Key points the finished solution must cover: • Seamless Bluetooth or USB communication with the TVS thermal printer (other brands in future should be easy to add). • Fast barcode generation and a landing page that displays the stored bill on mobile browsers. • Clean, minimal entry form with <12 inputs and our logo positioned correctly on the printout. • Source code, build files, and basic setup documentation s...

I’m building a single, integrated application that lets my garment stores handle sales, stock and bar-codes without hopping between tools. At its heart is a full Billing module: I need a drag-and-drop invoice designer where I can drop in our logo, brand colours and choose which fields go where. During checkout the cashier should be able to scan a barcode—USB gun, Bluetooth scanner or even the mobile camera—and watch the system pull the item, auto-calculate price, discounts, GST or other taxes, then accept payment by Cash, UPI or Card. Once payment posts, the app must generate an invoice automatically (manual, milestone or scheduled runs are also fine) and offer a print-ready PDF. Real-time payment status, plus overdue reminders, keep us on top of receivables. Th...

...brings reliable wireless communication to a new consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long lead times and proposing substitutes whe...

...as small and light as possible. The idea is that a bow hunter can easily track and find their game after a shot is taken. This would ideally be the most ethical form of locating an animal to ensure that it is not gone to waste. Here’s the functionality I have in mind: • The device gathers GPS coordinates, pushes them to the user’s phone over low-energy Bluetooth, and refreshes quickly enough to feel truly live. • When Bluetooth isn’t possible or range is lost, a secondary short-range radio link should take over so position updates continue (I’m open to the specific protocol you recommend). • Everything must be optimized for battery life, ruggedized for rain and mud, and small enough to be fit into a broadhead style design f...

I want to ship a lean Android + iOS application that can 1) establish a Bluetooth Low Energy link to my peripheral and move data back and forth, and 2) instantly push out a user-defined BLE packet the moment the phone detects an incoming call. The BLE work is classic data-transfer: discover the device, pair, subscribe to characteristics, then read/write packets on demand. Stability in the background is critical; the link must stay alive (or reconnect quickly) when the screen is off. When a call arrives the app should listen to the system broadcast (Android) or CallKit/VoIP push workaround (iOS), pull the string the user previously defined, and write it over the existing BLE connection without visible delay. Please send a concise, detailed project proposal outlining: &bull...

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

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 ...
