Bluetooth 6.1 enhances privacy with randomized RPA timing

The Bluetooth Special Interest Group (SIG) has announced Bluetooth Core Specification 6.1, bringing important improvements to the popular wireless communication protocol.
One new feature highlighted in the latest release is the increased device privacy via randomized Resolvable Private Addresses (RPA) updates.
"Randomizing the timing of address changes makes it much more difficult for third parties to track or correlate device activity over time," reads SIG's announcement.
A Resolvable Private Address (RPA) is a Bluetooth address created to look random and is used in place of a device's fixed MAC address to protect user privacy. It allows trusted devices to securely reconnect without revealing their true identity.
Currently, RPAs are updated at fixed intervals, usually every 15 minutes, which introduces a level of predictability. This predictability can be exploited in correlation attacks, making long-term tracking possible.
