Power tool and method for wireless communication
First Claim
1. A power tool having multiple wireless communication states, the power tool comprising:
- a motor;
a battery pack interface that selectively receives a battery pack;
a backup power source;
a wireless communication controller coupled to the backup power source and the battery pack interface, the wireless communication controller including a wireless transceiver, a processor, and a unique tool identifier, the wireless communication controller configured to operate in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source, wherein, in the advertisement state, the wireless communication controller is configured to transmit an advertisement message including the unique tool identifier;
a switching network coupled between the motor and the battery pack interface;
an actuator;
a controller coupled to the actuator and the switching network, the controller configured to control the switching network to apply power from the battery pack to drive the motor based on actuator activation, wherein the controller is unpowered when the wireless communication controller is in the advertisement state and the battery pack is disconnected from the battery pack interface.

Abstract
A power tool having multiple wireless communication states and a method of wirelessly communicating by a power tool. The power tool includes a motor, a battery pack interface that selectively receives a battery pack, a backup power source, and a wireless communication controller coupled to the backup power source and the battery pack interface. The wireless communication controller operates in a connectable state when coupled to a battery pack and transmits tool operational data to the external device and receives tool configuration data from the external device. The wireless communication controller operates in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source. In the advertisement state, the wireless communication controller is configured to transmit the unique tool identifier. The external device may also display an indication of the communication state of the power tool.

17. A method of wirelessly communicating by a power tool, the method comprising:
-
detecting activation of an actuator; controlling, by a controller, a switching network of the power tool to apply power from a battery pack to drive a motor of the power tool based on the activation of the actuator; determining, by a wireless communication controller, that a battery pack interface is disconnected from the battery pack; entering, by the wireless communication controller, an advertisement state for wireless communication based on determining that the battery pack interface is disconnected from the battery pack; transmitting, by the wireless communication controller, an advertisement message including a unique tool identifier of the power tool when in the advertisement state; and maintaining the controller in an unpowered state when the wireless communication controller is in the advertisement state. - View Dependent Claims (18, 19, 20, 21)
