Toestellen op Android 12 kunnen momenteel niet verbinden met onze app. Wij lossen dit z.s.m. op. Excuses voor het ongemak. 


Cannot connect

Please check the following:


Check that the E-Connect receives power. The minimum voltage for the E-Connect to turn on is 10.8V. If the battery has a reduced voltage, the E-Connect will not switch on. Even if the battery voltage drops below this level during your holiday, the E-Connect will switch itself off. As soon as the battery is charged or full again, the E-Connect will also switch on automatically.

Other things that can be checked:

  • Is the plug correctly inserted in the E-Connect and is the nut tightened?
  • Is the cable intact and are the + and – wires mounted correctly?
  • Does the battery generate at least 10.8V?
  • Have you fitted a switch and is it turned on?
  • Have you installed a fuse and is it still intact?
  • Check the status LED

Restart E-Connect

If the E-Connect does not respond properly or does not want to connect, it must be restarted.

  1. Disconnect the E-Connect from the power source by disconnecting it or turning the switch off
  2. Log out of the app and shut it down completely (also in the background)
  3. Turn off Bluetooth on your phone
  4. Reconnect the E-Connect, or turn the switch on again
  5. Turn Bluetooth on again on your phone
  6. Start the app and log in again

If you still cannot connect, check the LED light.

Testing power cable

If you have a voltmeter, you can check whether the cable is properly connected:

Check Bluetooth connection

Are Bluetooth and GPS enabled on the phone?

  • When the Bluetooth icon in our app is lit, you are connected
  • If the Bluetooth icon in our app is flashing, then a connection is being attempted.
  • On the E-Connect:
    • green LED: someone is already connected to the E-Connect
    • blue flashing LED: ready for connection
  • Restart the phone. This resets the Bluetooth chip on the phone, among other things.

On Android devices, a pairing request must usually be accepted before a Bluetooth device becomes visible. Usually a pop-up appears when Bluetooth is turned on in the phone. If this is not the case, please follow the next steps:

  1. In the phone, go to settings
  2. Under Connections, click Bluetooth Connections
  3. Click on SMART-Trailer to link under available connections

On iPhone, the connection is generally automatic. If this is not the case, follow these steps:

  1. Go to settings
  2. Select the E-Trailer app
  3. Turn on all permissions (location, Bluetooth, camera)
  4. Have you recently started using a new iPhone and installed your apps from a backup? This does not work well with our app. U dient de E-Trailer app te verwijderen en vanuit de App Store opnieuw te installeren.

Finally, it is not possible to be connected to the E-Connect with more than one device at the same time. Check that no other devices are connected to the E-Connect. If possible, turn off the Bluetooth on the other devices, or close the app.

Other check points

  • Ensure a maximum distance of 10 metres between the telephone and E-Connect and between E-Connect and the sensors.
  • Is there a connection to the Internet (via WiFi or your mobile network)?
  • If the software on the E-Connect has recently been updated, it may be that the E-Connect has to be restarted first.
  • If you install a new E-Connect, it may be that the old E-Connect is still linked to your account. Or if you have bought a second-hand E-Connect, the QR code may still be linked to the previous owner’s account. Read here what you can do in these cases.
  • Close the app completely (also in the background) and restart it.
  • Finally, switch off your phone and restart it.

If after all these checks the connection still fails, please send feedback to our Customer Support department via the app. We may be able to see in it exactly what is happening. We will then contact you to discuss and solve the problem.
