Method of exchanging data packages between first and second portable communication devices
First Claim
1. A method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument, the method comprising:
- generating, by the first portable communication device, a first data package belonging to a first packet category comprising audio data or to a second packet category without audio data;
adding an acknowledgement indicator with a default setting to the first data package;
transmitting the first data package from the first portable communication device to the second portable communication device through the wireless communication channel;
if the first portable communication device receives a second data package, and if an acknowledgement indicator in the second data package is set;
generating, at the first portable communication device, a third data package comprising an acknowledgment indicator setting reflecting successful or failed receipt of the second data package; and
transmitting the third data package to the second portable communication device through the wireless communication channel; and
if the acknowledgement indicator in the second data package is unset, or if the first portable communication device fails to receive the second data package;
setting the acknowledgment indicator in the first data package to reflect failed receipt of the second data package; and
retransmitting the first data package from the first portable communication device to the second portable communication device, wherein the retransmission of the first data package is carried out for at the most N times if the first data package belongs to the first packet category, N being a positive integer between 1 and 4.

Abstract
The present disclosure relates to a method of exchanging data packages between first and second portable communication devices over a bi-directional wireless communication channel. The method includes generating, by the first portable communication device, a first data package belonging to a first packet category comprising audio data or to a second packet category without audio data and transmitting the first data package from the first portable communication device to the second portable communication device through the wireless communication channel. Where an acknowledgement indicator of the second data package is unset or the second data package is absent, the first portable communication device retransmits the first data package from the first to the second portable communication device for at the most N times if the first data package belongs to the first packet category; N being a positive integer between 1 and 4.

16. A wireless binaural hearing aid system configured to exchange data packages over a bi-directional wireless communication channel, the hearing aid system comprising:
-
a first hearing instrument comprising a first radio transceiver, and a first communication controller coupled to the first radio transceiver; and a second hearing instrument comprising a second radio transceiver, and a second communication controller coupled to the second radio transceiver; wherein the first communication controller is configured for; generating a first data package belonging to a first packet category comprising audio data or to a second packet category without audio data; adding an acknowledgement indicator with a default setting to the first data package; and transmitting the first data package to the second hearing instrument through the wireless communication channel; if the first portable communication device receives a second data package and if an acknowledgement indicator in the second data package is set; generating a third data package comprising an acknowledgment indicator setting reflecting successful or failed receipt of the second data package, and transmitting the third data package to the second hearing instrument through the wireless communication channel; and if the acknowledgement indicator in the second data package is unset, or if the first hearing instrument fails to receive the second data package; setting the acknowledgment indicator in the first data package to reflect failed receipt of the second data package; and retransmitting the first data package to the second hearing instrument, wherein the retransmission of the first data package is carried out for at most N times if the first data package belongs to the first packet category, N being a positive integer between 1 and 4.
