As cars evolve into connected environments, the pressure on wireless systems increases. Passengers now expect to run audio, gaming controllers, tablets and wearables in parallel without fighting for bandwidth or interrupting each other’s streams. Traditional combo modules often struggle here because they top out after a few simultaneous links. u-blox has stepped into this gap with JODY-B1, an automotive Bluetooth module built to maintain multiple independent Classic and LE connections inside a single cabin without adding system complexity.
Multi Device Connectivity for In Car Systems
The main engineering appeal of JODY-B1 lies in its ability to sustain several Bluetooth links at once. Each connection can operate independently, which is valuable in vehicles where front and rear zones serve different functions. A headset in the back seat should not interrupt a controller or phone connected up front, and gaming peripherals must respond quickly even when the audio system is handling its own traffic. This module is designed to remove those constraints, making personalised in car interaction practical across multiple occupants.
Technical Foundation Built for Automotive Conditions
JODY-B1 is built on Qualcomm’s Snapdragon Auto Connectivity Platform and the QCA8695AU chipset, giving it the thermal range and electrical behaviour needed for cabin integration. The module supports both Classic and LE modes, including LE Audio, and is qualified up to 105 degrees Celsius. Its 13.8 by 19.8 millimetre footprint means engineers can place it into tight layouts, often without changing existing mechanical constraints. A host based UART keeps the interface simple, and its global certifications reduce the need for extensive radio testing during development. In practice, it behaves like a drop in radio subsystem with predictable performance across vehicle temperature cycles.
Integration Pathways for Tier 1 and OEM Platforms
For engineers evaluating system level design, the ease of integration stands out. Because the module is pre certified for major markets and Bluetooth SIG compliant, the radio section becomes a solved problem. Developers can focus on software control of multiple Bluetooth instances rather than managing RF coexistence or antenna layout complexities. The consistency with previous JODY family modules also matters for teams already using u-blox hardware, since it helps maintain mechanical, driver and qualification continuity. This reduces project risk and shortens validation cycles.
Broader Implications for Connected Cabin Architectures
The move toward multi device wireless ecosystems inside vehicles is only accelerating. As more infotainment domains split into independent zones, and as gaming and productivity features enter the cabin, Bluetooth capacity becomes a limiting factor. Modules like JODY-B1 point toward a future where vehicles treat wireless peripherals the same way consumer devices do, with each passenger able to run their own experience without contention. For engineers, it signals a shift toward higher connection density and more modular RF subsystems in next generation cabin designs.
