transmitting, with the electronic processor and over the second communication link, a command to the power tool device to control an operation of the power tool device;
receiving, with the electronic processor and over the first communication link, a command parameter from the external device, wherein the command parameter indicates whether (i) the command is transmitted by the wireless fob automatically in response to identifying the power tool device or (ii) the command is transmitted by the wireless fob only in response to the wireless fob receiving a user input;
receiving, over the first communication link and from the external device, a credential expiration period that indicates a first amount of time, after receiving the credential information, during which the wireless fob has permission to use the credential information to establish the second communication link;
ceasing, with the electronic processor, use of the credential information upon expiration of the first amount of time; and
receiving, over the first communication link and from the external device, an unlock duration time that indicates a second amount of time during which the power tool device is configured to be enabled after receiving the command from the wireless fob, wherein the command includes an enable command that allows operation of a motor of the power tool device in response to a trigger of the power tool device being actuated.
