Abstract

Methods, systems, and devices are described for service discovery and connection establishment of a point-to-point (e.g., device-to-device) wireless communication. Wireless devices may initiate point-to-point communication utilizing ultrasonic signals. A user may initiate a scan for one device to detect, select, and establish a connection with another device, where the scan utilizes an ultrasonic signal. Once connected, the device may create a profile with one anther and/or wirelessly communicate with one another to, for example, exchange data.
