Fast Bluetooth Human Interface

Descripción de la oferta
I need a working human-computer interface that can both pick up and broadcast data over Bluetooth at the highest speed the protocol allows. The data flowing through it will be full-rate cellular communications data rather than simple audio or text, so throughput and low latency are critical. On the input side the unit will read Qi energy and Acu-meridian energy via harness-style skin contacts. Those raw sensor signals have to be conditioned, digitised and pushed straight to a tablet over Bluetooth without noticeable lag. In the opposite direction the tablet will be able to transmit control or stimulation patterns back to the interface just as quickly. The job covers hardware design, embedded firmware and a basic demo app for a tablet or computer: • Hardware: schematic, PCB layout and component list for the sensor front-end and a Bluetooth 5.x radio able to sustain the required data rate. • Firmware: efficient, well-commented code that handles acquisition, buffering and bi-directional high-speed transfer. • Tablet demo: simple interface that shows live sensor streams and lets me send return signals for testing. I’ll consider the project complete when the prototype reliably moves continuous cellular-grade data between the skin-mounted harness and the tablet with no dropped packets during a five-minute stress test, and all design files are handed over in editable form.
