A METHOD OF EXCHANGING DATA PACKAGES OF DIFFERENT SIZES BETWEEN FIRST AND SECOND PORTABLE COMMUNICATION DEVICES

摘要

The present invention relates to 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 and a wireless binaural hearing aid system where at least one of the first and second portable communication devices comprises a hearing instrument. The method comprises generating, by the first portable communication device, a first plurality of data packages wherein a first subset of the first plurality of data packages belongs to a first packet category comprising audio data and a second subset of the first plurality of data packages belongs to a second packet category without audio data. The method further comprises transmitting the first plurality of data packages from the first to the second portable communication device and receiving, at the first portable communication device, a second plurality of data packages belonging to the first or second packet category from the second portable communication device; wherein a size of data packages belonging to the second packet category is smaller than a size of data packages belonging to the first packet category.
