Bluetooth Jobs

I'm looking for an experienced PCB designer to review and fix a double-layer PCB for a consumer electronics bluetooth relay application. I currently have KiCad files along with a BOM and CPL files. I have been unsuccessful getting this all the way from design to production. I also want to retain copies of revised KiCad files along with BOM & CPL files. I would expect this should take someone under 10 hours, if you are looking for a simple easy and fast task. Key Requirements: - Design a double-layer PCB - Application: Consumer electronics (Bluetooth) - Assist with ordering process through Ideal Skills and Experience: - Proficiency in PCB design software - Experience with double-layer PCBs - Knowledge of communication modules and consumer electronics - Familiarity with JLCPCB...

I have an RFID reader that must talk directly to an Android device over Bluetooth, but the manufacturer never released an SDK. I need someone who can reverse-engineer or otherwise interpret the reader’s raw Bluetooth packets, pull out the numeric data stored on each tag, and feed that information into a brand-new Android app built specifically for this purpose. Here’s how I picture the workflow: • The app scans for and pairs with the reader via standard Bluetooth settings. • Once connected, it listens for the reader’s data stream, decodes each frame, and extracts only the numeric payload from every tag scan. • The app then displays the tag number on screen in real-time (simple list view is fine for now) and stores it locally for later export. I can p...

I want an ultra-low-power driver board that can run a small E-Ink panel completely untethered. The module must expose both WiFi and Bluetooth so it can receive data from a web API or a local mobile app and refresh the screen on demand. Power autonomy is critical: in addition to a rechargeable battery the board should accept a compact solar cell and scavenge ambient 2.4 GHz energy (WiFi harvesting) to keep the system alive for months without manual charging. Core expectations • Electronics: schematic, component selection and PCB layout optimized for sub-100 µA standby, including the WiFi/BLE SoC, power-path management, solar MPPT, RF-to-DC harvester and battery protection. • Firmware: ESP-IDF/Arduino or similar code that boots, joins WiFi or BLE, pulls a JSON payload, d...
