You will get a fix for BLE / Bluetooth Connection Issues in Mobile Apps
Top Rated
Project details
Bluetooth and BLE issues can be some of the most difficult problems to diagnose in mobile applications — especially around background behaviour, reconnection logic and long-duration stability.
I specialise in investigating and stabilising BLE-connected iOS, Android and React Native applications, including CoreBluetooth issues, Android BLE instability, background disconnects and unreliable device communication.
I have worked on connected products and BLE systems for companies including Bose, Corsair, RHA, Musclegun, Phlex Swim, ZIIP Beauty, Oxiline and Neutrally, covering consumer audio, wearables, health devices and connected fitness products.
Depending on the package selected, work may include:
• reviewing BLE architecture and connection flow
• analysing background handling
• adding targeted diagnostic logging
• long-duration stability testing
• reproducing disconnect/reconnect failures
• CoreBluetooth / Android Bluetooth investigation
• React Native BLE debugging
• identifying root causes and remediation options
• optional stabilisation recommendations and fixes
I work with native iOS, Android and React Native BLE implementations.

30 minute consultation
I recently booked a consultation with Samuel, during the 30mins session we covered all the desired topics from my side and I gained a greater appreciation of the BLE Bluetooth landscape and the complexities involved. Highly recommended.

I’m often brought into projects that are close to release or experiencing issues, to assess build quality, resolve problems, and ensure successful App Store / Play Store submission.
This includes stepping into existing React Native apps to:
* fix bugs and stability issues
* upgrade React Native versions
* resolve build and deployment problems
* improve performance and reliability
I am an Upwork Top Rated Plus developer based in the UK, with extensive experience across iOS (Swift, SwiftUI, Objective-C) and React Native.
My core areas of expertise include:
* Bluetooth Low Energy (BLE) and connected device integration (health, fitness, audio)
* React Native development, debugging and stabilisation of existing apps
* iOS development (iPhone, iPad, Apple Watch, Apple TV)
* App review and pre-submission optimisation
* End-to-end system design (device ↔ mobile ↔ backend)
I have worked with global brands including Bose, Corsair, Musclegun, SC Johnson and others, delivering production applications across consumer, health and wellness sectors.
My focus is always on delivering reliable, production-ready applications that perform consistently in real-world use.
I’m comfortable working with both startups and established teams, and can quickly step into existing projects to provide clear direction and deliver results.
