Erkenntnisse
- Auf dem Tracker ist ein Kleber der sagt dass man das Gerät an die Stromversorgung anschliessen muss bevor man den USB Stecker einsteckt. Es geht nichts kaputt wenn man diesen Hinweis nicht beachtet, aber der Tracker startet im Firmware upload Modus.
- Der tracker emuliert drei serielle CDC Schnittstellen, leider funktionieren diese nur mit Windows, weil das Linux Modul die USB ID nicht kennt(?)
- Der erste serielle Port wird für debug informationen benutzt, am zweiten Port kann das Gerät programmiert werden. Der zweck des dritten Ports ist nicht bekannt.
- Der Tracker dürfte mit dem internen Akku zwischen 3h (GPS und GSM im dauerbetrieb) und 14h (GPS und GSM im standby) laufen.
