Salut, Am vazut profilul vostru si cred ca v-ati potrivi pentru proiectul meu. Am nevoie de un dispozitiv care sa permita trimiterea de imagini (jpg si gif) pe un display epaper prin bluetooth. Display-ul este acesta (de la un kindle 3) El mai are nevoie de un controller inainte de a fi conectat la un microcontroller (cred ca un Arduino Due ar fi ideal). Alimentarea va trebui sa fie pe baza unei baterii. Cablul dintre display si controller va trebui sa fie putin prelungit (sa aibe undeva la 40cm ) Sa-mi spuneti daca v-ar intresa acest proiect. O zi placuta, Cristi

...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 • Design the main PCB around a low-power processor that can r...

I need a custom-built Android application that lets me override every major device identifier for privacy testing purposes. The app must spoof the IMEI (confirmed by *#06#), serial number, all MAC addresses (Wi-Fi, Bluetooth, Ethernet), IP and port data, GPS location, and the Google Play Store email ID. Once a value is changed it has to survive reboots and appear system-wide—Settings, third-party apps, and any common USSD or diagnostic code must all report the spoofed data, not the genuine one. Because I want to use this on any handset or tablet, it should run across all Android versions and models. If root, Magisk modules, Xposed, or similar low-level methods are required, build those steps into the solution and document them clearly. A simple UI where I can enter custom val...

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

I already have a fully textured 3ds Max model plus short demo videos ...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 Bluetooth packet within one second. • Final delivery includes full...

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 ...

...lights turn on automatically. If we additionally activate the right turn signal indicator, the right auxiliary light will turn off so that the turn signal has more prominence and oncoming drivers can better identify the action the motorcycle is about to make. Elements to Use: This is the part where I hope you can help me. We will use an ESP32 microcontroller. I would like it to have WiFi and Bluetooth, with a good amount of memory since it will have a web server running (for configuring the lights as the client needs) The system will have 6 output lines (15A lights, charging USB, rear light, etc.) Each line will be controlled by D4184 MOSFETs in parallel. It's important that the MOSFETs can operate with PWM so we can dim the lights as needed For every 2 channels we will ha...

I’m ready to move from concept to code on a new Bluetooth-enabled mobile application and need an experienced developer who can take the reins from architecture through store-ready builds. The core idea is simple: the app must discover nearby devices, establish a reliable connection, and exchange data quickly and securely. I’ll share the exact use-case and device specs once we start; for now, assume the usual Bluetooth Low Energy workflows—scan, pair, read/write characteristics, and handle reconnections gracefully. Because my audience uses both iOS and Android phones, I’m leaning toward a single codebase (Flutter or React Native) but I’m open to native if you feel that’s wiser for latency or background-mode restrictions. Whichever route you...

I’m ready to turn a clear functional outline into a polished FlutterFlow application. The core of the job is enabling simultaneous Bluetooth LE connections to both a cadence sensor and a heart-rate sensor, then streaming that data live to the trainee’s phone. Once connected, the app must keep the rider engaged by showing real-time pedaling cadence (RPM), current speed, and a continuous estimate of calories burned. Above those numbers sits a coloured effort bar that fades from gray through yellow to deep red so anyone can see instantly how hard they are working. When a session ends, the rider should land on a neat workout-summary screen and be able to review every previous ride in a daily history view. I would like this data saved to the cloud so history is retained eve...

The goal is to create a straightforward Android application that pairs with my ESP32-based smart bait boat over both WiFi and Bluetooth. From a single screen I want to steer the boat with an on–screen joystick, trigger preset bait-container positions (Half Open, Fully Open, etc.), adjust speed and other numeric parameters, and view a small live GPS mini-map. I will supply the ESP32 firmware protocol; your task is the Android side. Please build the project in Android Studio (Kotlin or Java is fine) and keep your code modular so I can extend it later. ESP-Now, classic Bluetooth, or BLE can be used under the hood as long as the boat can be discovered, paired, and commanded reliably. Deliverables • Compiled APK demonstrating all features with my test boat • ...

I need our existing Android app to talk smoothly to a Bluetooth thermal printer and, while you are in the code, refresh the look of one key report. Integration first: the app must discover, pair with, and print to a standard 58 mm or 80 mm Bluetooth unit. I’m open to the usual brands—Epson, Zebra, Brother—as long as the final APK prints reliably and reconnects automatically after the first pairing. Raw ESC/POS commands or an official SDK are both fine; pick whichever gives the fastest, most stable print. Report revamp next: the data is already there, but the current layout is cramped and hard to read once printed. I want cleaner spacing, clearer section headings, and a hierarchy that looks good on both the in-app preview and the physical slip. No new ca...

Project goal, to create a Bluetooth transmitter that pairs with the insta360 x5 camera and transmits line-in audio via Bluetooth to the camera. I need an experienced Bluetooth-Classic analyst who can hook up an Ellisys BR/EDR sniffer to my setup and hand me clean captures of everything that happens between an Insta360 X5 camera and its Mic Air wireless microphone. Here is where I am right now • I have proved that the camera pairs over BT-Classic, not BLE. • Using an ESP32-A1S I can reproduce the pairing, yet 3 seconds after I start recording, I get an audio anomaly and the entire recording stops. There is no audio saved in that time. What I must understand • Full packet-level flow for both the initial pairing and the ongoing A2DP + HFP/HSP s...
