Hello,
I have another problem with the FMB920. I don't know if it's a bug or a feature, but for me it's a safety issue.
If i have my FMB920 connected to car battery, it wakes up from ultra deep sleep if the car is moving.
But if i disconnect the device from the car battery, it wont wake with accelerometer. No matter what i do, it stays in sleep mode until i reconnect it to car power system.
Is there anything i can do to make it work, so it wakes up and alarms me when someone disconnects it from the car battery?
