Bluetooth Jobs

I’m putting together a dedicated, distraction-free reading device and need a hardware specialist who can take it from concept to working prototype. The display has to be an AMOLED panel of at least 11 inches—no compromises on that vibrant contrast. This will be a reading-only tablet, so efficiency, eye comfort, and battery life have priority over raw processing power. Wireless connectivity is essential for loading books and updates; Wi-Fi is mandatory, Bluetooth is optional. In addition, I want physical page-turn buttons on the bezel so users can flip pages without touching the screen. Touch input itself is welcome but not a requirement. Here’s what I’m expecting from you: • Source and validate the 11″+ AMOLED display and its driver board • Desi...

A NRF52 based low power consumption BLE tag with 4G and GPS capabilities. Features: Microcontroller: NRF52, any GPS + 4G module operable in south america Power Supply: Lithium-ion Battery (600mAh+, auto-switching) Communication: Bluetooth + GPS + 4G Additional Components: RGB LED and Buzzer Reprogramming Method: SWD The board must consume the absolute minimum power (~10uA) until GPS + 4G is enabled via software.

I already have the hardware in hand (see the exact unit here: ) and need it configured into a rock-solid link for a DJI Matrice 400. The goals are simple but non-negotiable: • The device must pair over Bluetooth with smartphones and tablets, then feed telemetry and video to the Matrice in real time. • The whole chain has to stay online even when nearby frequency jammers or other RF noise are present. • Live status dashboards and alerts are required so I can see, at a glance, that every hop in the link is healthy. Here’s how I picture the collaboration: 1. You review the hardware specs and choose the most resilient protocol settings (frequency-hopping, spread-spectrum, encryption, power levels, antenna layout, etc.). 2. You walk me through the exact configurati...

I already have a fully textured 3ds Max model plus short demo videos that show the exact interaction I need. Your job is to wrap this model in a lightweight mobile viewer that runs on Android. The user must be able to pinch-to-zoom, orbit, and pan the model smoothly; two on-screen buttons will also zoom the camera and simultaneously transmit predefined Bluetooth 5.0 packets to my external hardware. I can deliver the .max file along with the precise hex strings for the Bluetooth commands. The build should render cleanly on mid-range phones and pair reliably with any Bluetooth device. Acceptance: • The app installs and runs on one Android device. • Touch gestures perform as shown in the videos. • Pressing either button updates the camera view and sends the correct Blu...

I need a complete mixed-signal design for an eight-channel Bluetooth communication system: four inputs for data acquisition and four outputs for actuation or stimulation. The unit must span a wide frequency range—everything from standard audio bandwidth up into the low-MHz region—while keeping each output capped at 5 V, 5 mA so it remains safe for direct human-facing applications. Because the project will handle live data, the entire chain has to support real-time streaming over Bluetooth Classic; latency has to stay low enough that an audio-rate round-trip remains perceptually seamless. Inside the enclosure, you can split the path however you wish—purely analog front ends feeding ADCs, DSP blocks, then DACs and analog output buffers—so long as the final architec...

I want a lightweight Android app that lets me create bills completely offline. The flow is straightforward: with a stylus I jot down the item name, quantity and rate, the app recognises my handwriting, drops each line into a table, and lets me add a rupee-value discount before totalling up. At the press of a button the bill prints to a Bluetooth thermal printer in a simple, clean layout—just the item list and the grand total. No shop name, GST or other headers. The same bill should also be saved locally as a PDF and be shareable instantly through WhatsApp. Every bill needs to be stored in an on-device history that I can browse inside the app or export later as CSV/PDF for wider reports. All features must stay fully functional without an internet connection. Deliverables &bul...

I need a clean, production-ready PlatformIO project for the Nordic nRF51822 written in C/C++. The example must boot, scan for nearby BLE devices, connect to one of them, and exchange plain text strings—ideally via a Nordic UART–style GATT service. Please build it around a SoftDevice or Nordic SDK you have already proven on real hardware; I do not want AI-generated scaffolding that compiles but fails at runtime. The code should: • compile inside PlatformIO with a single pio run command • flash successfully to an nRF51822 DK or compatible module • start scanning, connect on the first match, and perform a two-way text message exchange • cleanly disconnect and resume scanning Deliverables I’ll review: 1. A complete PlatformIO project folder (ma...
