Power tool communication system

A method of controlling a power tool, the method comprising:

• storing, with a first controller of an external device and in a first memory of the first controller, a mode of operation of the power tool, wherein the mode includes one or more power tool operational parameter values each corresponding to a power tool operational parameter, and wherein the first controller includes a first electronic processor;
• transmitting, via a first wireless communication circuit of the external device, first data corresponding to the mode to the power tool;
• transmitting, via the first wireless communication circuit, a firmware upgrade to the power tool;
• receiving, with a second controller of the power tool via a second wireless communication circuit of the power tool, the first data corresponding to the mode from the external device, the second controller including a second electronic processor and a second memory, the power tool including
• a housing having a device receiving portion configured to receive and couple to a power tool battery pack,
• a brushless direct current (DC) motor within the housing and having a rotor and a stator, and
• a trigger configured to be actuated to activate the brushless DC motor;
• determining, with the second controller, that the trigger has been actuated;
• controlling, with the second controller and in response to determining that the trigger has been actuated and while the trigger remains actuated, the brushless DC motor based on the one or more power tool operational parameter values of the mode included in the first data;
• receiving, with the second controller via the second wireless communication circuit, the firmware upgrade from the external device, and
• upgrading, with the second controller, firmware of the second controller based on the firmware upgrade received from the external device.

A power tool comprising:

• a housing having a device receiving portion configured to receive and couple to a power tool battery pack;
• a brushless direct current (DC) motor within the housing and having a rotor and a stator;
• a trigger configured to be actuated to activate the brushless DC motor;
• a wireless communication circuit configured to wirelessly communicate with an external device;
• and
• a controller including an electronic processor and a memory, the controller coupled to the wireless communication circuit and configured to:
• receive, via the wireless communication circuit and from the external device, first data corresponding to a mode of operation of the power tool, wherein the mode includes one or more power tool operational parameter values each corresponding to a power tool operational parameter,
• determine that the trigger has been actuated,
• control, in response to determining that the trigger has been actuated and while the trigger remains actuated, the brushless DC motor based on the one or more power tool operational parameter values of the mode included in the first data,
• receive, via the wireless communication circuit, a firmware upgrade from the external device, and
• upgrade firmware of the controller based on the firmware upgrade received from the external device.
