  • Establishing pairing between firearm accessories
    Patent number: 11997730
    Abstract: A method of pairing a device and a single one of two or more potential pairing devices includes first setting the device in a seek mode and scanning for the potential pairing devices. A list is stored in the device that includes any potential pairing devices discovered while in the seek mode. The list is stored in a sequential order based on a signal strength between the device and each of the discovered potential pairing devices. Then the device determines whether any of the potential pairing devices in the list are set in a predetermined mode, and pairs with the one of the potential pairing devices in the predetermined mode that has the highest signal strength.
