With a strong background in Bluetooth Low Energy (BLE) development, I understand the intricacies of troubleshooting connectivity issues. I recently resolved a similar bug in a mobile app that disrupted BLE communication. Could you share more details on the SSH connection that triggers the issue? Regards, Yogesh Kumar

Hello, Your POC sounds very close, and the failure mode is clear: BLE works for minutes, then the Android connection state changes and the link to Windows dies. That’s exactly the kind of Android / Mobile Development issue I like to debug, especially when the final fix must stay within the stock Android BLE API. I’d trace the disconnect path end-to-end in Android Studio with targeted logging, verify whether the app is reacting to a GATT callback, transport timeout, or an unrelated SSH-side state change, and then isolate the exact condition that breaks forwarding. Once reproduced, I’ll patch the source, comment the change clearly, and return a clean pull request or zipped module with a short root-cause summary. I’ve worked on Android-facing device communication and low-level C Programming style fixes where stability and event handling matter more than UI. For this one, my focus would be on keeping the BLE session alive, preventing false disconnect handling, and making the reconnect/stream logic resilient. Osama

❀༺ Hope you’re having a good day ༻❀ Your project is quite similar to Android BLE debugging and connection-stability issues I’ve worked on before, and it aligns well with my experience. I appreciate the opportunity. As a mobile developer with over 8 years of experience in Android, Bluetooth Low Energy (BLE), and device communication, I have diagnosed and resolved many connection-drop issues involving Android devices, Windows clients, HID-style communication, and background networking conflicts. From your description, the fact that communication works for several minutes before failing suggests a state transition, connection parameter update, bonding issue, service conflict, or interaction with another transport layer such as SSH rather than a basic BLE implementation problem. My approach will be to instrument the connection lifecycle with detailed logging, reproduce the failure, analyze GATT state changes, connection intervals, MTU updates, and any interactions between BLE and SSH/network components. I will use Android Studio, nRF Connect, and protocol-level debugging to isolate the root cause and implement a clean fix using only the stock Android BLE APIs. You will receive fully documented source updates, a clear explanation of the root cause, and a reliable solution that preserves stable communication between Android and Windows during extended sessions. Best regards, Jayant

Hello! I can help fix that BLE disconnect bug you're seeing. The issue where the phone loses connection to your Windows app after some time—especially when it seems related to an SSH connection—sounds like a classic timing or resource conflict. When you get that connection state change, the phone might be trying to disconnect while the app still thinks it's connected, or the system might be holding onto the Bluetooth GATT object improperly. Recently, I fixed a similar issue for a client who was connecting an Android app to a custom BLE device. The connection would drop randomly after a few minutes. I found the problem was a race condition in the disconnect logic. By adding a small delay (around 500ms) after the `onConnectionStateChange` callback before trying any reconnection attempts, the app could properly handle the state change without causing a conflict. For your specific issue, where SSH seems to be involved, I suspect the BLE connection might be interfering with the SSH connection's use of the same network resource. The fix could involve making sure the app properly closes the GATT connection when it detects the state change, and ensuring the disconnect call is handled correctly. My approach would be to add detailed logging to track the exact sequence of events, ensure the disconnect logic properly handles the callback, implement a small delay before attempting reconnection, and make sure the GATT client is properly closed when the connection is lost.

@adisonw

Dear Sir, I am thrilled to bid your project. I can help debug and fix the Android BLE communication issue where the Xbox controller input forwarding works initially, but the BLE connection later changes state and communication with Windows stops. Since the POC is already mostly working, I would focus specifically on reproducing the disconnect/state-change behavior, adding targeted logs around BLE callbacks, GATT connection state, MTU/notification writes, threading, and any SSH-related trigger that may be interfering with the connection lifecycle. My approach would stay within the stock Android BLE API as requested. I can use Android Studio logs/profiler, nRF Connect comparison testing, and controlled connection tests to identify whether the root cause is callback handling, service discovery reset, write queue failure, connection priority, permissions, or lifecycle/background behavior. Deliverables would include a clean PR or zipped module, clearly commented fix, and a short explanation of the root cause and changed code. One question: is the Android app using BLE GATT server mode, GATT client mode, or both when communicating with Windows? Sincerely, Adison

@chazcarey

Hi, I will debug and fix the BLE disconnect issue in your Android application while keeping the existing Xbox controller forwarding workflow intact. I have worked on Android BLE projects involving GATT connections, characteristic notifications, reconnect handling, MTU negotiation, background services, and Windows communication. I will trace the exact connection-state transition causing communication loss and identify whether it originates from Android BLE lifecycle handling, GATT callbacks, write queue management, service discovery, or interaction with the SSH/network layer. My process: ✅ Review BLE connection flow and logs ✅ Add targeted debugging around BluetoothGatt callbacks ✅ Reproduce the disconnect consistently ✅ Identify the root cause instead of applying temporary patches ✅ Implement and test a stable fix ✅ Verify long-duration communication with Windows ✅ Deliver clean, documented source changes Deliverables: • Updated source code (PR or ZIP) • Clearly commented fix • Root-cause analysis • Brief documentation explaining the changes I have fixed similar BLE stability and disconnect issues before and can start investigating immediately. Regards, Chaz C.

@carlosd178

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience handling similar Android BLE debugging and mobile-to-Windows communication issues and I'm available to start your project right now. I bring deep expertise in Android, Android SDK, Android Studio, Bluetooth Low Energy, Debugging, Mobile App Development, C#, C Programming, and mobile development with over 10 years of experience. One of the key challenges here is identifying why the BLE connection state changes after successful communication, especially if it appears related to SSH or another background connection conflict. I can add targeted logging around GATT callbacks, connection state changes, MTU/notification handling, bonding, reconnect logic, and Windows-side communication timing to isolate the root cause. A simple solution would be to reproduce the issue, inspect Android BLE logs and Windows connection behavior, confirm whether the disconnect is caused by lifecycle/threading, GATT callback handling, permissions, or competing network/SSH logic, then provide a clean fix within the stock Android BLE API. I have a quick question. • Is the Android side written in Kotlin/Java, or is there also native C/C++ involved in the BLE module? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos

@sihalaths9

Hello, I’m glad to have found your project, it aligns perfectly with my skills and professional interests. I’m excited to help stabilize your Android BLE connection between the phone and Windows so your Xbox controller bridge stays reliable. I understand the issue appears after a stable GATT session, where a later connection-state change breaks communication despite successful initial pairing and data transfer. With strong experience in Android SDK, Bluetooth Low Energy, C#, and device-to-device communication, I’ve handled similar BLE instability cases caused by GATT lifecycle issues, service conflicts, and improper reconnection handling. I would focus on reviewing your BluetoothGattCallback flow, connection parameters, threading model, and any background services or network events that might indirectly trigger disconnects. I rely on structured logging, nRF Connect, and Android Studio profiling to reproduce and isolate timing-based failures. The aim is to fix the root cause so the connection remains stable over long sessions. I’d like to go over a few points: Does the failure correlate with app backgrounding, screen lock, or network changes like WiFi/VPN/SSH activity? Is your BLE service running in a foreground service with explicit reconnection handling? I’m confident I can make this project a success. Thank you for considering my proposal, and I hope we can collaborate soon.

@edwarddzi8f

Hi there, I can help you with tracking down that BLE disconnect bug. The pattern you're describing, where it drops after a few minutes of successful communication and seems tied to an SSH connection, makes me think it could be a GATT service discovery timing issue or a bonding problem that gets triggered when the network stack changes state. I'd start by adding detailed logging around the onConnectionStateChange callback and checking if the disconnect correlates with any MTU negotiation or service discovery events. I'm Edward and I've debugged similar BLE stability issues before. Happy to chat about this.

@devitmd98

I understand you have a working proof of concept where an Xbox controller connected to a phone is successfully forwarding inputs over Bluetooth Low Energy to Windows, but after some time the Android to Windows communication stops when a connection state change occurs that seems related to an SSH session. I have experience debugging stability issues in Android BLE communication using the native Android BLE stack and diagnosing intermittent disconnections caused by lifecycle management, background restrictions, and conflicting network or tunneling services. My approach would be to instrument the BLE connection lifecycle in Android, focusing on GATT state transitions, reconnection handling, and ensuring the service remains in a stable foreground state so it is not affected by system optimization or background limits. I would also inspect whether the SSH connection is introducing routing changes, socket conflicts, or triggering system level network changes that indirectly affect the BLE service stability. The goal would be to stabilize continuous BLE communication, add robust reconnection logic, and eliminate any external service interference so the controller input stream remains uninterrupted. I will provide a clean source update with clearly commented changes and a short explanation of the root cause and fix.
