We're Looking For

We need a skilled Embedded Software Engineer with experience in:

Bluetooth Low Energy (BLE) communication protocols.
CAN Bus especially in embedded automotive or recreational vehicle systems.
Data packet fragmentation and reassembly.
Designing and implementing robust communication protocols for embedded systems.
Coding in C language on the (Node) and C++ on the (RV-Screen)

Why Join Us?

You'll have the opportunity to work on a high-impact project that enhances the functionality of a leading-edge RV product, solving real-world problems while pushing the limits of embedded software and systems integration. If you enjoy tackling complex challenges and have a passion for embedded technology, we want to hear from you!
