Power tool and method for wireless communication
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.
