Bluetooth Low Energy (BLE) Jobs

I want to turn a standard RC chassis into a smart, self-aware toy that can do far more than just follow joystick commands. The end goal is a prototype car that: • Detects obstacles in real time • Plans an optimal path around them • Switches between full autonomous driving and classic “manual” mode on demand Everything should be directed from a single mobile app that works seamlessly on both iOS and Android. From that app I need to: 1. Watch a live video feed (low-latency) 2. Toggle between autonomous and manual modes 3. See a simple map of the car’s planned path and any detected hazards 4. Push OTA firmware updates when new AI models are trained Hardware is already on hand (Raspberry Pi 4, camera module, ultrasonic sensors, ESC, and an ESP...

I need a turnkey Bluetooth Low Energy control system that lets my staff manage indoor electric drift bikes from an Android tablet. When a rider is ready, the attendant should be able to start or stop a bike over BLE with a single tap; if the link is lost or the preset ride time expires, the bike must shut itself down automatically via an onboard, hard-wired fail-safe timer that works even when the tablet or radio link is unavailable. A physical emergency-stop button on each bike must always override everything. Security is critical: only authorised tablets may connect, commands must be encrypted, and the bikes must default to a powerless, safe state on any fault. The system will run completely offline inside a shopping mall, so no cloud services are allowed. I operate between 11 and 20 b...

I’ve completed the physical shell for a phone case with a built-in drawer. I now need a freelancer to design and prototype the **electronics + firmware** that detects drawer activity and reliably sends events to the phone/app which I have already developed. (what I need built): * Recommend the best sensing approach to detect **drawer open/close** (magnetic reed/Hall, microswitch, optical, etc.) and design around the case constraints. * Select components and create a complete electronics design: * **Low-power microcontroller + BLE** (or comparable phone connectivity) * Sensor(s) for drawer state * Battery + charging solution (or wired power if strongly recommended) * LED indicator (subtle, optional but preferred) * Provide: * Schematic, BOM, and PCB layout (compact, manufacturable...

I have a new Segway-style scooter in development and need a seasoned embedded programmer to create the entire self-balancing (gyro/IMU) firmware that will ship on the production boards. The scooter is meant for personal transportation, so reliability, safety and a polished riding feel are non-negotiable. Above all, the control loop must react instantly to rider input—acceleration, braking, tilt corrections—without hunting or lag. I will provide hardware access for bench testing as well as real-world ride data; you will transform that into a finely tuned PID (or equivalent) solution that keeps the deck level and feels natural underfoot. Beyond the core balancing logic, I want a highly customizable interface layer: riders should be able to tweak parameters (speed limits, sensit...

Every morning my iPhone has to be woken, a six-digit PIN entered, a work app opened, credentials typed, several form fields completed and a digital signature placed. I want that entire routine removed from my hands by a small desktop robot. Core flow • Wake the phone from sleep by pressing the side button. • Physically tap the screen to enter the PIN code—no Bluetooth, Face ID or Touch ID, just precise mechanical interaction. • Launch the target app, wait for it to load, populate the login screen and navigate onward until the signature page is reached and signed. I imagine a compact gantry or articulated arm driven by servos or steppers, guided by a microcontroller (Arduino, Raspberry Pi, or similar). Because the touch targets are fixed, a predefined set of c...

I need help connecting all my smart devices to a Raspberry Pi using Homebridge, and integrating them with Apple HomeKit. Requirements: - Connect lights, thermostats, security cameras, and any other smart devices. - Ensure compatibility with iOS devices. - Setup should allow control via Apple Home app. Ideal Skills & Experience: - Experience with Raspberry Pi and Homebridge. - Familiarity with Apple HomeKit and iOS integration. - Knowledge of various smart home devices and their configurations.

I need a clean, reusable .NET MAUI framework that runs on both Android and iOS. The core of the job is a Bluetooth Low Energy driver focused on monitoring-and-notification use cases, wrapped in a virtual communication layer that speaks a fully custom protocol next to standard BLE read/write/notifications characteristics Here is what I expect: - Knowledge AND EXPERIENCE how to run/build BLE MAUI applications, please add this in your response, might need communication • A solution skeleton in MAUI with well-structured projects for shared code, platform specifics, and tests. • A BLE service that discovers, connects, subscribes, and streams characteristic changes, exposing them through events/observables suitable for reactive UI updates. • The virtual channel: encode/dec...
