I have put my TAT240 in the I’m Alive status (242=1, period 3 hours) and in addition both On Move event record is Off and On Stop event record is Off. Now the tracker behaves how I want it, namely that it doesn’t send records. But it should, according to the documentation, periodically listen to GPRS commands. Now the question: Ho do I leave this sleep situation so that the device can react on the accelerometer and send GNSS messages? In the discussed situation it doesn’t reacts on anything.
