I want the CSR Harmony Bluetooth 5.0 driver since installing Windows 10 is proving difficult without it. CSR Harmony supports PC Bluetooth profiles as well as new Bluetooth low energy profiles for health and fitness devices, mice and keyboards and other PC accessories.ĬSR Harmony, which is built on CSR Synergy and BlueCore Host Stack, is an essential component of CSR’s Connectivity Platform for PCs (BCHS). CSR Harmony is a piece of networking tech that allows for a smooth wireless experience.
