How Nordic’s nRF54L Series leverages 750-µs connection intervals to deliver up to 1.5-kHz update rates.
The Bluetooth Special Interest Group (SIG) recently introduced Bluetooth Shorter Connection Intervals (SCI) technology to reduce the minimum interval for Bluetooth LE connections to sub-millisecond levels. This enables the implementation of wireless applications with ultra-low latency, featuring connection intervals shorter than 7.5 ms.
Adding Bluetooth SCI involved various specification changes, including new control power-distribution units (PDUs) in the Link Layer, new host controller interface (HCI) commands and events, new feature exchange mechanisms, and other changes. However, it didn’t alter the radio, allowing it to run on the hardware found in existing Bluetooth devices.
In this video, Nordic Semiconductor's Joel Kauppo, Senior Product Marketing Engineer, demonstrates the company’s Bluetooth SCI technology and how it can lower latencies without compromising on performance.
