i would like to thank eve ryone who has helped towards the existence of this |
book without the work of many brilliant people contributing to the |
specifications there would be nothing to write about they are too numerous |
to list here but they are recorded in each of the bluetooth documents trying |
to develop standards of this complexity results in many days and evenings of |
wideranging discussions which have been both challenging and enjoyable it |
has been a pleasure to work with so many people of passion who are always |
ready to spend time explaining the intricacies of wireless audio and its |
application |
for taking the time to read through the drafts and coming back with detailed |
comments i would particularly like to thank richard einhorn kanji kerai |
ken kolderup mahendra tailor jonathan tanner and martin wool ley their |
input from a variety of differ ent reader angles has helped make this into a |
much better book than it would otherwise have been i must also thank the |
bluetooth sig for their help and support |

pivotal role in kickstarting the whole world of hearables many thanks to |
