Abstract
A method including receiving and storing a first signal strength threshold associated with obtaining access to a first access control device; receiving a first RF advertisement from the first access control device; obtaining a first received signal strength indication (RSSI) for the received first RF advertisement; determining that the first RSSI is greater than or equal to the first signal strength threshold; and transmitting, in response to the determination that the first RSSI is equal to or greater than the first signal strength threshold, a first RF message to indicate that the transmitting device is proximate to the first access control device.
