Logitech Details How Logi Bolt Differs From Standard BLE
The disclosure clarifies that Logi Bolt is not a new wireless standard but a Logitech-controlled BLE implementation that guarantees consistent security and performance.

Logitech shared with LTT Labs that Logi Bolt is based on Bluetooth Low Energy but uses proprietary optimizations. It enforces Security Mode 1 Level 4 for all connections, preventing fallback to weaker security. The MX Master 4 mouse uses the same Bolt protocol with improved antenna placement and doubled transmission power for better stability in crowded environments.
Logitech provided LTT Labs with a technical breakdown of Logi Bolt, the wireless protocol used in its mice and keyboards. According to the company, Logi Bolt is built on Bluetooth Low Energy but adds proprietary control over security, report rate, and RF behavior. The receiver enforces Security Mode 1, Level 4 for every connection, eliminating the fallback to weaker encryption that can occur with standard BLE. Logi Bolt also locks the report interval at 7.5 milliseconds, the fastest BLE allows, rather than letting the host vary it. The MX Master 4, released in October 2025, uses the same Bolt protocol as its predecessors but with a repositioned antenna and transmission power increased from +4 dBm to +8 dBm, which Logitech says improves stability in congested radio environments like offices.
