Good day. Thank you for your question.
Kindly make changes to your Towing Detection settings in the Configurator (see attached - example) as this could be the reason why the event is triggered due to the movement or elevation detected by the device when the locks are taken off.
Also, you may disable the towing detection function either via Bluetooth, GPRS, or SMS command.
If you want to use SMS command, the structure is as follows:
With login and password : <login><space><password><space>setparam 11600:0
Without login and password : <space><space>setparam 11600:0
If you are sending via GPRS then you may skip the login, password, and <space>.
The parameter list can be found here - https://wiki.teltonika-gps.com/view/FMB920_Parameter_list#Towing_Detection
The SMS/GPRS command list can be found here - https://wiki.teltonika-gps.com/view/FMB_SMS/GPRS_Commands
If you would like to use the Bluetooth command then you may send the command via the serial Bluetooth terminal application that can be found in the play store - https://play.google.com/store/apps/details?id=de.kai_morich.serial_bluetooth_terminal&hl=en&gl=US
The command structure can be obtained from your Sales Manager. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to email@example.com
Thank you for your understanding.
