블루투스 로우 에너지 (BLE) Jobs

Project Description Bullet Points Project Overview: Develop an AI-driven management and reservation system for EV battery swapping stations. The system will enable users to monitor battery health (State of Charge/State of Health), locate available stations, and reserve battery slots in real-time. Core Functionality: User Interface: Create a dashboard/mobile app for users to track battery status, view station availability via GPS, and manage reservations. IoT & Hardware Integration: Interface microcontrollers (e.g., ESP32/Arduino/Raspberry Pi) with sensors (voltage, current, temperature) to transmit real-time data to a cloud server. AI/Predictive Analytics: Implement AI models to optimize charging strategies, predict battery health, and forecast station demand. Backend & Cloud:...

I have an existing Voice AI application built with LiveKit and Azure AI that is already fully functional. I'm looking for an experienced developer to make a few improvements before deployment. This is a small project that should take approximately 2–3 hours and needs to be completed within 24 hours. Tasks Reduce AI response latency to create a faster, more natural conversation. Rewrite the prompts so the assistant gives short, direct answers instead of long responses. Fix the call flow so the AI doesn't end outbound calls before the customer has clearly confirmed. Add proper call-ending logic for inbound calls when the conversation has naturally finished. Requirements Proven experience with the LiveKit Python SDK. Experience working with Azure OpenAI and Azure Speech Serv...

We are seeking experienced Hardware Development Engineers with a minimum of 5 years of experience to lead the end-to-end development of a consumer-grade embedded IoT system. This is a collaborative project requiring close coordination between hardware and firmware teams to deliver a production-ready industrial IoT device with advanced wireless capabilities and sensor integration. HARDWARE DEVELOPMENT ENGINEER Key Responsibilities: - System-level hardware architecture and design freeze - Component selection (MCU/SoC, power ICs, storage interfaces, wireless modules) - Schematic design and PCB layout (high-speed + mixed-signal, EMI-aware) - Power integrity, grounding, shielding, and DFM/DFA compliance - Prototype fabrication support and manufacturer Q&A - Hardware bring-up support and va...

We have an Android app (TC58) that prints ShipStation shipping labels (4x6 PDF) to a Zebra mobile printer over Bluetooth. We need a definitive fix for unreliable PDF Direct printing and a robust default path that works across power cycles and app sessions. Current setup Device: Zebra TC58 (Android handheld) Printer: Zebra mobile thermal printer (Link‑OS 6.x) over BLE Labels: ShipStation 4" x 6" PDFs (~63 KB) SDK: Zebra Link‑OS Android SDK (Bluetooth + FileUtil/sendFileContents) What we’ve tried and observed We toggle (PDF Direct) per print: set to pdf before print, none after. This is wrong per Zebra docs; only applies after a printer restart. After the first successful label, subsequent prints often fail silently (no label) or “corrupt” printer state ...
