The BlueNRG-1 single-core SoC, based on a 32MHz 32-bit ARM® Cortex®-M0, enables you to forge Bluetooth Smart applications with prolonged battery lifetime, minimizing overall cost and time-to-market. Its compliancy with the BLE specification and the embedded AES-128 and ECC-256 crypto engines enable top-notch security and privacy. The wide set of peripherals, easy code upgradability, the extended temperature range (up to 105 °C) and the premium +8 dBm output power represent a unique recipe for uncompromised performance. The innovative ultra-low-power design includes support for fast wake-up and sleep transitions and unrivalled sub-1μA standby current. The device comes with a brand new SDK and a sensorized development board for quick application prototyping. The BlueNRG-1 comes in both QFN-32 or WLCSP-34 packages.
The properties of the DECT protocol make it hard to intercept a frame, modify it and send it later again, as DECT frames are based on time-division multiplexing and need to be transmitted at a specific point in time.  Unfortunately very few DECT devices on the market implemented authentication and encryption procedures   - and even when encryption was used by the phone, it was possible to implement a man-in-the-middle attack impersonating a DECT base station and revert to unencrypted mode - which allows calls to be listened to, recorded, and re-routed to a different destination.
