Methods and systems of exchanging data between an electronic device and an external accessory

A method (500) of exchanging data between an electronic device (105) and an external accessory (110). In one example, the method (500) includes receiving, at an interface of the electronic device (105), a connector (145) of the external accessory (110). The method (500) also includes transmitting, via a first pin of the interface, data between the external accessory (110) and the electronic device (105), and interrupting, with an electronic processor (220) of the electronic device (105), data transmission between the external accessory (110) and the electronic device (105) via the first pin of the interface. The method (500) further includes while data transmission is interrupted, detecting, via the first pin of the interface, an activation of a talk actuator (130), and activating, via the electronic processor (220), a transmitter (250) in response to detecting the activation of the talk actuator (130).
