Abstract: An apparatus, a method and a computer program product is disclosed for a Bluetooth communication transceiver. The Bluetooth communication transceiver is configured as a Bluetooth low energy device performing timing measurements which are to be used for power saving. Based at least in part on the timing measurements, receive activation timings of the Bluetooth communication transceiver are adjusted. Further, a sleep clock of the apparatus may be used for calibration of the receive activation timings.

Abstract: The present system may enhance security in device having a wireless interface while it is operating in a mode that may make it more vulnerable to predatory attacks. More specifically, the advent of certain development or support operating modes supported by particular wireless communication mediums, such as debug modes that allow other wireless devices to monitor messages coming and going from a wireless device for diagnostic purposes, may leave devices overly accessible while operating in such a mode. As a result, additional security measures are required in order to determine if a vulnerable mode should be enabled on a device, and further, whether another device should be allowed to establish a communication to a device operating in this mode.
