Description

Peripheral device connection using local information Cross Reference to Related Applications This patent application claims the designation "PERIPHERAL CONNECTION USING LOCAL INFORMATION (peripheral device connection using local information)" filed on day 10/23 of 2023 and gives priority to U.S. patent application No. 18/492,684, assigned to the assignee of the present application. The disclosure of the prior application is considered to be part of the present patent application and is incorporated by reference into the present patent application. Technical Field Aspects of the present disclosure relate generally to wireless communications and techniques and apparatuses associated with peripheral device connections. Background A Wireless Personal Area Network (WPAN) is a short-range wireless network that is typically established by users to interconnect various personal devices, sensors, and/or appliances located within a certain distance or area of the user. For example, WPAN based communication protocols such as bluetooth ® (BT) protocol, bluetooth low energy protocol, or Zigbee ® protocol may provide wireless connectivity to peripheral devices that are within a specific distance (e.g., 5 meters, 10 meters, 20 meters, 100 meters) of each other. Bluetooth is a short range wireless communication protocol that supports WPAN between a central device (such as a host device or a source device) and at least one peripheral device (such as a client device or a receiving device). However, the power consumption associated with bluetooth communications operating on a Basic Rate (BR) and/or Enhanced Data Rate (EDR) physical layer may make WPAN communications impractical in certain applications. Accordingly, to address the power consumption challenges associated with bluetooth BR/EDR (sometimes referred to as bluetooth classical or bluetooth legacy protocol), bluetooth Low Energy (BLE) (also referred to herein as WPAN LE) has been developed and used in various applications where data transfer is relatively infrequent and/or to enable WPAN communications with low power consumption. For example, BLE utilizes infrequent data transfers by using low duty cycle operation and placing one or both of the central device and the peripheral device in sleep mode between data transmissions, thereby saving power. Example applications using BLE include battery-powered sensors and actuators in a variety of medical, industrial, consumer, and fitness applications. BLE may also be used to connect devices such as BLE-enabled smartphones, tablets, notebooks, earbud headphones, and the like. While conventional bluetooth and BLE offer certain advantages, there is a need for further improvements in bluetooth and BLE technology. For example, traditional bluetooth and BLE have a limited range, have limited data capacity throughput, and are susceptible to interference from other devices communicating in the same frequency band, such as via Wireless Local Area Network (WLAN) communications.
