Hello there,
Good day. Thank you for your question.
FMB003 does not have any inputs or outputs and there are no test points that can be used since it is connected directly to the OBDII port. As for the BT4.0 option, the base firmware does not have a feature for this so we can look into an additional development but there is some information needed for this.
Therefore, I would suggest that you reach out to us via VIP Helpdesk or contact your Sales Manager/Distributor that you made this purchase. 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 info@teltonika.lt
Thank you for your understanding.
Kind regards.
