I've just bought a Lekemi GPS tracker to protect my car. it works like this : if someone moves the car it sends to me an SMS message. And it sends to me another SMS if someone exceeds the speed threshold.
Now the problem: it does the same when it's me that uses the car. I would like to find a way to send two sms to the tracker a moment before I open the door of the car,so that it can turn off the alarms. And also I want to find a way to turn on the alarms when I go out of the car.
Inside the GPS tracker there is a SIM card with a mobile account. On my phone (Samsung Note 3) I've installed Android 8. So, I would like to find a way to have my Note 3 recognize the GPS signal of the tracker and send the SMS that I need. And it should also recognizes when the GPS signal is not present anymore.
Or do you have any other idea? The tracker does not produce a WI-FI signal. If it did it,I could have configured my phone to detect it from the right distance,for sending the sms....
