As an experienced Android application developer, I possess the essential skills for your project and align well with what you seek. Over my 10+ years in this field, I've developed scalable and secure mobile applications, using languages like Flutter and React Native. In conjunction with this profusely strong skill set is my ability to work with low-level serial communication which fits exactly to the needs of your Bluetooth RFID system. When we talk about extracting numerical data from complex systems without any SDK, reverse engineering becomes critical. As part of my career, I have proficiently delved into projects that required me to 'discover' protocols for hardware that shipped without libraries, akin to your requirements. This has allowed me to maximize my sniffing capacities thus enabling me to successfully interpret data streams. My commitment to delivering reliable performance leads not only toward deploying real-time information swiftly but storing those databases and allowing for easy exportability (which you mentioned you need). My dedication and extensive experience assure timely delivery while maintaining clear communication throughout the process. I genuinely believe together we can ensure seamless integration of your RFID reader with your dedicated Android app in a remarkably effective timeline.

​Hi, ​I read your project description carefully, and I have strong experience in Bluetooth protocol reverse engineering, low-level serial communication, and custom Android app development. ​Since your RFID reader lacks an official SDK, here is how I plan to approach and tackle this project: ​Protocol Sniffing & Analysis: I will use tools like Wireshark, nRF Connect, or custom sniffing scripts to capture and analyze the raw Bluetooth data packets transmitted by the RFID reader when a tag is scanned. ​Frame Decoding: Once the raw data stream is captured, I will reverse-engineer the packet structure to isolate and extract the exact numeric payload of the RFID tags. ​Custom Android App Development: I will build a dedicated, clean Android application that connects via Bluetooth, listens to the decoded data stream in real-time, displays the scanned tags in a simple list view, and includes a local export feature (TXT/CSV). ​Testing & Validation: Using the live access and sample tags you provide, I will thoroughly test the connection to ensure that powering up the reader, opening the app, viewing codes instantly, and exporting logs works seamlessly. ​Timeline: I can complete this workflow and deliver the fully functional app within [insert number, e.g., 5-7] days once I have access to the device and samples. ​Let's discuss this further so we can get started right away! ​Best regards, Muhammad Umair

I can reverse-engineer the RFID reader’s Bluetooth communication, analyze raw packets, identify tag data formats, and build a reliable Android app around the discovered protocol. I’ll capture and decode the Bluetooth traffic, determine how numeric tag data is transmitted, then implement the communication layer and integrate it into a clean, purpose-built Android application. I can also handle testing and device compatibility. Contact: +91 88264-50850

Hi, I’d be happy to build the Android companion app for your RFID reader and work through the Bluetooth protocol discovery. Since there’s no manufacturer SDK, I can analyze the reader’s Bluetooth communication, identify the packet structure, decode the relevant tag payload, and integrate that logic into a clean Android application. The app can handle device connection, real-time tag reading, numeric payload extraction, local session storage, and CSV/text export. I’ll test the implementation against your physical reader and sample tags to ensure readings are captured consistently and displayed without noticeable delay. I’ll keep the Bluetooth/protocol layer modular so it can be maintained or extended later, and provide the complete Android Studio project with clear documentation. Once you provide access to the reader and sample tags, I can begin protocol analysis and establish the development timeline. Best regards, Umar

Hi, I can help you with this RFID and Android project. I have experience in Android development and working with Bluetooth communication, so I can analyze the raw Bluetooth packets from your RFID reader even if there is no SDK available from the manufacturer. I can first understand how the reader communicates with the Android device, capture and analyze the packets, identify the RFID tag data and find how the numeric value is stored in the response. After that, I can develop a new Android app which connects directly to the reader through Bluetooth and reads the required tag information. I understand that reverse engineering the communication protocol can require some testing and packet analysis, so I can work step by step and make sure the extracted data is correct before building the final app. I am ready to start and would be happy to discuss the RFID reader model and available hardware details.

I can help you create an Android app that communicates seamlessly with your RFID reader over Bluetooth. The goal is to see those tag numbers appear on-screen in real-time, making the process efficient and user-friendly. I noticed you mentioned the need for protocol discovery and real-time data display. My approach would involve a systematic exploration of the Bluetooth packets to decode the frames and pull the numeric payload. With the device in hand, I’d test and iterate to ensure consistent performance. I have done similar work: "Modern Real Estate Investment Website" - [Link]. This project required precision in displaying data, which is essential for your app as well. Let’s chat about your project further. You’ll get a free consultation, and we can discuss the best approach to make this a success. Regards, Dean

Hi, this is a great fit - I've been building production Android apps for 10+ years, and I currently work on Hungary's national digital identity platform, which involves this exact kind of low-level hardware integration (NFC, MRZ scanning, biometric auth with no vendor SDK). My approach: 1. Protocol discovery: capture raw traffic first - btsnoop log + Wireshark for classic SPP, or nRF Connect to enumerate GATT services/characteristics if it's BLE. 2. Frame analysis: using your sample tags, diff the raw byte sequences to isolate the fixed frame structure vs. variable tag payload, and confirm any checksum/terminator pattern. 3. Android app: build on BluetoothAdapter/BluetoothSocket or BLE GATT callbacks (depending on step 1) - background thread decoding each frame, real-time list view of tag numbers, local storage with CSV/text export. Quick question: is the reader Bluetooth Classic (SPP) or BLE? That determines my sniffing approach. Estimated timeline: 3-4 days from receiving the device, sharing the btsnoop capture and frame-format notes as I go so you can track progress.
