Abstract
A communication system may include a first radio frequency (RF) device configured to generate a Bluetooth Low Energy (BLE) advertisement responsive to an input event, transmit the BLE advertisement in a BLE advertisement burst comprising a number of transmissions in at least one BLE advertising channel, and discontinue transmission of the BLE advertisement after transmission of the BLE advertisement burst. The system may further include a second RF device configured to scan for the BLE advertisement in the at least one BLE advertising channel, and communicate with the first RF device over a BLE data channel responsive to receiving the BLE advertisement.
