Bluetooth Jobs

I’m ready to move a new consumer-electronics wearable from concept to production and need an experienced PCB designer who can take charge of a compact, multi-layer board. The board must seamlessly combine robust power management, reliable wireless communication (Bluetooth / BLE is preferred), and precise sensor integration for motion and biometric data. You’ll start from my preliminary schematic notes and block diagram, refine the circuitry for a 4–6-layer stack-up, and optimise the layout for low power, tight space, and signal integrity. Please keep antenna placement and ground-plane strategy top of mind so the wireless link stays clean even inside a small wearable enclosure. I’m comfortable with Altium Designer, KiCad, or Eagle files—choose whichever tool...

I need a single mobile application that runs smoothly on both iOS and Android and pairs with an ODB-II Bluetooth dongle. Once connected, the app must read live vehicle data, pull stored error codes with human-readable descriptions, and generate maintenance reminders based on mileage or running hours. Connection should happen automatically as soon as the phone detects the paired dongle; no manual VIN or parameter entry is expected. For users who prefer it, the same information can be imported from an existing test report file, so I’ll need a simple file-picker flow that parses that report and displays the results exactly as if they came from the live Bluetooth session. All customer details—name, contact info, vehicle profile, past scans—stay inside the app’s ow...
