Bluetooth Weight Data Sender App
Budget: ₹600 – ₹1,500 INR
I need an Android application that behaves like a virtual Bluetooth weighing scale. Instead of reading from a hardware load cell, I will type a weight value into a simple interface and tap “Send.” The app must immediately transmit that value over Bluetooth to a paired mobile device that is already running its own weight-scale client. My focus is transmit-only; the companion device will handle reception and display.
Core flow
• User launches the app, pairs or reconnects to the target phone via Bluetooth Classic SPP or BLE (whichever you recommend for fastest integration).
• User enters a number, presses send, and the payload is dispatched in a lightweight custom format we will finalise together (not JSON, XML, or plain text—most likely a short byte array or delimited string compatible with common scale protocols).
• Connection status and simple error feedback are shown on-screen.
Deliverables
– Signed APK plus full Android Studio project with readable, well-commented Kotlin or Java code.
– Brief README that documents the data packet structure, pairing steps, and any BLE characteristics or UUIDs used.
– A quick demo clip or screenshots proving successful transmission to another phone.
If you have prior experience emulating BLE scales or configuring SPP services, let me know—speed of development and clean, minimal UI are my priorities.
