Generating a frequency hopping arrangement for a communication session involving a group of devices
Methods, apparatus, and processor-readable storage media for generating a frequency hopping arrangement are provided herein. An example computer-implemented method includes calculating a number of useable frequency channels between a starting frequency channel and a stopping frequency channel for a frequency hopping arrangement for a communication session; calculating a frequency channel step value based at least in part on a predetermined required minimum number of frequency channels for the frequency hopping arrangement; selecting frequency channel values to be used in the communication session by iterating through frequency channel values for the useable frequency channels between the starting frequency channel and the stopping frequency channel at intervals of a random frequency channel selection offset value; and establishing the frequency hopping arrangement based at least in part on the selected frequency channel values.

Wireless network with channel hopping
A wireless network with network-level channel hopping. A wireless network includes a wireless device. The wireless device includes a receiver, a data channel selector, and a transmitter. The receiver is configured to receive a beacon signal comprising a beacon sequence value. The data channel selector is configured to select, as a pseudorandom function of the beacon sequence value, a data channel on which to transmit in an interval following reception of the beacon signal. The transmitter is configured to transmit on the data channel selected by the channel selector.

Efficient rendezvous for distributed messages in frequency-hopping communication networks
In one embodiment, a rendezvous request message is generated (e.g., by a sender) that specifies a channel C and a rendezvous time T for which a distributed message is to be transmitted in a frequency-hopping computer network. The rendezvous request message is then transmitted on one or more channels used in the computer network based on reaching a plurality of intended recipients of the distributed message with the rendezvous request message prior to rendezvous time T. Accordingly, the distributed message is then transmitted on channel C at rendezvous time T. In another embodiment, a device receives a rendezvous request message, and in response to determining to honor the rendezvous request message, listens for the distributed message on channel C at rendezvous time T.

Bluetooth reconnection method and related apparatus
A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.
