FMC234 Tracker Immobilizer Scenario

Can driver be identified when the tracker is in Deep Sleep, before turning on the ignition and waking up the tracker?

Example scenario:
Tracker is in Deep Sleep. Driver sits in the car and puts tag to 1-wire reader and only then puts the key into the car and turns on ignition. The tracker wakes up, will the Immobilizer scenario block the start of the car or the driver will be allowed to start the car?

Hi @useri

Good day. In the immobilizer scenario, the device should detect the ignition source first so that the tracker can activate its DOUT.

For more information please check the wiki pages below:

Immobilizer

Deep Sleep
FMC130 Sleep modes - Wiki Knowledge Base | Teltonika GPS

For your example, Theoretically, it will not work. The ignition should be started first so that the tracker wakes up from sleep mode. When the ignition is detected, it will activate its DOUT on that time the driver should tap the card to start the car.

Kindly make a test and try to start the vehicle very fast while the sleep mode is enabled if the car starts then disable the Deep sleep mode.

If you need additional assistance with the device configuration please contact your sales manager or create an HD ticket.

Thanks for the answer. Could you also answer these questions?

  1. What is the purpose of “The 1-wire enabled in DS and ODS”? Wouldn’t it would be used in my scenario (authorize the driver while in deep sleep)?
  2. There is an option “Bluetooth On While In Sleep”. If iBeacon comes and the tracker is in Deep Sleep, would it authorize the driver only after the tracker is waken up from the sleep (Deep Sleep in this case)? If, for example, iBeacon is transmitting every 10s, theoretically you couldn’t start the vehicle for up to 10s after turning on the ignition? Or it would authorize the driver even while in deep sleep?
  3. If DIN3 is selected as “Ignition Source”. I see few possible ways (just don’t know whether they would work):
    a. Momentary switch is connected to DIN3. After switch is pressed, ignition value quickly goes to 1 and back to 0 since it’s momentary switch. It would wake up the tracker, but still, DOUT for authorization would be inactive since ignition = 0? Or it would still have DOUT activated for some x time?
    b. Momentary switch is pressed and kept pressed (ignition = 1) while iButton is used to authenticate. After authentication, switch is released. “Ignition Off Timeout” in this case would allow the driver to start the car. Is this right?
  4. Magnetic iButton is used and left on the 1-wire reader. iButton is only removed when there is a need to “enable” the immobiliser scenario. Would the immobiliser be disabled if iButton is left on the reader, or there is some kind of limitation?
