PROFILE
Haiwen Xia
Haiwen Xia developed and enhanced embedded firmware for the telink-semi/hal_telink repository, focusing on stability, power efficiency, and memory optimization for Telink B92, TL321X, and TL721X devices. He implemented features such as BLE low-power exit latency handling, 60MHz MSPI clock support, and RAM-optimized library integration, using C and YAML within the Zephyr RTOS environment. Haiwen addressed critical retention issues by relocating B92 driver code to RAM and updated RF power management configurations. His work demonstrated depth in driver development, hardware abstraction, and power management, resulting in improved device reliability, maintainability, and reduced field support requirements for production deployments.

May 1, 2025May 2025: Focused on stability and reliability for the B92 chip in telink-semi/hal_telink. Implemented a critical retention issue fix by relocating the B92 driver code to RAM, updated RAM execution attributes, and confined changes to tlsr9/drivers/B92/ in analog.c and clock.c. The work reduces retention faults in production and improves RAM utilization, delivering measurable business value through higher device reliability and lower field support needs.

Jan 1, 2025January 2025 monthly summary focusing on key accomplishments and business impact for telink-semi/hal_telink: Key features delivered: - BLE Low-Power and Exit Latency Optimization for B92 and TL721X: implemented exit latency mechanism to prevent disconnections, defined suspend and deep retention exit latencies, and configured during BLE controller initialization; updated Zephyr binary library references. For TL721X HAL, integrated power management (PM), PWM support, and updated BLE library to include PM; added exit latency optimization for low-power states. Major bugs fixed: - Resolved BLE disconnection risk in low-power modes by introducing structured exit latency handling and aligning PM transitions across the BLE stack and HAL. - Fixed timing and state-transition issues during wake/sleep cycles in the TL721X path through HAL PM integration and updated references. Overall impact and accomplishments: - Increased BLE connection reliability in low-power scenarios, reducing unexpected disconnects and improving user experience in battery-powered devices. - Improved power efficiency and predictability of wake/sleep cycles, contributing to longer battery life and more stable operation. - Streamlined maintenance with aligned PM implementation across HAL and BLE stack and updated dependencies (Zephyr binary references). - Clear traceability to commits enabling auditability and future enhancements. Technologies/skills demonstrated: - Embedded C / HAL, BLE stack integration, and low-power design - Power management integration (PM) and PWM usage - Zephyr RTOS environment and library management - Code maintenance, release readiness, and commit traceability
