/**
 * Ablauf des Verbindungsaufbau:/* ww  w . jav a 2  s  .co m*/
 * 1. Diese Klasse wird in einer externen Activity Instaziert (die externe Activity gibt einen callBackHandle mit)
 * 2. Die Methode connect() wird aufgerufen mit einer Bluetooth Device ID als Argument
 * 3. Connect() startet einen neuen Hintergrund Thread: ConnectThread damit das UI nicht einfriert beim verbinden
 * 4. Der ConnectThread ruft in seinem constructor schon die Android connect API funktion auf
 * 5. Die Funktion run vom ConnectThread baut dann einen Socket auf. Wenn das klappt wird ein weiterer neuer Thread vom Typ ConnectedThread gestartet connectThread ist damit zuende und luft aus
 * 7. Der ConnectedThread ffnet den Socket und luft auf ewig in einer Endlosschleife und wartet auf neue Daten
 * 
 * Ablauf des Empfangens:
 * 1. Der ConnectedThread liest Daten ein und schickt diese byte fr byte an process_incoming()
 * 2. wenn die checksumme stimmt und die daten vollstndig sind werden sie ber den handle zurck an die Activity geschickt
 * 
 * Ablauf des Sendens:
 * 1. send_save bekommt ein command, ein timeout und die anzahl an retries mit geliefert
 * 2. send_save ruft mit command und timeout send() auf
 * 2.1 send holt sich als erstes einen semaphore
 * 2.2 send_save muss warten weil es versucht sich den zweiten semaphore zu holen (es gibt nur einen und den hat send)
 * 3. send erstellt aus der payload ein packet und schreibt es auf den ConnectedThread, gleichzeitig wird ein timer gestartet
 * 4.1.1 wenn keine daten zurck kommen luft der timer ab und gibt einen semaphore frei (den send geholt hatte) dadurch wird send_save wieder aktiv
 * 4.1.2 send_save gibt den semaphore zurck und versucht den vorgang erneut (wenn die anzahl der retries es zulsst)
 * 4.2.1 wenn eine antwort kommt wird sie von process_incoming() empfangen und der semaphore wird zurck gegeben (den send geholt hatte)
