Upgrade My Android BLE App -- 2

@om26er

I have been working in Android Studio fore more than 10 years now because I use it for native app development. I can surely update your BLE app and make sure it works flawlessly with your new hardware. I am a full stack developer so I can modify the API as well so it doesn't keep deleting the data. I have done more than 525 projects on this platform with 99% project completion rate. Let's chat and get started.

Swapping a BLE app to new hardware is mostly a GATT layer job, so I'd start by isolating the current service/characteristic constants into a single profile class, then map your new UUID list onto it — service, control characteristic, notify/indicate characteristic. From there I'd rework scanning and pairing with BluetoothLeScanner filters, request MTU, and queue every read/write/descriptor operation so notifications for real-time sync don't collide with control commands (start/stop and parameter changes). Reconnect and bonding are handled so the phone recovers if the board drops. On the API side, data disappearing after a few days usually means a TTL/cleanup job, a cache being treated as storage, or upserts overwriting rows by key. I'll trace the write path and retention logic, fix the root cause, and add a sync log so nothing is silently lost. Delivery is the updated Android Studio project, a signed APK, and a change log with tests run on two OS versions (I'll use Android 12 and 14 unless you prefer others). Do you have the new board with you for testing, or should I validate against your test procedures only? Muhammad Saad

Hi, I reviewed your request to upgrade the existing Android BLE app so it can discover, pair, and communicate with new hardware using the provided UUID map. I’ll update the Android Studio codebase to integrate the new GATT profile, confirm stable read/write operations, and wire real-time data synchronization between the phone and the BLE board. I’ll also ensure device-side control functions (start/stop and parameter changes) remain fully supported, while keeping API integration reliable despite the recurring data deletion by adding proper synchronization and persistence safeguards. I’ll deliver the updated source project, an installable APK, and a brief validated change log for at least two Android OS versions. Let’s discuss here now.

Hello!! Your existing Android application can be upgraded for the new Bluetooth Low Energy board with stable GATT communication, real-time synchronization, device controls, and reliable API data storage. * Do you already have the new BLE UUID map and test procedures ready? * Which Android versions should be prioritized for testing? * How long should API data remain stored without deletion? The existing Android Studio codebase will be carefully updated without disrupting current functionality. BLE discovery, pairing, read and write operations, real-time data flow, and start/stop controls will be tested thoroughly. The API will also be reviewed to identify why data is being deleted and corrected with reliable storage handling. Relevant Android, BLE, API integration, and device communication projects have been completed, with strong attention to stable real-time data exchange. Let us discuss the existing code and hardware details in chat. Best regards Farhin B

Hi, I can update your existing Android Studio project for the new BLE hardware and also investigate the API issue causing stored data to disappear after several days. I’ll first map the supplied UUID/GATT specification against the existing BLE layer, then update discovery, connection, characteristic read/write, notifications and device-control commands. I’ll make sure real-time synchronization handles reconnects, connection loss and state changes cleanly rather than only working during an ideal test. On the API side, I’ll trace the full data lifecycle including Android requests, API endpoints, database writes/updates, scheduled jobs and any retention/cleanup logic to identify why records are being deleted. Deliverables include the updated Android source, APK, API fixes, testing across at least two Android versions and a concise changelog.

Project Details $30.00 – 250.00 USD Bidding ends in 9 hours, 51 minutes I have an existing Android application that already works with an earlier Bluetooth Low Energy device. I am now moving to new hardware and need the app updated so it can discover, pair with, and communicate seamlessly with this new BLE board. Your main objectives are: • Integrate the new GATT profile and confirm stable read/write operations. • Enable real-time data synchronization between the phone and the device. • Maintain full device-side control functions (start/stop actions, parameter changes, etc.). Please work in Android Studio; the current codebase is structured for that environment and all future maintenance will stay there. I will supply the existing project, the new device’s UUID map, and test procedures. Final deliverables are the updated source project, an installable APK, and a brief change log confirming that data sync and control commands have been validated on at least two Android OS versions. Also, it's updates that need to be done on the API side as well, as the API KEEPS DELETING DATA A FEW DAYS.

Hi there, I think you want to upgrade the existing Android BLE app to the new GATT profile while keeping all current device controls reliable, and also fix the API issue that is deleting stored data after a few days. I can work directly in Android Studio, update the BLE discovery/pairing, implement stable GATT read/write and real-time synchronization, and preserve start/stop and parameter controls. On the backend, I’ll trace the API, database, scheduled jobs, retention logic and sync flow to identify why records are being deleted, then implement a safe fix and validate data persistence. I’ll test BLE communication and API behaviour across at least two Android versions and deliver the updated source, APK and concise change log. Thanks,

@Proswift

Hi, You’re updating an existing Android BLE app for new hardware: discover/pair, new GATT profile, stable read/write, real-time sync, and full device control (start/stop, parameters). Also need API-side fixes so data stops disappearing after a few days. I specialize in Android + BLE (Kotlin/Java) — GATT services/characteristics, notifications, and reliable control loops with hardware. I’ll integrate your new UUID map in Android Studio, keep the current structure, and validate sync + commands on at least two Android versions. For the API data loss: I’ll check retention, delete jobs, TTL, and write paths so records persist unless you intentionally purge them. Price: $100 Deliverables: updated project, APK, short change log. Best regards

@shawanay

I’m an experienced Android developer skilled in Android Studio, Kotlin/Java, BLE, APIs, and real time data sync. I'll do * Integrate the new BLE GATT profile and stable read/write communication. * Maintain device controls and real time synchronization. * Fix the API data deletion/persistence issue. Q: Do you already have the BLE UUID map and API code ready to share? I can start immediately. Regards

@ssquare489

For this update, I’d treat the BLE migration and the API data-loss issue as two connected reliability problems: the Android app must communicate cleanly with the new GATT profile, while the backend must persist synchronized device data without unexpected deletion. I’ll work directly in your existing Android Studio codebase, update discovery/pairing for the new UUID map, implement characteristic read/write and notification handling, validate start/stop and parameter commands, and harden reconnect/state-management logic for real-time synchronization. My two priorities would be integrations and maintainability, so future BLE hardware revisions can be supported without rewriting the communication layer. On the API side, I’d trace why records disappear after several days by reviewing database retention/TTL settings, scheduled cleanup jobs, cron tasks, cascade deletes, synchronization logic, and any API-side overwrite behavior. Fixing the underlying persistence issue will prevent historical device data from silently disappearing. A relevant example is FileChannels, where we built mobile and real-time functionality involving continuous state synchronization, notifications, APIs, authentication, and production data flows. Deliverables will include the updated Android Studio project, APK, API fixes, change log, and validation across at least two Android OS versions using your supplied test procedures.
