No, wifi stomping occurs with both 2-wire and 3-wire. BT_PRIORITY just gives the MAC the ability to tell the difference between high priority TX and any bt activity requiring the air, so the MAC can then choose a weight based on differnet kinds of BT inputs. If all you have is two wire, then you don't get separate weight table entries for different kinds of BT transmissions. adrian On 9 April 2013 23:13, sandeep suresh <sandeep.suresh@xxxxxxxxxxx> wrote: > Hello Mr.Adrian, > Thanks for your response.
