  • Patent number: 10295990
    Abstract: A programmable power tool and method and systems of programming a power tool using wireless communication. An external device having a processor and a transceiver establishes a communication link with the power tool. The external device receives, with the transceiver, a first mode profile stored on the power tool. The first mode profile is defined by a profile type and a first value associated with a parameter for executing the profile type. The external device displays a control screen including the profile type and the parameter at the first value, and receives a user input. The external device generates, in response to the user input, a second mode profile by modifying the parameter to be at a second value. The external device transmits, with the transceiver, the second mode profile to the power tool.
