About the role:
Investigate and diagnose issues related to unstable Bluetooth Low Energy (BLE) connections on Windows-based computers, with a focus on:
-connection drops
- instability with multiple concurrent BLE connections
- -GATT notification latency and packet loss
The role requires an in-depth analysis of the Windows BLE stack, including:
-Bluetooth drivers (driver/firmware level)
-WinRT BLE API
- interaction between applications and the system Bluetooth stack
Bluetooth Driver Analysis:
-analyze BLE drivers provided by nRF Nordic chipset vendors
-investigate controller firmware limitations
-analyze HCI-level behavior (USB / PCIe transport)
WinRT BLE API Analysis:
-analyze usage of: Windows.Devices.Bluetooth, Windows.Devices.Bluetooth.GenericAttributeProfile
-identify issues caused by: asynchronous WinRT execution model, serialization of GATT operations, API limitations (lack of control over BLE connection parameters), provide architectural recommendations for application-side changes
Debugging and Diagnostics:
-analyze Windows system logs: Event Viewer, Bluetooth ETW traces,
-use diagnostic tools such as: Bluetooth LE Explorer, Windows Performance Recorder / Analyzer, correlate application-level events with driver and stack behavior
Windows
-solid understanding of: Windows Bluetooth stack architecture, differences between Win32 and WinRT,
-practical experience with: WinRT BLE APIs, BLE integration in desktop
