Our Client is struggling to reduce active and sleep mode current consumption of their BLE Device. Tasks performed are - Debugging hardware to identify current thieves and provide a workaround - Debugging and optimization of Firmware to reduce current consumption. Developed multiple Low Power Peripheral drives to reduce current consumption Outcome - Reduce Active mode current with BLE connected from 200uA to 8uA. - Reduces Sleep mode current from 90uA to 1.5uA - Collectively these optimizations gave our client a battery life of 13 Years on Coin Cells

It was an amazing experience working with BIII TECH LLP. Goes above and beyond to get the project completed. Communication was concise and prompt, and there was a sense of accountability to help achieve the goals of the project. This was the first time working with BIII TECH LLP, and it won't be my last. Highly recommend!
