BLUETOOTH CONNECTION METHOD AND RELATED APPARATUS
A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.
Systems and methods for retransmission rate selection to support fast moving devices
The present disclosure is directed generally to systems and methods for dynamically selecting a retransmission rate for communication between two devices. The retransmission rate may be selected after a transmission has failed between the devices. In some embodiments, the retransmission rate may be selected based on relative velocity of the devices. In some embodiments, the retransmission rate may be selected based on transmission channel characteristics. The retransmission rate may be selected such that the retransmission will be less than an allowable transmission rate based on a distance between the two devices.
