1. A method for using a short-range wireless communication link, the method comprising:
transmitting, by a source wireless communication device, data using and asynchronous connection-oriented logical transport (ACL) link of the short-range wireless communication link;
determining an amount of time that has elapsed since a high throughput event on the ACL of the short-range wireless communication link;
based on determining the amount of time, decreasing a first physical layer (PHY) symbol rate of the ACL to a second PHY symbol rate, wherein a link margin between the source wireless communication device and a second wireless communication device is increased based on altering the first PHY symbol rate of the ACL to the second PHY symbol rate; and
transmitting, by the source wireless communication device, data using the ACL and the second PHY symbol rate.
