1. A method comprising:
- self-adaptation of a quality of non-audio data signal exchanged via an audio channel between a mobile terminal and an electronic payment accessory connected to said mobile terminal via an audio connector of said mobile terminal, wherein self-adaptation comprises;
sending over the audio channel, by one of said first mobile terminal or said electronic payment accessory, of a first reference signal to the other of said first mobile terminal or said electronic payment accessory, and at least one iteration of the following acts;
if, before the expiry of a predetermined duration and following the sending of the first reference signal, said mobile terminal or said electronic payment accessory receives a response over the audio channel coming from the other of said first mobile terminal or said electronic payment accessory;
modification, by said mobile terminal or said electronic payment accessory, of said first reference signal in taking account of at least one piece of quality information present in said response coming from the other of said first mobile terminal or said electronic payment accessory, delivering a first modified reference signal; and
sending over the audio channel, by said mobile terminal or said electronic payment accessory, said first modified reference signal to the other of said first mobile terminal or said electronic payment accessory;
when, following the sending of said first reference signal, there is no response over the audio channel coming from the other of said first mobile terminal or said electronic payment accessory at the expiry of the predetermined duration, sending over the audio channel by said mobile terminal or said electronic payment accessory of a second reference signal, distinct from the first reference signal, to the other of said first mobile terminal or said electronic payment accessory without sending again said first reference signal.

Abstract
A method self-adapts signal quality of non-audio data exchanged via an audio channel between a mobile terminal and a payment accessory. The method includes at least one iteration of the following acts: reception, by the mobile terminal, of a reference signal transmitted by the payment accessory; analysis, in the mobile terminal, of the received reference signal, the analysis delivering at least one item of information representative of the quality of the reference signal, referred to as quality information; transmission, by the mobile terminal to the payment accessory, of the quality information. In the above iteration, the roles of the mobile terminal and the payment accessory can be switched.
