Abstract
A method of performing a hail communication attempt includes checking capacitor voltage of a capacitor in a battery pack powering a hailing device to determine whether the capacitor voltage equals or exceeds a threshold voltage, and responsive to determining that the capacitor voltage equals or exceeds the threshold voltage, transmitting a hail (ping) message to a target device, determining whether the hailing device has received a responsive pong message from the target device, and responsive to determining that the hailing device has received a responsive pong message, terminating the hail communication attempt in preparation for sending data to the target device. Hail communication attempts are limited according to a predetermined number of consecutive groups of consecutive hail messages, with the capacitor voltage check occurring before the sending of each group. The method is compatible with target devices having different sniffing intervals, so long as those sniffing intervals have predefined relationships.
