A first communication device (e.g., a radio) and a second communication device (e.g., an accessory) implement a wireless device pairing procedure to exchange numerical credentials so that the devices can subsequently form a link for communications using electromagnetic radio signals. The accessory transmits a beacon comprises a pairing request. Upon a user bringing the radio and accessory in close enough proximity, the radio receives the beacon using near-field apparatus included in the radio. In response to receiving the beacon, the radio initiates a pairing procedure, wherein the pairing procedure comprises a data exchange between the radio and accessory, and wherein the beacon and the data exchange comprise a non-propagating radio signal generated using the near-field apparatus. Upon completing the pairing procedure, the radio forms a link with the accessory to communicate using propagating electromagnetic radio signals.
