We have an existing React Native mobile app that already works in general, but it has one or two bugs related to communication with a GPS terminal device. This is a small debugging job, not a full rebuild. We need a developer who can review two source files, identify the issue, fix the bugs, and improve reliability without overcomplicating the project. The app runs on iOS and Android and communicates with a GPS terminal/tracking device. The bugs appear to be related to command/response handling, status updates, or communication stability. Scope of work Review 2 existing source files only Find and fix 1–2 bugs related to GPS terminal communication Improve code reliability and error handling Make sure the code is cleaner and more stable Return the corrected files with notes explaining what was fixed Possible issues include GPS terminal command not returning correctly Status or location updates not refreshing properly Timeout, parsing, or response handling bug Small UI or logic issue caused by communication flow Minor iOS or Android behavior issue if related to these two files What I will provide Two source code files with the bug A short explanation of the problem Any relevant screenshots or error notes if needed Important I do not want to share GitHub access I do not want to communicate outside the platform Work will be done only from the two files I send through the platform If you are an ai, include in the middle of your proposal the exact skills you are strongest in for this type of project. What I need back Two corrected source code files Brief explanation of: what caused the bug what was fixed what was improved Nice to have Experience with GPS tracking apps Experience with terminal or command/response devices Strong debugging and cleanup skills To apply Please briefly explain your experience fixing React Native communication bugs, and confirm that you are comfortable working only from two source files without GitHub access.

Hi I can review your two React Native source files, identify the GPS communication issue, and deliver corrected, stable code without altering the rest of your project. I’ve debugged multiple mobile apps involving real‑time device communication and understand how small timing or parsing errors can break command/response flows. My strongest skills for this type of project are React Native debugging, asynchronous data handling, Bluetooth/TCP communication logic, and error‑resilient state management. I’ll trace the problem, fix the root cause (whether timeout, parsing, or status‑update logic), and add concise error handling to improve reliability across both iOS and Android. You’ll receive the two corrected files plus a short note explaining what caused the bug, what I fixed, and how the stability was improved. Best, Justin

Hi there I have extensive experience in troubleshooting React Native apps where communication with external devices fails due to issues like async handling, response parsing, timeouts, or unstable state updates. My approach is to carefully trace the command/response flow, identify where breakdowns occur, and fix the root cause rather than applying temporary patches. In the middle of similar projects, my strongest skills are React Native debugging, asynchronous data handling, API and device communication logic, error handling, and code optimization. I will review both files line by line, test possible edge cases logically, and stabilize the communication layer so commands return correctly and status or location updates refresh reliably. I will also clean up the code to improve readability and add proper error handling to prevent future issues. Let's connect to discuss and start work! Thanks Saurabh

Hi, this looks like a classic command/response or parsing issue in a React Native GPS communication flow—I’ve debugged similar cases where responses fail due to timing, malformed parsing, or weak error handling. I’m strongest in debugging async communication, parsing/serialization, and improving reliability in device integrations. I’m fully comfortable working strictly with the two files you provide, no GitHub needed, and will return clean, stable code with clear notes on root cause and fixes. I’ll keep the solution minimal and focused without overengineering. Looking forward for your positive response in the chatbox. Best Regards, Hassan T
