Systems and methods that may be implemented to configure a single common radio frequency (RF) radio module with multiple link layers to allow the radio module to transmit different advertisement packets at the same time using different advertisement configuration parameters. A radio module may be simultaneously configured with the multiple link layers to allow the radio module to operate using unique different advertisement policies, and such that the radio module may selectively transmit…
Systems and methods that may be implemented to configure a single common radio frequency (RF) radio module with multiple link layers to allow the radio module to transmit different advertisement packets at the same time using different advertisement configuration parameters. A radio module may be simultaneously configured with the multiple link layers to allow the radio module to operate using unique different advertisement policies, and such that the radio module may selectively transmit advertisement packets in real time using any one of the different advertisement policies.

Systems and methods are provided that may be implemented to adaptively control advertising and/or scanning operations on multiple advertising channels in a wireless network environment. In one example, a wireless device may monitor for wireless activity from other protocols (e.g., such as Wi-Fi or Zigbee) on the frequency of one or more of the multiple advertising channels of a first wireless network protocol, such as a BLE wireless network protocol. The wireless device may respond in real time…

The invention relates to a method for a communication system comprising a first device and a second device. The method comprises transferring a packet from a first device to a second device, which packet comprises an authentication request having a challenge; encrypting the challenge from the authentication request by the second device; including the determined challenge as a challenge-response to a response packet by the second device; sending the response packet from the second device to the…

Systems and methods are provided that allow a BLE scanning device or other receiving device to use packet transmission timing parameter discovery to synchronize its listening times to the actual packet transmission times from a transmitting device such as a BLE advertising device. Once discovered, the packet transmission timing parameter/s may be used by the receiving device to calculate the same pseudorandom delay time component (such as BLE advDelay) that is being used by the transmitting…
Systems and methods are provided that allow a BLE scanning device or other receiving device to use packet transmission timing parameter discovery to synchronize its listening times to the actual packet transmission times from a transmitting device such as a BLE advertising device. Once discovered, the packet transmission timing parameter/s may be used by the receiving device to calculate the same pseudorandom delay time component (such as BLE advDelay) that is being used by the transmitting device to determine intervals between the transmitted packets. This allows the receiving device to calculate the exact time that the transmitting device is transmitting each packet, so that the receiving device may synchronize its listening times to coincide with the packet transmitting intervals used by the transmitting device.

Systems and methods are disclosed for listening window adjustments for power savings in BLE (Bluetooth low energy) communications. BLE devices determine time differences between assumed transmission times and actual receive times for packets transmitted by another BLE device. The BLE device then adjusts a listening window using the time differences, for example, to reduce the size of the listening window based upon the time differences. The adjusted listening window is then used by the BLE…
