Power tool and method for wireless communication

A method of wirelessly communicating by a power tool, the method comprising:

• determining, by a wireless communication controller of the power tool, that a battery pack interface is connected to a battery pack;
• entering, by the wireless communication controller, a connectable state for wireless communication based on determining that the battery pack interface is connected to the battery pack;
• forming a wireless communication link with an external device in the connectable state;
• communicating, over the wireless communication link, to one or more of transmit tool operational data and receive tool configuration data from the external device;
• determining, by the 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;
• and
• transmitting, by the wireless communication controller, an advertisement message including a unique tool identifier of the power tool when in the advertisement state.

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 real-time clock coupled to the backup power source and configured to maintain a current time;
• 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 receive a lock out time;
• and
• a controller configured to receive the lock out time from the wireless communication controller and the current time, and further configured to lock the power tool upon determining that the current time exceeds the lock out time,
• wherein the wireless communication controller is further configured to:
• determine that a battery pack interface is disconnected from the battery pack;
• enter an advertisement state for wireless communication based on determining that the battery pack interface is disconnected from the battery pack;
• and
• transmit an advertisement message including a unique tool identifier of the power tool when in the advertisement state.
