Abstract: A system for facilitating communications in a mesh network is provided. One or more devices of the mesh network may participate as routing nodes to provide range extension for any other devices in the mesh network that would otherwise be out of range from one another. In one or more implementations, Bluetooth Low Energy (BLE) may be used as the physical transport of the mesh network.

Abstract: A system and method using ANT and/or ANT+ protocols for one or more ANT and/or ANT+ applications. The system can include a Bluetooth interface and a Host Controller Interface (HCI) that are configured to process incoming and outgoing ANT and/or ANT+ messages from/to one or more ANT and/or ANT+ enabled devices. The ANT and/or ANT+ messages can be communicated to one or more ANT and/or ANT+ enabled devices utilizing a Bluetooth transceiver. The Bluetooth interface and the HCI can be configured to wrap one or more ANT and/or ANT+ messages with a header and/or to remove a header from one or more wrapped ANT and/or ANT+ messages. The header can be an HCI compatible header.

Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

Abstract: Systems and methods for implementing Bluetooth Low Energy (BLE) communications are provided. In some aspects, a method includes receiving, by a first BLE device, a first advertisement packet from a second BLE device. The first advertisement packet includes a payload encrypted based on a predetermined key. The method also includes decrypting the payload of the first advertisement packet using the predetermined key. The method also includes processing, by the first BLE device, the decrypted payload. At least one of the receiving, the decrypting, or the processing is performed without a BLE connection being established between the first BLE device and the second BLE device.

Abstract: A wireless device implementing secure connection establishment may include at least one processor circuit. The at least one processor circuit may be configured to receive an advertising packet from a device over a first channel and generate, in response to receiving the advertising packet, a connection request packet that comprises control information for establishing a connection with the device over a second channel. The at least one processor circuit may be further configured to encrypt and authenticate at least a portion of the connection request packet based at least in part on a connection entry key previously exchanged with the device and transmit the at least partially encrypted connection request packet over the first channel. The at least one processor circuit may be further configured to establish the connection with the device over the second channel based at least in part on the control information of the connection request packet.
